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 millennials 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.

We taste-tested over 30 varieties of kombucha to bring you our top buys, from plain options to interesting flavours (ginger, pink grapefruit and more) and options that can even replace sparkling wines.

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.

Best kombucha to buy 2022

No. 1 Living Ginger kombucha

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.

Bottle of HOLOS kombucha

Best ethical kombucha

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.

Bottle of JARR kombucha

Best passion fruit kombucha

Equinox Pink Grapefruit & Guava kombucha

Best pink grapefruit kombucha

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.

Left Field Sencha Green kombucha

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.

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.

A bottle of L.A Brewery kombucha

Best rosé alternative

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.

You + I Kombucha Original

Best smooth kombucha

Brewed in Glasgow, You + I 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.

Available from:
You + I, (£35, 12 x 330ml)

L.A Brewery Sparkling English Rose kombucha

Bottle of L.A Brewery kombucha

Best champagne alternative

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

Ocado (£10, 750ml)

How we tested kombucha

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.
