A43 Loki

Loki is a traditional Norwegian strain that has an extremely wide fermentation temperature range. This strain has traditionally been used in farmhouse style beers however, due to its wide range it can be used in a variety of beers from pseudo lagers to Belgian inspired beers. On the cool end of the range Loki is super clean; producing little to no esters and phenols. As things start to warm up, it tends to produce a huge fruity ester profile.

B44 Whiteout

This is the strain for Belgian Wit style beers. Whiteout produces an excellent balance of spicy phenolic character and esters. Along with the necessary aromatics, this strain produces a significant amount of acidity which is perfect for wits and other light colored Belgian ales. Whiteout can be flocculent during fermentation, then become non-flocculent at the end. This may lead to slower than normal fermentation.

B45 Gnome

Gnome is the yeast for brewing Belgian inspired beers in a hurry. This strain is extremely flocculent and drops out of the beer quickly after fermentation. Gnome produces a nice phenolic character that goes well with hops, as well as with caramel and toffee flavors. Great for Belgian ales that need to be crystal clear without filtration.

B48 Triple Double

The perfect strain for your classic abbey ales. Triple Double produces moderate esters with low to no phenolic characteristics.

B63 Monastic

This strain is a beautiful yeast for fermenting abbey ales, especially quads; high alcohol and dark Belgian beers. Monastic will produce beers with a high level of phenolic character and esters. It can be slow to begin fermentation but will easily dry out high gravity worts. This strain is a low flocking strain, so expect it to stay suspended for a long time.

Imperial Yeast

B64 Napoleon

This yeast is an insane wort attenuator. Napoleon will destroy the sugars in your saison and farmhouse beers – even the ones in which most brewer’s strains have no interest. When all is said and done, Napoleon produces very dry, crisp beers with nice citrus aromas. Yeast settling times can be long, usually requiring filtration for bright beers.

G01 Stefon

This is the traditional German strain used to produce world class weizen beers where big banana aroma is required. Balanced with mild clove, depending on your wort profile, this strain will produce amazing beers. Stefon will create a slightly higher level of acidity to give your beer a very crisp finish. Slightly underpitching will help increase the banana character.

Characteristics of this strain make it a good choice for traditional Berliner weisse fermentations. Kaiser is a low flocking strain, so expect long clarification times, but very low diacetyl levels.

G03 Dieter

Dieter is a clean, crisp, traditional German Kölsch strain. A very low ester profile makes this strain perfect for Kölsch, Alt and other light colored delicate beers.
