A pleasant surprise
Had to use this yeast for the first time as the LHBS was out of liquid yeast. I'm very impressed and like it better than 34/70. Made a very clean helles that cleared quickly. Great attenuation w/ FG of 1.011. Repitched into my second helles and it's now done at 1.011 too. Fermented in the mid 50's for 10 days and warmed up to 62 for a few day.

Great for Pilsner
I make lagers in the winter when the temp in parts of my basement drop to 54 F, about right for primary fermentation for this yeast. I use two packs for a healthy start. After 9 days a solid day at 62F gives a decent diaceytl rest. Then to my garage for lagering at 44-46F for 3 weeks. To the bottle for 4 weeks at 60F. Every one I have made has turned out clear, dry and crisp. I re-use the secondary floculation for next batch. Great taste for a dry yeast and never lets me down. Try it.

Works fast
Used 2 packages together for a Schwarzbier. Visibly active fermentation less than 6 hours after pitching at 72 degrees, and at 12 hours the carboy headspace was full of foam. Compare to dry ale yeasts I've used, these packages took about an hour of sitting in 72-degree water to turn to "cream", which is easily twice as long as the ale strains, so be prepared to be patient while it rehydrates. Also, go to the manufacturer's website and have the .pdf file of the rehydration instructions handy since the ones printed on the package lack a lot of detail.

Great for Maibocks
Used 2 packs of rehydrated S-23 in a 1.070 Maibock fermented at 52 degrees and it tastes great. Attenuation was 74%. Brewed it on 3/10/2012 and tapped the keg 5/11/2012. I will definitely use this yeast again. Don't discount dry yeast until you have given them a shot.

Good stuff
Works great when you can't keep a lager temp (55 or so)and need to ferment around 68, but can still work at a higher temp if you have fluctuations.

very good yeast
I used this strain of yeast for the first time, and it was referred to me by my supplier. I did an all grain brew (crystal 45) was the main ingredient. I found that it was a great performer but I had an 18hr lag time (but this was my mistake) but once it did kick in, it finished in 10 days with excellent clearing and a real clean taste, it really brought out the malt flavors. Very good on sedimentation, fermented at a constant 20-22deg C. I will be using this one again.

very good
The day before brewing, I tossed 1 pack into 2000 ml of wort @ 1042 o.g.. The starter was held at 75 degrees. The next day I had a very active starter. The boiling wort was pumped through a Therminator, which dropped the wort temp to 60 degrees. Then I pitched the yeast into 9 gallons of 1058 o.g. wort. Within 2 hours, the blow off was pumping out CO-2. The yeast worked strongly for 5 days @ 70 degrees. I racked the beer in 10 days. I lowered the temp to 35 degrees for 25 days. I racked the beer into a 1/4 keg along with 2000 ml fresh wort at 1058 o.g.. Six weeks @ 50 degrees, then l tapped the keg. The beer was blonde/golden, malty, pleasantly dry, thick white head, tight bubble, with a nice clean taste and finish. So far, I used 4 packs, in pilsner wort, with consistant results. Try it!

How many ounces is this?
E C on Feb 18, 2016
BEST ANSWER: .40 or 4/10ths of an ounce.

I do not understand why this is a concern.
It should be understood that given enough liquid food and time a virtually
unlimited amount of live yeast can be the result.
If I used this for the Oktoberfest recipe kit, would I need two packs or would one be plenty for a 5-gallon batch? Also, has anyone had experience with this strain fermenting in the mid 60's for a temp?
Ed D on Jul 1, 2016
BEST ANSWER: One should do fine, be sure to aerate really well in that situation though to give the yeast plenty of oxygen. S-23 does a pretty good job at temps around 60-70 actually, they say it will work up to 72.
