What does Diastatic yeast mean?
diastaticus is beer yeast that can break down longer-chained carbohydrates (dextrins and starches) that regular yeast can’t. It doesn’t actually consume them directly, but it secretes an enzyme (glucoamylase) that breaks down dextrins outside the cell into smaller sugars that the yeast can then metabolize.
What is yeast killer factor?
Killer Strains are strains of Saccharomyces cerevisiae that contain a killer factor (sometimes also called a “zymocin”), rendering them resistant to infection by other yeasts. This was first discovered by Makower and Bevan in 1963.
What is POF in beer?
Lager yeasts are characterized by their inability to decarboxylate ferulic acid present in wort, a phenotype also known as Pof- (phenolic off-flavor). However, all known S. eubayanus strains characterized so far produce clove-like aroma specific of 4-vinyl guaiacol, a decarboxylated form of ferulic acid.
Is Kveik a Diastaticus?
They are also non-diastaticus, meaning they do not produce glucoamylase to allow them to break down much longer chain starches and dextrins and seriously drying out the beer like a Brettanomyces yeast strain. They’re very typical and safe Sacc yeast strains to introduce into your brewery.
What is sta1 yeast?
STA-1 is a marker in yeast that indicates it has mutated or become a diastaticus variant of the normal Saccharomyces Cerevisiae. Once detected in a yeast strain, the strain is then properly identified as Saccharomyces cerevisiae variant Diastaticus.
What is saison yeast?
Saison yeast produces fruity esters reminiscent of lemon and orange citrus notes. They often produce a slightly peppery aroma also. Some of the modern ones tend to produce small amounts of isoamyl acetate, which is the banana/bubble-gum flavour found in wheat beers.
Are yeasts toxic?
At that time, it was shown that certain yeast strains secrete protein toxins that are lethal to sensitive strains. The toxin-secreting strains were designated ‘killer yeasts’, and the term ‘killer toxin’ was used to describe the secreted proteins.
How is kveik pronounced?
To put it simply, kveik (think “kuh-vike”, as a native speaker would pronounce it––not “kwike”) is a traditional Norwegian word for a type of ancient, domesticated yeast.
Is kveik yeast Diastatic?
All the known kveik strains can be dried, because this was the traditional way to preserve yeast in Norway. The kveiks are all non-phenolic, and non-diastatic, unlike the saison yeasts, which belong to the Beer 2 family.
What is Saccharomyces cerevisiae var Diastaticus?
Saccharomyces cerevisiae var. diastaticus is described as a super-attenuating yeast due to its ability to ferment residual carbohydrates in beer (dextrins and soluble starch), which are not normally metabolized by pure culture yeast strains.
What is Saison in English?
Noun. saison f (plural saisons) season (one of the four parts of the year in temperate regions: winter, spring, summer and autumn) season (a certain time of the year, when something in particular happens)
Will S-33 make a good New England style beer?
I have made an order for some grains, hops and yeast and I will be giving S-33 a go for a 4.5% ABV beer, with oats and some hops. Hopefully, it will yield an OK New England style beer, perfect for the upcoming spring. How did S-33 work out in the session NEPA? Hi there. It worked out very well.
What to do with S-33 grains?

What is a S33 yeast strain used for?
SafAle S-33 is a fruity driven strain that gives a high mouthfeel and body to the beer. Ideal for Belgian Ales (Blond, Dubbel, Tripel, Quadrupel Styles) and strong English ales (ex. Imperial Stouts). It is also ideal for New England IPA’s. Yeast with a medium sedimentation: forms no clumps but a powdery haze when resuspended in the beer.
