Urkel Yeast from Imperial Yeast

Urkel (L28)

From: Imperial Yeast
Type: Yeast  •  Packet: Liquid

Excellent choice for your Czech lager fermentations. Urkel allows for a nice balance between hops and malt. This strain can be slightly sulphery during fermentation, but it cleans up during lagering. Fermentation at the higher end of the range will produce a beer with minimal sulfur and a light ester profile with that classic Czech edge you are looking for.

Attenuation
Attenuation refers to the percentage of sugars converted to alcohol and carbon dioxide, as measured by specific gravity.
71-75%
Flocculation

Medium
Optimal Temperature
The optimal temperature is the range in which the yeast performs best without putting off any off-flavors. Pitching the yeast into wort usually happens at the low end of the temperature range.
