From England, this yeast can ferment up to 25% alcohol when used correctly. It produces ester characters that increase with increasing gravity. Malt character dominates at lower gravities. To achieve >25% ABV, sugar needs to be fed over the course of the fermentation.

This popular German strain is used in the production of traditional, authentic hefeweizen. It produces a high level of isoamyl acetate, giving the resulting beer notes of banana. With balanced phenol production, this strain produces notes of clove but remains banana forward. Low flocculation leaves the desired cloudy look, appropriate for the German wheat beer style. Pitching rate and temperature will dramatically affect the flavor and aroma of this strain. Traditional brewing techniques suggest underpitching to produce more classic characteristics of the style.

This strain ferments much cleaner than its hefeweizen strain counterparts. It produces very slight banana and clove notes and has low flocculation, leaving resulting beers with characteristic cloudiness.

This is former Yeast Lab W51, the description originally used by Yeast Lab still fits: “This strain produces a classic German-style wheat beer, with medium to high spicy phenolic overtones reminiscent of cloves.” Pitching rate and temperature will dramatically affect the flavor and aroma of this strain. Traditional brewing techniques suggest underpitching to produce more classic characteristics of the style.

This strain produces a balance of phenolics and esters. Nutmeg, clove, and spice are more dominant than the banana and bubble gum aroma. Pitching rate and temperature will dramatically affect the flavor and aroma of this strain. Traditional brewing techniques suggest underpitching to produce more classic characteristics of the style. This strain has low flocculation and minor sulfur production.

Sourced from a Belgian monastery, this strain is ideal for Belgian quads, tripels and dubbels due to its high alcohol tolerance. It produces characteristic notes of plum and cherry with a hint of bubble gum. Lower fermentation temperatures (65-67°F/18-19°C) result in less fruity and more earthy beers.

Sourced from our friend Lars Marius Garshol, this Kveik strain was isolated from a mixed culture which belonged to Harald Opshaug, a farmhouse brewer in Stranda, Norway. This strain was originally used in the 1990s to produce several kornøl-style beers. It is a clean fermenting yeast and has tolerated temperatures up to 95°F (35°C) while finishing fermentation within three to four days. The hop-forward, clean characteristics of this strain make it ideal for IPAs and pale ales.

Hornindal is a Kveik strain shared with the world by Terje Raftevold from Hornindal, Norway. It produces an intense tropical flavor and aroma with notes of fresh tangerine, mango, and pineapple, ideal to be used with fruit-forward hops.

This is a traditional Belgian abbey strain perfect for use in dubbels, tripels and Belgian strong ales. Produces cherry, plum and pear esters. Medium flocculation results in clear, drinkable beer.
