The UK fermented foods market is transitioning from niche wellness to mainstream chilled grocery. While precise category splits are rarely published, industry estimates place total UK fermented food retail value at £45–£80m, driven primarily by kefir and kombucha, with fermented vegetables showing faster percentage growth off a smaller base. Sauerkraut sits at the intersection of gut-health credibility, culinary rediscovery, and the post-UPF consumer reset.
