BSY-A038 Bergen Bluestone Yeast is named after the region in Norway where Lars Marius Garshol isolated a number of traditional yeast strains.
BSY-A038 Bergen is traditionally used in the production of Norwegian Farmhouse Ale, this strain is a fast fermenter with good attenuation, a light earthy spiciness, marked tartness and unique ester profile of orange peel.
The BSY-A038 Bergen strain is prone to forming incredibly large flocs unlike any other yeast we’ve seen before, yet still remains highly attenuative.
BSY-A038 Bergen also exhibits the ability to ferment wort over a large temperature range, 21–37 ºC. At the cooler end of the range.
BSY-A038 Bergen is clean; producing little to no esters and phenols, but builds a huge fruit ester profile as the temperature increases.
