Marina Russian Farmhouse
While not technically Kveik, this S. cerevisiae strain from deep in Chuvashia in Russia is quite unique, and we thought it was worth sharing in the Kveik Ring program.
Marina displays notes of white wine, baking spice, and light vanilla. It is closest in profile to Belgian ale strains and would be at home in Belgian styles or as the primary strain in a mixed culture ferment. Traditionally, it is used in a rye-heavy boiled-mash beer.
Attenuation: 75-85%
Temperature Range: 20-35ºC
7 Million cells / mL
Our standard supply rate per single pitch. If you prefer a different rate, we can work with you to determine the optimal amount of yeast for your target recipe.
Attenuation values are always dependent on the type of wort brewed and represent an average. Depending on the wort that is produced, the yeast attenuation values may fall outside this range.
Temperature range is a suggestion and not the rule. Some brewers like to ferment with Saison strains hotter than the suggested range and Lagers colder than the suggested range. Feel free to experiment!
Diastatic yeast strains contain the STA1 gene which lets them break down more carbohydrates than a typical yeast resulting in very dry beers (High). Some strains have a deletion in the gene promoter which weakens this effect (Medium).
Based on attenuation at 48 hours fermentation in a standard wort fermentation.
This doesn’t mean you can only use this yeast for these styles. Feel free to experiment!
Criteria are based on the ASBC flocculation method. Wort production criteria such as calcium ion concentration and pH can impact actual flocculation performance in fermentation.
Alcohol tolerance can depend on additional criteria like yeast health and nitrogen supply. Low: <8%, Medium: 8-10%, Medium-High: 10-14%, High: 14-16%+
Many beer yeasts have mutations in the genes PAD1 and FDC1 that eliminate phenolic aroma production. Most Belgian, Saison and Wild yeasts have this trait intact, lending a distinct spicy character to the beer.
Based on production of beta-citronellol from geraniol in a standard wort fermentation (terpene biotransformation). Note that the concept of biotransformation also includes other aroma active compounds such as thiols and esters.
Flavour descriptions are based on a combination of analytical data (GC-MS) and sensory experiences.
