Kombucha – a lightly fizzy, fermented cold tea drink – has soared in popularity in recent years in the UK, with many more pre-bottled options recently popping up on the market.
The boom has likely been fuelled by several factors. Firstly, interest in fermented foods in general is on the increase, in part due to their gut-friendly credentials, and kombucha is no exception – it's said to have some interesting health benefits.
Secondly, with headlines focusing on the dangers of sugar-laden fizzy drinks, kombucha presents a lower-sugar, altogether more natural alternative.
Thirdly, recent reports have suggested that millenials in particular are turning away from alcoholic tipples and looking for low or no-alcohol options, with the result that more bars, pubs and restaurants than ever are now choosing to stock kombucha as part of their soft drink offering.
What is kombucha?
To make kombucha, firstly, the tea is brewed and sweetened with sugar to help feed the fermentation process. Next, a scoby is added (an acronym that stands for 'symbiotic culture of bacteria and yeast') along with some starter liquid.
A permeable lid is attached and the mixture left to ferment for several days – this is the primary fermentation. When the kombucha is bottled for its secondary fermentation, flavourings can be added, including fruit, herbs, spices or other ingredients such as coffee, coconut water or rose petals.
The end result? A live, fermented drink that is effervescent, slightly sour, and can be flavoured with a huge variety of ingredients. Just like wine or beer, every kombucha recipe is unique, with the flavour profile, appearance and level of fizz depending on which ingredients and methods have been used during the brewing and fermentation process.

Left Field Sencha Green kombucha, £2.50 for 330ml bottle
Left Field pride themselves on their unfiltered, raw kombucha, unadulterated with juices or flavourings, and it's easy to understand why – this green-tea-based brew is really something special. In the glass, it's pale, effervescent and almost champagne-like in appearance. The light aroma is delicate on the nose, with hints of apple and honey. To drink, it's clean and crisp with just the right amount of fizz. Full marks for this one and well worthy of a toast.
Real Kombucha Dry Dragon, £30 for pack of 12 bottles
Deliberately targeting the discerning drinker, Real Kombucha now find themselves on the drinks menus of some of the best bars and restaurants in the UK, including The Fat Duck, L'Enclume, The Hand and Flowers and Le Manoir. Their Dry Dragon kombucha is particularly delicious – delicate, bright and sparkling, with a dry finish. Walking the tightrope between acidity and sweetness with ease, it's a well-balanced flavour profile with lovely lemony notes. A great alternative to sparkling wine with a meal.
Blighty Booch Kombucha Organic Ginger, £38 for pack of 12 bottles
This North Wales-based brewery ferments premium quality organic whole leaf and bud tea from China in small batches to produce with a light and fruity beverage with a delicate effervescence. We love the ginger flavour especially, whose well balanced sweetness and warming, punchy flavour has earned it a coveted three stars from the Great Taste Awards.
JARR passion fruit kombucha, £2.65 for a 240ml bottle
This super-funky kombucha boasts a tangy passion fruit scent which balances well with the green and oolong blends of tea. We thought it was reminiscent of a fine scrumpy cider – great bubbles and ideal to refresh and revitalise you on a hot summer's day.
L.A Brewery tropical ginger kombucha, £30 for pack of 12 bottles
Get a taste of the tropics all year round with this wonderfully zingy tropical ginger kombucha from L.A brewery. Infused with an aromatic blend of ginger, hops and yuzu, their latest flavour creates a rich base balancing notes of tropical fruits and fresh citrus. Based in Suffolk, all of L.A brewery's drinks are inspired by founder Louise Avery's love of foraging and using local fruits, herbs and botanicals. Other flavours we love from this brand include their fresh lemongrass kombucha and the unusual combination of strawberry and black pepper which leaves a satisfying kick on the palate.
HOLOS Citra Hops kombucha, £29.99 for a pack of 12 bottles
West Sussex-based HOLOS makes fantastic-tasting kombucha while doing good – in partnership with two UK charities, it employs survivors of slavery, providing training and job opportunities. We enjoyed all its flavours but found the zesty, tropical notes of the Citra Hops blend particularly bright and refreshing. A worthy recipient of three stars from the Great Taste Awards, this kombucha is an excellent substitute for beer and has a satisfyingly crisp, dry finish. HOLOS is available for purchase in M&S stores nationwide.
J’aime Original kombucha, £29.98 for a pack of 12 cans
J'aime Drinks offers a sophisticated formulation which will especially appeal to those seeking a drier kombucha. Formed from a unique blend of four green and white teas, this well-balanced sparkling drink delivers delicate floral notes of jasmine alongside brighter citrus. Brewed in small batches, the end product contains zero sugar or additives, resulting in a refreshing, dry finish with a gentle effervescence. We also loved the stylish, tactile cans that the kombucha comes in, accentuating the wellness ethos of the J'aime brand.
L.A Brewery Sparkling English Blush, £10 for a 750ml bottle
A fragrant kombucha inspired by summer Rosé wines, L.A Brewery's latest flavour balances floral hops with tangy rhubarb, elderflower and seasonal fruits such as strawberry and peach. Initially dry on the palate, this refreshing kombucha releases layers of soft fruitiness, ending with a touch of acidity from the rhubarb. Ideal for sipping on lazy summer afternoons or cracking open for a special occasion.
Clever Kombucha Original, £35 for pack of 12 bottles
Brewed in Glasgow, Clever Kombucha is currently available in four flavours – but the original was our pick of the bunch, brewed with Assam tea in oak barrels. In the glass, it's a bright, golden colour, with a very unusual scent reminiscent of demerara sugar. Fine, delicate bubbles give a gentle burst in each sip, and stay stuck to the glass as it's swirled – if it were a wine, you'd say it 'has legs'. On the palate, it's oaky and full-bodied, with an almost alcoholic kick that makes you think of dark rum. There's very little acidic aftertaste, so if you prefer your kombucha with less 'tang', this might be a winner for you.
Equinox Pink Grapefruit & Guava kombucha, £36 for pack of 20 cans
Bold, bright and confident, this Equinox kombucha is one for fans of strong, citrussy flavours. Brilliant pink in colour, it packs a really punchy grapefruit scent. On tasting, an enjoyable sharp and sour tang awaits beneath the fruity top notes. Vividly tropical and truly moreish.
Genie Crisp Citrus kombucha, £25 for pack of 12 bottles
Don't let the intense orange colour fool you – this Genie kombucha has a refreshing, sophisticated flavour profile. The fruit flavour packs a real punch but, thankfully, lacks the synthetic aftertaste of some flavoured kombuchas. It has a vibrant aroma with hints of lemon, orange peel, and grapefruit, along with an inviting sweetness. The taste is complex – not too sweet but well-balanced with a zesty tang and a lime kick. It has a pleasantly dry finish and a subtle fizz. Crisp, lively and alert.
L.A Brewery Sparkling English Rose kombucha, £10 for a 750ml bottle
If you are celebrating a special occasion, this champagne-inspired kombucha makes the perfect swap for a fine bottle of bubbly. Tangy assam and white monkey green tea provide a delicate base for floral infusions of organic white rose petals and wild elderflower. We enjoyed the gentle effervescence of this drink along with the fine balance of fresh citrus flavours and wildflowers on the nose, culminating in a crisp, dry finish
Real Kombucha Royal Flush, £30 for pack of 12 bottles
This variety is brewed using first flush Darjeeling, which is hand-picked early in the spring for a delicate flavour – and it really shines in this kombucha. Pale yellow and lightly sparkling, it has a soft, peachy scent with a tangy undertone. It's more sour than some – but not in a bad way – with a crisp, dry finish that's altogether extremely enjoyable.
No. 1 Living Ginger kombucha, £1.75 for 275ml bottle
You get a real stem ginger aroma with a heady base of turmeric on opening this kombucha. It has a great balance of flavours – a subtle sweetness, a tang of acidity and a gentle heat from the ginger with a peppery finish. Pale yellow and translucent, its robust fizz really adds to the warming effect with each sip. A flavour-packed treat.
How we tested kombuchas
As kombucha is a live product that continues to ferment once it's bottled, it's important to store it correctly to slow the fermentation process and to avoid changes in taste – so all the samples were chilled immediately on delivery.
On the testing day, all samples were served chilled and poured into wine glasses with nothing added – no ice, lemon or straws. Notes were taken on the packaging, appearance, smell, taste and fizz and a score given to each kombucha. We included 33 samples from a variety of price points and brands for this review.
