I am going to add to this list over time and include the vegan-friendly wines that I come across, how much they cost and where to buy them from in the UK. The ultimate aim will be to save you the time and effort of having to trawl through all the individual websites.
Polgoon Vineyard – all the wines available from Polgoon are vegan-friendly which makes it super easy to select. They have still reds, rosés and white wines and sparkling red and white wines available too. Single bottles range from £14.95 to £29.95 and they have various offers on cases of different sizes and combinations. I visited this vineyard in August 2020, click here for my post about my vineyard tour.
Hattingley Valley Vineyard – at the time of writing (June 2021) all the wines on the Hattingley Valley website are vegan-friendly. They are not highlighting this fact at all but I did check the details of each wine available and they all said suitable for vegetarians and vegans. This includes the following sparkling wines: Team GB Limited Edition Classic Reserve NV, Classic Reserve NV, Rosé 2018, Blanc de Blancs 2014, Kings Cuveé 2014, British Airways Blanc de Noirs, The English Gent and The English Lady and in addition their still wines: Still White 2020, Entice Dessert Wine 2020 and their Still Rosé 2020. Single bottles range from £19 to £80 so quite a wide range of prices.
