White Labs - WLP518 Opshaug Kveik Ale Yeast

WLP518 Opshaug Farmhouse: Sourced from 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 kornol-style beers. It`s a clean fermenting yeast and has tolerated temps. up to 91F (33C) while finishing fermentation within three to four days. The hop-forward, clean characteristics of this strain makes it ideal for IPAs and Pale Ales.

Attenuation: 70 - 80

Flocculation: Med - High

Alcohol Tolerance: Med - High (8-12%)

Optimum Fermentation Temps: 77 - 86F

Each vial of White Labs liquid yeast is designed to be used directly in 5 gallons hence the term `pitchable yeast.` Each vial is equivalent in cell count to a pint starter or 75-150 billion cells. One vial will usually start fermentation in 5 gallons in 5-15 hours at 70F. If a faster start is desired or if initial gravity is over 1.070 we recommend a 1-2 pint starter be made.
