Vossa Nova™ is a Thiolized® version of Voss Kveik, known for reliable haze and tangy citrus notes. Our only kveik in the Thiolized series allows for a broad temperature range and control of the fermentation speed to your liking. Expect lower thiol intensity at hotter temps due to more vigorous blow off, along with no diacetyl production.

Thiolized® process
The Thiolized® process enhances a yeast’s ability to biotransform compounds found in malt and hops to unleash thiols — flavor- and aroma-active compounds reminiscent of grapefruit, passion fruit, and guava. Many brewers who include dry hopping in their processes are already familiar with the concept of biotransformation, or the development of new aromas and flavors due to yeast interacting with hop compounds.

What is DKO Technology?
DKO stands for Diacetyl Knock Out — a technology that knocks out diacetyl formation before it starts. Each strain utilizing DKO Technology expresses the ALDC enzyme, allowing you to streamline efficiency and quality without the diacetyl hang-up.
