DetailsFermentis Safale K-97 is a German ale yeast selected for its ability to form a large firm head when fermenting. Suitable to brew ales with low esters and can be used for Belgian type wheat beers. Its lower attenuation profile makes for beers with a good mouthfeel. This ale yeast works at a wide temperature range between 12-25°C (53.6-77°F) but ideally between 15-20°C (59-68°F). Highly flocculant.

4.5 / 5.02 ReviewsThis yeast is quite strongI have now made two batches of Kolsch beer using this yeast. I had others taste my beer against a commercial variety and have been told it is hard to tell what was homebrewed versus the commercial variety. I have not followed the directive to make a starter or rehydrate first, but this yeast is so strong, I have had to swap my bubbler airlocks for a hose to a bucket filled with water, because the yeast takes off strong and has pushed foam through my airlocks. The beer produced is very clean and is a very good example of what a Kolsch should be.February 4, 2018Purchased

I would recommend using it with batches that are about a gallon less than usual, or with fermenters with a lot of headspace. That being said it established and began fermenting quickly.April 23, 2016
