Sakset fra produsentens omtale av 34/70:
"This famous yeast strain from Weihenstephan in Germany is used world-wide within the brewing industry. SafLager W-34/70 allows to brew beers with a good balance of floral and fruity aromas and gives clean flavors and high drinkable beers.
... Fermentis dry brewing yeasts are well known for their ability to produce a large variety of beer styles. In order to compare our strains, we ran fermentation trials in laboratory conditions with a standard wort for all the strains and standard temperature conditions (SafLager: 12°C for 48h then 14°C / SafAle: 20°C). We focused on the following parameters: Alcohol production, residual sugars, flocculation and fermentation kinetic. Given the impact of yeast of the quality of the final beer it is recommended to respect the recommended fermentation instructions.
We strongly advise users to make fermentation trials before any commercial usage of our products.
FERMENTATION: ideally 12-15°C (53.6-59°F)"
Hva er poenget med å presse denne til å jobbe på 9 grader C - langt utenfor det produsenten anbefaler som ideell arbeidstemperatur?
Og deretter klage på at den ikke gjør en god nok jobb?

Så du holder deg alltid til produsentens anbefalinger?
Køslch gjæres i Køln visstnok på 14 grader. Sjekk hva Whitelabs oppgir som ideell temperatur for WLP029.
