Til info så er White labs Wlp099 også diastaticus.
Gikk og sjekka hva de skriver sjøl:
"
**This strain has been genetically typed in our lab using polymerase chain reaction (PCR). Through this genetic testing, we have determined WLP099 Super High Gravity Ale Yeast to contain the glucoamylase gene (STA1), a potential indicator of S. cerevisiae var. diastaticus. Brewers yeast are natural hybrids, which make it possible for certain strains to display elements of the STA1 gene. These strains have the ability to utilize some dextrins (unfermentable sugars), resulting in higher levels of attenuation than what is considered typical.
At White Labs, we do everything possible to detect for undesired organisms within our process and cultures. The strains we carry with known var. S. diastaticus genetics have been researched and validated to perform without excessive over-attenuating, which is possible through our nearly 25 years of experience paired with internal and external fermentation data.**
Det blir jo et akademisk spørsmål om 099 er en diastaticus eller ikke. Det viktige er at den har den egenskapen som er skummel ved diastaticus.
Det er interessant at de sier "The strains we carry with known var. S. diastaticus genetics ... ." Så de har flere. Skulle vært interessant å vite hvilke. Men jeg regner med at teksten ovenfor da vises ved alle.
