The Ultimate Guide to the Best Green Tea Brands

Best green tea brands - The ultimate guide

A while back, I published a guide on my blog explaining what to look for when buying green tea. It’s really important you choose only the best quality green tea to reap all the health benefits and to avoid harmful toxins that lower-quality green teas may contain.

When it comes to green tea brands, there are many options out there but not all of them are good. How do you know which brands are good and who to trust? Buying the best green tea is certainly not easy. For this reason, I decided to put together this post listing some of the best green tea brands you can find online. I’ve carried out extensive research on each of the brands mentioned here and have even contacted them personally to gather information about their green tea which I couldn’t find on their websites.

During my research, I’ve tried many of the brands mentioned. I also discovered some new brands which I decided to include here due to good online reviews and because they meet my strict criteria.

What makes a good green tea brand?

The best green tea brands pay a lot of attention to sourcing their raw materials and will not settle for low quality. They take into account various factors that may affect the quality of tea and follow strict guidelines and procedures to ensure the tea produced is of the highest quality.

To make sure the green tea you are considering buying is of good quality, the following points should be considered:

  • Pollution. Green tea should ideally be grown in unpolluted areas, away from motorways, factories and industrialised towns. That’s because pollution from these sources will contaminate green tea with lead. China is considered one of the most polluted countries in the world, so green tea from China is usually not the best, although there are areas which may be pollution-free. However, it’s very hard to know where Chinese green tea comes from (if it’s not stated on the packaging or a website) and for that reason, Japanese green tea is normally a better choice.
  • Form of green tea. The best quality green tea will be in loose-leaf form, not in the form of tea bags. This gives the green tea leaves room to fully expand and release all their flavours and beneficial compounds.
  • Pesticides. Healthier green tea contains no pesticides and it’s certified organic.
  • Harvesting. Loose leaf tea should ideally be hand-harvested since machine harvesting breaks or tears leaves. When leaves are broken, this affects the quality of tea. The antioxidant levels are affected as more surface area is exposed to light and air. This also affects the taste.
  • Type of green tea. There are several different types of green tea and they all have different flavours and properties. Out of the loose leaf green tea types, Sencha green tea has the most antioxidants but the taste is mildly grassy, which not everyone will love. Matcha powdered green tea is another variety, with a fresh, smooth finish. It contains even more antioxidants than Sencha green tea and has its own unique properties.
  • Tea bags. Although loose leaf tea is always better than tea bags, sometimes it’s more convenient for you to use tea bags (for example, when travelling). When this is your preferred option, make sure you choose biodegradable tea bags which contain no microplastics.
  • Tea freshness and storage. The longer you store green tea, the more it will lose beneficial nutrients. You need to make sure you buy your green tea in small quantities and use it quickly to prevent the loss of antioxidants. It’s also good to know how green tea was stored before you bought it. To retain its value, green tea should be stored in an airtight container in a cool, dark place. It should never be exposed to heat, moisture or strong odours.
  • Toxins testing. Another thing to consider is if a brand has tested their green teas for any contamination by harmful toxins, even radioactivity. Not all the brands will be honest about this aspect but it’s worth investigating to make sure you buy only the best.

Taking into account all the factors above, I’ve carried out comprehensive research and found some of the best green tea brands, not only in the UK but the rest of the world also. I got in touch with the brands directly to ask them all the relevant questions to see how well they fit with the above criteria.

Best green tea brands

Here are further details about some of the best green tea brands. All are well worth considering since they tick the right boxes:

English Tea Shop

English Tea Shop works only with the finest organic and Fairtrade tea farmers, blenders and producers. Most of their green tea is sourced from Sri Lanka and comes from the “James Valley Organic Tea Estate” located in Gampola, which is a semi-mountain area 800 meters above sea level. Their green Sencha is grown in Kawane, Japan, on the Toha Farm which is away from densely populated areas. All their teas are certified by The Soil Association and also carry the Fairtrade International seal.

Teas from English Tea Shop are 100% hand-plucked which reduces their carbon footprint and produces better quality tea. To further reduce their carbon footprint, they also hand-pack their tea.

When it comes to testing for environmental toxins, English Tea Shop follows a strict guideline prior to selecting sourcing partners which ensures the authenticity and quality of all incoming teas and ingredients. What’s more, they conduct frequent testing on microbiology/pesticides and heavy metal tests in their lab as well as third-party accredited labs.

English Tea Shop organic green tea

Their CSV team (Create Shared Value) frequently engages with farmers, by conducting knowledge sharing sessions on investment and sustainability. This is done to ensure that farmers have sustainable living conditions and treat the environment in a responsible and ethical manner. In time, this will result in improved biodiversity which will yield cleaner and higher quality raw materials that will go into making their green tea.

English Tea Shop offers a variety of green tea products and that includes loose leaf green tea in square metal tins as well as tea bags.

Their tea bags are biodegradable and the pyramid tea bags are recyclable.

The brand sources very fresh teas, produced within a few days. Packaging takes a couple of weeks to complete, depending on the type of product. It takes around 3 weeks to get the items to the UK via sea freight. Coming in small quantities, the produce carries all the goodness and freshness of the earth.

Taking everything into consideration, there is no doubt that English Tea Shop is one of the best green tea brands you can try. I’ve tried their plain green teas and they are certainly of good quality and have plenty of flavour. Try some of the following:

  • Japanese Green Sencha (Senchado) – certified organic Sencha green tea is processed via a distinctively unique Japanese method. It is relatively mellow and greener than any other green tea.
  • Traditional Green Tea (The Tea of Life) – this organic green tea is processed according to traditional Chinese methods so the taste is slightly stronger than that of Japanese green tea.
  • Green Tea Pomegranate – if you don’t like plain green tea, try this blend containing antioxidant-rich super pomegranate and rose petals.

English Tea Shop green tea is available to buy from Amazon UK, Amazon US and eBay.

Hampstead Tea

Hampstead Tea is rated the No. 1 UK Ethical Tea Brand, focusing on strict principles of biodynamics to grow organic teas. This means they support natural processes of nature to grow tea holistically, paying attention to natural habitats surrounding the fields and working in harmony with the earth. This type of tea farming creates stronger crops and produces higher quality nutrient-rich plants that have greater vitality.

Hampstead's Tea Garden

Hampstead Tea leaves are hand-picked by skilled tea pickers and there is no plastic in their tea bags. Hampstead Tea was actually the first tea manufacturer to introduce staple and glue-free tea bags. Not only have they removed all plastics from their Loose Leaf Pouch and Tin range but what’s even more exciting is that they are the first tea manufacturer to introduce a non-GM plastic-free pyramid tea bag.

Apart from tea bags, Hampstead Tea also offer loose-leaf Darjeeling Green Tea, sourced from the Makaibari single estate in Darjeeling, India. This estate is one of the largest in Darjeeling and its tea plantations are grown in an unspoiled area on the slopes of the Himalayas and surrounded by primary rainforest. The tea plantations are surrounded by screens of giant bamboo which provide additional protection from air pollution. Hampstead Tea also source their green tea from the neighbouring estate of Makaibari (Longview) which is biodynamic.

Hampstead Organic Green Tea - loose leaf

All green tea from the Hampstead Tea brand is grown away from pollution and is naturally organic due to the biodynamic farming methods used to produce it.

Once harvested, green tea is immediately steamed, to lock in the freshness. It is packaged within hours of being picked and stored in lined Kraft bags which protect it from moisture and maintain its freshness. After harvesting, it is transported by sea so it takes at least 5 months before it goes on sale. Once it arrives in the UK, it’s stored in a dry warehouse, eventually being put into separate branded packaging.

Hampstead Tea products are constantly tested for pesticides and chemicals to ensure their purity and, according to the brand, none of their teas contains lead.

Here are the most popular green teas you can buy from the Hampstead Tea brand:

  • Organic Demeter and Fairtrade Clean Green Tea – Demeter is a biodynamic certification which is an international sign of quality and means that the product is organic, ethical, sustainable and made using environmentally friendly methods of production and processing.
  • Organic Demeter Green Tea Pouch – Loose leaf green tea that comes in a pouch made from Natureflex biodegradable material. Plastic-free packaging. A mouth-watering soft clean green flavour.

Hampstead Tea green tea is available to buy from eBay, Amazon UK and Amazon US.

The Tea Makers of London

The Tea Makers of London are loose leaf tea specialists who offer a wide range of the finest quality loose leaf teas, freshly sourced from some of the best tea estates in the world.

The Tea Makers of London Organic Dragon Well - cold

Not all of their green teas are certified organic but the ones that follow are:

  • Organic Dragon Well – often referred to as the national drink of China, Dragon Well green tea has a mellow and delicate flavour.
  • Organic Japanese Matcha – A great choice for anyone new to Matcha. Imparts a smooth, mellow flavour with hints of grassy sweetness.
  • Organic Ceremonial Grade Matcha – This ceremonial Matcha powder imparts a silky and rich texture with a wonderfully deep flavour. It’s the highest grade of matcha available.

Although not organic, I had to include here their popular Japanese Sencha Green Tea which comes from the Shizuoka’s popular tea growing region.

Their Organic Dragon Well is sourced from the Zhejiang province in China which is a coastal province with a landscape renowned for its scenic beauty.

The Tea Makers of London Organic Dragon Well - cold

Their Matcha teas are harvested and procured in Ise Bay, in the Mie Prefecture region in Japan. Farmers in this region have been producing high-quality green tea for over 800 years and they make use of ancient knowledge, as well as state-of-the-art technology, to create the most sublime green teas.

The Tea Makers of London Matcha green tea is hand-picked and so is their organic Dragon Well green tea.

Although The Tea Makers of London specialise in loose leaf tea they also offer green tea bags which are 100% biodegradable.

Their teas are tested at the source in accordance with EU regulations before being imported to the UK. The brand confirmed that there are no added chemicals, flavourings or any toxins such as lead in their teas.

Once harvested, the teas are vacuum packed which starves them of oxygen and prevents oxidisation. This ensures the tea leaves are as fresh when they arrive in the UK as they were when first picked from their source. Their exclusive seasonal teas are shipped straight after harvest.

The Tea Makers of London refresh their tea stock every six months and pack at their UK hub as soon as the shipments arrive. Their teas are stored at room temperature in their warehouse and their green tea has a shelf life of a minimum of 2 years.

Green teas from The Tea Makers of London are available to buy from Amazon UK and Amazon US. You can also buy them directly on their website.

Buddha Teas

Buddha Teas’ mission is to supply tea drinkers with the highest quality teas whilst at the same time, maintaining an affordable price point. They offer a wide range of teas which include green teas, premium blends and speciality teas. All their teas are organic and made from the freshest tea leaves. They offer loose leaf tea as well as tea bags which are bleach-free and plastic-free.

Buddha Teas are certified organic by the USDA (United States Department of Agriculture). This means that tea farmers follow strict rules to ensure the soil is only naturally enhanced and that no toxic synthetic substances have been used during tea production.

On their website, Buddha Teas make a bold promise: “Our promise is that you will never find better quality, reliability, or service than you will at Buddha Teas.” I don’t know whether this makes them the best tea seller but they are certainly one of the best tea brands, in my opinion.

Buddha’s green teas are sourced from China and Japan. Their Sencha (which is also the “green tea” they use in their blends) and Matcha come from the Kagoshima region, specifically from Chiran and Kirishima (the southernmost tip of Japan). They source tea from farms in both valleys and mountains which are far away from any pollution. Although the brand doesn’t test the teas for any contaminants themselves, the farms they work with do the testing and provide them with the test results.

To make the tea more affordable, Buddha’s teas are not hand-harvested, instead, they use several different machines to clean, trim, and harvest the tea leaves.

Harvest is done in April and once all processing is complete, the tea is shipped to a refrigerated warehouse in Los Angeles. As needed, they pull from that warehouse, and within a week they will have it packaged.

Buddha Teas have a good selection of different types of green tea and here are some of the most popular ones, plus those which caught my attention:

  • Organic Sencha Green Tea (tea bags) – the most popular variety of green tea in Japan, this tea has a smooth, mild flavour and is not bitter at all. Many loyal customers report this as being the best tasting Sencha tea they’ve tried.
  • Organic Acai Berry & Green Tea (tea bags) – this blend isn’t too green and isn’t too ‘berry’ flavoured. It has an uplifting taste with no bitterness.
  • Matcha Yuzu Ryokucha Loose Leaf – a special blend of classic green tea leaves, Matcha powder and Asian yuzu fruit which contains extra vitamins and nutrients. Citrusy and refreshing.

If you are based in other countries other than the US or UK, the good news is that Buddha Teas ship internationally although for some countries shipping may be a little bit expensive. There is free shipping on all orders over $50 within the United States.

Assamica Agro

Assamica Agro produces a variety of loose organic green tea blends but also a pure green tea called Assam Green Adventure. This is a savoury sweet organic green tea from Assam with a unique character and an autumnal feeling.

Organic Green Tea Assam Green Adventure

Assam Green Adventure is USDA certified organic green tea sourced from small scale tea growers from upper Assam, India (Prithvi Group of Small Growers, Dibrugarh). It’s hand-picked and processed using the green tea method of steaming the fresh leaves to better seal their properties. This variety of green tea is known to be one of the most delicious and smooth green teas available in India. It has a fresh, vibrant, and grassy flavour and can be re-steeped 3-4 times.

When you buy from Assamica Agro you are guaranteed freshness. You can also rest assured that Assamica Agro green teas are 100% chemical and pesticide-free since they are tested by the Tocklai Tea Research Centre for any impurities.

If you want the best green tea from India, this is it. Assamica Agro’s small growers from Assam have acquired the essential skills necessary to make one of the finest green teas in the world using their limited resources.

When you buy green tea online directly from the Assamica Agro store, you will get the freshest green tea from the field since it does not have to follow the traditional route of tea distribution, taking several months to reach your home.

The brand offers worldwide delivery and free shipping when you spend $50+. Check out their Indian website here and get 10% off with a discount code BEHEALTHYNOW10.  Or, go to the Assamica Agro international store here (if you are in the US, UK, Europe, Canada and Australia).


In general, Japanese green teas are healthier as they contain fewer contaminants. However, Teavivre deserves to be mentioned as one of the best Chinese green tea brands. When I discovered them during my research, I was impressed.

When you go to one of the pages of their website to learn more about each of Teavivre’s green teas, all the information is there. You can see exactly where the tea has been grown and there is even a map which shows you exactly where this is. All organic teas are certified organic by USDA and they also carry an EU organic certification.

Qiandao Lake Organic Tea Garden
“Qiandao Lake Organic Tea Garden is located in Chun’an County, Hangzhou City, Zhejiang Province,China. Nourished and influenced by the water of Qiandao Lake, the tea plants here are grown in a pure natural and pollution-free environment, which also gives the tea itself a natural sweet aftertaste. It is one of the source tea gardens of Teavivre’s”

The brand was established in 2011 and throughout the years they have explored the best tea regions, farms and producers. They only wanted to bring the finest teas to their customers, and they did. It’s no surprise that the brand has won several awards, for example, the Gold Medal in Global Tea Championship Competition in 2018 and the Great Taste Award in the UK in 2017.

On each of the website product pages, you will see exactly how the tea was grown when it was harvested and its shelf life. The taste and aroma are described in detail and you can learn more about each of the teas by reading customer reviews.

organic Longjing 2019 - TeaVivre

Teavivre offers a wide selection of the best Chinese green teas. Here are my top picks:

Teavivre offers worldwide delivery and free shipping for orders above $30. You can also buy their teas from Amazon US.

TeaVivre Authentic Chinese Teas


Clearspring sells a variety of green tea types, from Sencha green tea to Matcha green tea. Their teas are sourced from Kyoto in Japan and they are all certified organic by The Soil Association. Apart from loose leaf tea, they also offer green tea bags and Matcha powdered green tea.

Their green tea comes from Kyoto, famous for its numerous gardens and Buddhist temples. The green tea produced for Clearspring is grown on the outskirts of town, in an unpolluted area where lush, green hills abound.

To preserve the unique properties of the green tea and its nutritional benefits, the leaves are immediately steamed after picking. This process is sometimes referred to as the Sencha process and takes place within 24 hours of harvesting. This hinders the enzyme activity which is responsible for oxidation and helps to retain the bright emerald green leaf colour of the tea.

Their organic Sencha green tea has won a ‘Highly Commended’ award and has been ‘Commended By Consumers’ in the Organic Food Awards 2012. This no doubt accounts for something and is a good reason why this brand should be high on your list.

Clearspring’s green tea is ethically sourced and they follow strict environmental standards to reduce their impact on the planet. They also ensure their products are safe by testing for radioactivity when they arrive in the EU.

Clearspring green tea is available to buy from Amazon UK, Amazon US and eBay.

Heath & Heather

Established in 1920, Heath & Heather consider themselves to be the number one herbal tea and infusion specialist. Their organic green tea bags come in different flavours such as coconut, lemongrass, jasmine and Manuka. I’ve tried some of their flavours and found the Manuka flavour very enjoyable. They offer a greater variety of green tea flavours than any other brand so they are a good option for those who don’t like plain green tea. I must admit, some of their flavours are quite unusual so they are great for those who like to be a little bit more adventurous with their tea.

Heath & Heather source their organic green tea leaves from across China and South India and all the farms they work with are fully certified by the Soil Association. This means that they have to follow strict guidelines to achieve this status. This includes adhering to specific processing methods, correct storage, protecting the natural environment and packaging legislation. Their green tea is also certified by the USDA.

Heath & Heather teabags are made from soft woods, hard woods and long fibre (manila hemp). Their teabags are simply folded and sewn with string so they do not contain polypropylene (plastic), which is required for more traditional ‘heat sealing’ processes employed by many other tea companies.

From their selection of green teas, these are well worth a mention:

  • Imperial Matcha Green Tea – this tea is a blend of organic Matcha 3%, organic Chinese Sencha and organic South Indian green tea. Customers love it as it’s not bitter and has excellent taste. It’s refreshing and energising.
  • Organic Pure Green Tea – this tea has been carefully selected by expert blenders and you know it’s a winner since customers are continually happy with its flavour. The taste is subtle and light and not too strong.

Heath & Heather green teas are available to buy from Holland & Barrett, Amazon UK, Amazon US and eBay.

Best green tea bag brands

Although loose leaf tea is always better than tea bags, sometimes it’s easier to use tea bags, for example when you are travelling. Here are some of the best green tea bags that you can buy:

  • Hamstead Tea – their biodynamic and organic green tea is as pure as it could be and their tea bags are plastic-free and contain no glue.
  • Dragonfly Tea – their Pure Green Mountain Organic Green Tea (Formally called Emerald Mountain) comes from the lush green mountains of Southern China and it’s grown at high altitudes away from pollution. The tea bags are folded and stitched – they contain no plastic and are staple free. Different flavours are available.
  • Yogi Tea – If you like flavoured green tea, Yogi tea is a brand worth considering. Their green tea is grown in the hills away from any cities in China, mostly in the Zhejiang region. The green tea bags are biodegradable and plastic-free. Every batch of green tea is analysed for pesticides before being sold. It takes at least 4 months after the tea has been harvested before it goes on sale.
  • Pukka – certified organic, ethically sourced, fairtrade and plastic-free bags. Whole tea leaves are chopped just before packing tea into tea bags to preserve more flavour and the flavour is lighter because green tea leaves are flash dried. What I really like about Pukka’s teas is that they clearly state on their website where their teas come from. Their Supreme Matcha Green, for example, contains Chinese sencha green tea which is sourced from Da Zhang mountain, away from the biggest cities and the worst pollution. This tea also contains Oothu green tea which comes from the mountain range in India called the Western Ghats.
  • Clipper – Clipper green tea is a blend of green teas from different countries (mostly China I think) but at least it’s certified organic by The Soil Association. The teabags are plastic-free, biodegradable and non-bleached. The tea is also certified Fairtrade. Not the best quality green tea but it’s affordable.
  • Heath & Heather – they offer a wide range of flavoured green tea so if you don’t like plain green tea you will have plenty of choices.
