WLP518 Opshaug Farmhouse Kviek Ale Yeast
WLP518 Opshaug was originally sourced for White Labs by world traveler and blogger Lars Marius Garshol, who has authored several books on farmhouse ales and historical brewing. 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.
