Who says you can't have a kick-a*s lager in 2 weeks? Review by David
For 5gal Octoberfest I began with a 1L starter of this yeast which I then stepped up to a 2L starter. Pitched slurry into 50F wort (Pils, Munich, Vienna) and fermented at 50F for 5 days. Then I brought fermenter to room temp (70F) for 7days and racked to keg. Cold crashed to 30F, fine with isingless (heresy!!!) and force carbonated, let sit at 30F for two days and then brought up to 48F to serve. Fantastic! This beer will not last until September; must brew a second batch soon. (Posted on 8/23/14)
Good yeast for Oktoberfest Review by Patrick
The yeast worked great. I may have lowered the temperature too quickly during the 2nd phase of fermenting, which I've heard can shock the yeast. I didn't have any problems with it, though, and the beer turned out great. (Posted on 1/4/14)
Brilliant yeast for Oktoberfest Review by Brett
I used this yeast for an all-grain Oktoberfest, no starter. Fermented at 55F for 2 weeks, including diacetyl rest at 60F for last 2 days. Lagered at 45F for 4 weeks before bottling. Slight sulphur after one week in bottle quickly disappeared.
Arguably the best beer I have ever made. Clean but complex, malty and sweet, just enough hops to balance. Unfortunately my wife is besotted with it and I haven’t got to drink much of it myself! Will definitely use Wyeast 2633 again. (Posted on 10/28/13)
Excellet lager strain Review by James
Loved this yeast. I made a Vienna Lager with it and it is malty and clear all within about 4 weeks. Good attenuation. I made a 2L starter and fermented at 48F the first 2 weeks. The last week I raised the temp to 60. Some sulfur production but it goes away quickly. (Posted on 9/4/13)
