We produce a range of handcrafted and small batch kombuchas and seasonal botanical drinks.

Kombucha is a low sugar, low-alcohol drink made by fermenting tea, akin in flavour to a light cider or perry. Old Tree Kombucha is known for its well-balanced full flavour, delicately floral with a tangy, appley sweetness and champagne-like character. Best enjoyed as a low alcohol option at social events, or as a digestive aid with a meal, it also makes an incredible cocktail mixer with both gin and rum.

We carefully source the ingredients in abundance and use traditional brewing techniques to create hedgerow wines, tasty cordials and potent drinking vinegars. 

Old Tree Drinking Vinegars are drinking vinegars made from seasonal botanicals, twice a year for Autumn/Winter and for Spring/Summer. We carefully combine up to 20 botanicals into these elixirs, perfect for mixing in cocktails, diluting with sparkling or hot water, or having neat as a morning digestive booster. 

Old Tree Cordials are a delight for the senses-- made to be diluted to taste, our cordials capture the unusual flavours of the Sussex landscape such as Mulled Kombucha Cordial in the Winter and our Spring/Summer offering Nettle & Rhubarb Cordial. 

Old Tree Elderflower Sparkling Wine is the perfect celebration drink, produced in time to usher in the British summer months. This extraordinary drink is made with hand picked wild elderflowers from the sunny Sussex countryside at the peak of flowering season to create a heady, aromatic sparkling wine. This medium-dry, floral wine is sunshine in a bottle, evoking the best of the early summer. Pairs perfectly with a local cheese board.

Carefully curated ingredients

At Old Tree Brewery, we use only the best, high-quality ingredients to make our botanical drinks. We purchase organic sencha green tea, organic, single-estate Assam black tea, and organic, biodiversity-enhancing carbon-neutral sugar. All the water we use in our brews is charcoal-filtered through an industrial-grade filter.

For ingredients we cannot source locally, we do the research to ensure we are purchasing ethically sourced ingredients from local suppliers like HISBE.

We often use Sussex foraged ingredients like Lavender and Rosehips to flavour our drinks, or source our ingredients from local suppliers, or our own Drink Forest Garden at Rock Farm.

How we make our drinks

We are still a very small scale brewery, so we use 2 fermenters to make our kombucha brews. We use small batch brewing methods and traditional fermentation techniques to create a delicious kombucha. After the kombucha is brewed, we flavour our drinks by using and making our own hydrosols. A hydrosol is a water solution made from plants containing a mix of botanical essential oils and flavour compounds. We use a handcrafted alembic copper still from Portugal to hydrodistill botanicals and fruit.
