Description
SafAle W-68 11.5g – dry yeast for German wheat beer
Fermentis SafAle W-68 is a yeast strain from Weihenstephan, selected for brewing classic weissbier and other German wheat beers. It gives the typical phenolic character of clove and pepper, and rich fruity and floral flavours with banana. The yeast suits a wide range of wheat-based beers and fruity, spicy styles.
W-68 ferments quickly and normally reaches about 80 % attenuation within 4 days. Sedimentation is medium: the yeast does not form clumps, but gives a powdery haze when it is in suspension in the beer.

Frequently asked questions about SafAle W-68
How many packs do I need for 20 litres?
The recommended dosage is 50–80 g per 100 litres. One 11.5 g pack therefore covers about 15–23 litres of wort.
What temperature should W-68 ferment at?
The ideal fermentation temperature is 18–26 °C, with 20 °C as the optimum. Keep the temperature stable, because swings and too high a temperature give more esters and can cause off-flavours.
Why does the wheat beer turn hazy?
W-68 has medium sedimentation and gives a powdery haze in the beer. That is typical of weissbier, where the haze is part of the style.
