Lactobacillus buchneri

Heterofermentative lactobacillus strain which produces both lactic and acetic acid as well as small amounts of CO2. A great choice for Gueuze, Lambics, and Berliner Weisse because it results in a more ‘aggressive’ sour compared to other lacto strains, but still adds a ton of fruity and tropical notes.
