Fermentis SafAle™ BW-20 yeast 11,5 g

Fermentis SafAle™ BW-20

Specialty yeast designed for the production of wheat beers, in typical Belgian style, with fruity flavors and specific phenolic character (clove and peppery notes). Its less phenolic nature produces an aromatic but milder base beer, allowing for the expression of added ingredients, such as coriander or citrus peel.

This strain doesn’t ferment all the maltotriose, giving extra mouthfeel to the beer.

BW-20 has a medium sedimentation: forms no clumps but a
powdery haze when resuspended in the beer.

What distinguishes German and Belgian wheat beers?

Both beer styles share the common characteristic of being brewed with wheat, a difference from the usual barley malt. However, they differ significantly beyond this shared trait.  German Weizen, or Weissen, are generally limited to only a few selected ingredients: malt, wheat, hops, yeast, and water. These beers typically contain 40% malted wheat, although this ratio can extend up to 70%.

German Weizens adhere to these standards, which exclude the addition of extra spices.

Belgian Witbier, in contrast, relies on a lower percentage (not exceeding 40%) of unmalted wheat. The uniqueness of Belgian Witbier comes from the use of added spices like coriander, lavender, or orange zest or peels. Coupled with a less phenolic yeast, the base beer tends to be milder, serving as a canvas for the infusion of additional ingredients.
