4.1 / 5.023 ReviewsMade an excellent Rich German BockClean finish, no hint of Diacetyl. Just make sure after a week to 10 days you give it a couple of days at room temperature for the yeast to finish up. To make a good lager (like my Rich German Bock) you also should let it age in the refrigerator for a couple of months. Lagers are harder to brew than ales, make sure you know how to ferment them, and have the refrigerator and temperature controller. Its's not the yeast, it's the brewer, when you encounter Diacetyl.January 14, 2013A good lager yeastYou can get better lager yeast. But for the money this yeast works just fine.February 10, 2013Made a fir-spruce lager no hopsUsed this for a fir-spruce lager with corriander and sage. A hop-less brew. Turned out good. First try so maybe just luck. Fermented well.February 15, 2013Makes a good lagerMade a good crisp clean lager. Maybe not as good as some of the liquid yeast I have used, but still good. I followed the directions and the advice here and made sure to do a Diacetyl rest when attenuation was 65% complete, at around 8 days. I pitched it cool, and warmed up to room temperature for the D rest. It came out fine.April 12, 2013Only for some beersIn general i don't use this for lagers because it tends to be estery. But for some beers its a good choice. The Anchor Steam clone is a good example, where it uses a lager yeast but at warmer temperatures. For that it works well.September 22, 2013Works as AdvertizedThis yeast has consistently produced excellent results for me. And when it didn't work I can honestly say it was because of something I did wrong in the brewing process. I did a comparison with W32/70 using the same wort of OG1.047. S-23 had an FG of 1.013 while W32/70 finished lower at 1.010, and as such S-23 was a little maltier with "fruity and estery notes" making this yeast an excellent choice for Marzens, fest bier and Vienna lager. Personally I see no advantage of using more expensive liquid yeast for producing lagers of excellent quality.January 24, 2017crispthis is a great lager yeast and is underrated, very good crisp clean flavor for use in all variety of lagers..September 4, 2011Good lager yeastIt does provide a clean finish, there is no Diacetyl provided you do your D rest when the lager is 2/3 of the way done. Doing a D rest after fermentation is complete will accomplish nothing. You need a hydrometer for this reason when brewing lagers._x000D_Its a good lager yeast.December 8, 2012Should go with liquid yeastI've used both dry and liquid ale yeast and both worked fine, but with the dry lager yeast didn't have very good results. My beer ended up with high attenuation but with a sulfurous smell even after 2 months in secondary at 40 degrees F. Though this was my first lager it will probably be my last and I would say it's the yeast's fault.March 20, 2013Crisp and CleanIt's a good lager yeast, though it makes plenty of Diacetyl so make sure you do the D rest when its 70% of the way through. Also make sure you rehydrate in water, and don't dump it directly in the beer.May 31, 2013
