| Wit (OYL-030) || || 72-76 || Medium || 62-75 || Produces a complex flavor profile dominated by spicy phenolics with low to moderate ester production. It is a great strain choice when you want a delicate clove profile not to be overshadowed by esters. It will ferment fairly dry with a slightly tart finish that compliments the use of oats, malted and unmalted wheat. This strain is a true top cropping yeast requiring full fermenter headspace of 33%. Compares to WLP400 and WY3944 vs Omega Yeast Labs Exclusive. Commercial pitches only.

Voss Kveik is non-phenolic and produces a beer with moderate citrus notes. It would pair very well with citrusy and fruity hops. This strain is not fast at the low end of the range so don’t be afraid to pitch in the middle to upper part of the temperature range. '''Available to homebrewers'''. The Voss kveik was originally a blend of at least 3-4 strains, however only one strain was cultured by Omega <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1207326749295537/?comment_id=1207856785909200&reply_comment_id=1207859749242237&comment_tracking=%7B%22tn%22%3A%22R9%22%7D Conversation with Lance Shaner and Lars Marius Garshol on MTF. 01/04/2016.]</ref> See [[Kveik]] for more information.
