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 Reviews$2 for yeast. Rock star.I just wanted some el-cheapo yeast to make a bucket of proper cider. S-33 delivers. A touch "yeasty" in the finish, but not bad. I wouldn't say this is a clean yeast. But it has no obvious off flavors except a bready and yeasty character._x000D__x000D_It's light speed at finishing. It churned through my cider, starting at about 1.058 dropping it to 1.008 in 60 hours at 68F. Direct pitched into a 4 gallon batch of cider. _x000D__x000D_I have a 6 gallon batch of 1.060 brown ale that I pitched a rehydrated packet into. Krausen was popping by 6 hours, rocking by 12 hours, and the bulk of the fermentation has finished in 48 hours. Also at 68F. I suspect you could put 12 pounds of meat, a gallon of kerosene, and a pair of shoes into a fermenter and s-33 would chew through that in a hurry._x000D__x000D_It doesn't play around. A decent yeast for the price. _x000D__x000D_Just FYI, there is ZERO belgian to this. I have no idea why it's marketed as a Belgian yeast. Yes, Fermentis says it is. But what if Fermentis said this made your beer taste like gravy and bacon? Would we just trust that too? Ditch the silliness about it being Belgian and just call it a nice soft English-style ale strain.October 1, 2012Good productVery quick brew with this yeast. Completes in 3-4 days.October 16, 2012good, all around dry yeastIf you are looking for a cheap, fast, and all around decent dry yeast this is the one! I've used it at a variety of temperatures and it always performs well-very fast fermentation and generally no distinct or off flavors contributed to the final brew. if you're brewing high gravity beers recommend either using two packs or creating a starter.November 5, 2012Nice 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, 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, 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, 2013Cheap 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, 2013Bottling 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, 2014awsomeworked really good,started fast did its job and finished in 4-5 days. will use againApril 10, 2012Great yeast!This is my favorite dry beer yeast out there. Iuse it in all my Belgians, and it creates a very nice flavor. Leaves a big, well rounded mouth feel as well as nice spice flavors, especially if you add is darker malts and adjuncts. Highly recommended.November 27, 2012

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.
