DetailsYeast: Safbrew S-33 (Saccharomyces cerevisiae)
A very popular general purpose yeast, displaying both very robust conservation properties and consistent performance. This yeast produces superb flavor profiles and is used for the production of a varied range of top fermented special beers (Belgian type wheat beers, Trappist, etc.). Sedimentation: medium. Final gravity: high.
Also recommended for bottle-conditioning of beers. Excellent performance in beers with alcohol contents of up to 7.5% a/v, but can ferment up to 11.5% a/v.

4.7 / 5.021 ReviewsGood General Purpose YeastI use S-33 for a variety of beers and find it to be consistent. I�?���ve used it in wheats and ales (does well in IPAs) and haven�?���t had any issues. I�?���m somewhat limited to dry yeast because of my rural setting, but I�?���ve always been happy with the S-33 brews I�?���ve made.December 24, 2015Bottling yeastGreat price for bottling yeast. Its perfect for beers that need to be aged, like Barley wine, and their yeast is depleted. I add this to the bottling bucket knowing the bottles will carbonate in the near future.January 10, 2014Cheap and easyNo off flavors and it makes good beer. It's fast acting and is done in a few days. It takes a long time to clear so I use Isinglass to help it clear. It's one third the price of liquid yeast, and I don't have to mess around with making a starter.October 16, 2013Bad attenuationUnfortunately I gave all I had to give this yeast a good start. Starter, proper aeration, time to ferment, etc. It finished fermenting after a week, but the attenuation was less than 50%. _x000D__x000D_OG = 1.045, FG = 1.020, ABV = 3.2%. _x000D__x000D_Skip this one and go with Gold's Munton.September 23, 2013Life Saver!I pitched a Wyeast activator and had zero fermentation after 3 days. I pitched an S-33, and within hours I had CO2 and krausen forming. It definitely saved my batch. I'll be keeping one or two dry yeasts on hand from now on, just as a safety measure. Well worth the small price tag!August 28, 2013good cheap yeastI like to have a couple of packs to keep around for an emergency. Maybe I have a beer that stalls, and I have no alternative. Just rehydrate this and add it and I can get an extra .005 lower gravity which is better than nothing. It doesn't clear well so you have to secondary and then use gelatin.August 21, 2013Great value, maybe misnamedI agree with others who question why this is called a Belgium yeast. Nevertheless, it's a great price for a yeast that goes into my Pumpkin Ales and Holiday Porters. Slight yeasty finish - I find it best used with fuller bodied beers.July 23, 2013Nice priceIt starts off like a race car and finishes quickly, a powerful yeast. It doesn't settle well, so you need to fine it in the secondary. It doesn't produce any fruity esters for me, at the low end of its temperature, so its a good all around yeast, especially for cider.April 10, 2013yeastThis yeast is fermenting wonderfully I am still in the primary fermentation and my abv is at 7%. WOWMarch 21, 2013Good general purpose yeastFor the economically-minded brewer, this is a good yeast. Price is right and it has a consistent performance. Since it can tolerate higher alcohol, it's good for IPA and even barley wine. I wouldn't be afraid to try this in anything from a wheat to an IPA.March 18, 2013

Browse 2 questions Browse 2 questions and 9 answersis this for a 5 gallon batch? I have read the instruction and detail sheet but I am a little confused. Thanks in advance for any help.BEST ANSWER: Yes it is for a 5 gallon batch. I use S-33 in several of my favorite brews By the way,, I do not rehydrate my yeast. I've been doing this with good results since 1994. To quote the master: "Relax . . ."
DBMWhat's the temperature range of this yeast? Is it suitable for Saison type recipes? Thanks.BEST ANSWER: The manufacturer (Fermentis) states that S-33's temperature range is 54-77 degrees F, with an optimum range of 56-68. I have used this yeast at a range of temperatures starting at about 64 degrees F for both English style ales and Belgian style blondes and wit biers. It is good for all these, and it produces excellent wit biers. This is a very reliable yeast, but it produces relatively mild esters. Your question has inspired me to eventually try it for a Saison. My only concern is that, if you want an in-your-face Saison, it might turn out a bit mild for your palate. Best wishes for blissful brewing.
