Our brewery is strongly dependent on Morpheus yeast, our house yeast strain, which enables us to brew sour and non-sour beers. In 2008, our yeast whisperer Marc picked a wild yeast culture in the French Auvergne and patiently selected, isolated and cultivated the now famous Morpheus yeast to the desired standard.
Morpheus is a mixed culture of 2 yeast strains (saccharomyces cerevisae) and lactobacillus. In our Traditional Ales range, the lactobacillus is deactivated.
Morpheus yeast gives our beers the recognisable Alvinne touch. According to yeast whisperer Marc, you need 3 ingredients to nurture your house yeast; discipline, passion and love. Every single day!
