Bluestone Liquid Yeast – Bergen 120 ml

Name after the region in Norway where Lars Marius Garshol isolated a number of traditional yeast strains. 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. This strain is prone to forming incredibly large flocs unlike any other yeast we’ve seen before, yet still remains highly attenuative. Bergen also exhibits the ability to ferment wort over a large temperature range, 21–37 ºC. At the cooler end of the range Bergen is clean; producing little to no esters and phenols. But builds a huge fruit ester profile as the temperature increases.

Similar to: WLP4045 or Sigmond Voss

These Bluestone yeast packs have about twice as much yeast as White Labs or Wyeast packs. Therefore just one pack of Bluestone is usually enough for a 23L batch – no need to pitch multiple packs or make a starter!

Why Bluestone Liquid Yeast:

  1. Pure Culture – Bluestone ensure a pure culture with liquid yeast due to their proprietary propagation technique. Dried yeast, however, invariably has some degree of contamination due to the very nature of the drying process. Therefore, it is not recommended to re-pitch dried yeast.
  2. Greater Flavour Profile Range – Liquid yeast offers a greater flavour profile range compared to traditional dried yeast. Liquid Yeast also produces lower fusel alcohols, lower levels of acetaldehyde (which produce the off flavours) and superior, enhanced Esters (which produce crisper, fruitier notes) compared to dry yeast. The science speaks for itself.
  3. Multiple Generations – Pitch & Re-Pitch – Make your hard-earned $$ go further. With good yeast management, liquid yeast can be re-pitched between 5-10 generations with no noticeable loss of flavour quality or yeast health.
