This yeast is a beast!
Holy crap! I added one dry package ( I did not have time to make a starter or even rehydrate, which could be considered a rookie mistake, except for the fact that I have been brewing for 40 years) to 6 gallons of a 1.59 OG cream ale at 64 F. Within 6 hours, it was fermenting actively, and within 18 hours, it had blown a liter or more of krausen into my blow off set-up. It probably would have shot a standard airlock into outer space.

It's only been 24 hours since pitching, and I'm still in shock. I'll update once I've had a beer this yeast has produced.

Easy to use - Produces Fast Clean Lagers
I have been experimenting with this yeast by brewing a standard German Pilsner and then chilling it down to 50F before pitching two packets (properly rehydrated), oxygenating, and then holding it as low as I can with my cooling setup. It generally only can stay around 55F-60F for about 2 days before the ambient Summer temperatures raise it up. But by then, the yeast is out of growth phase and into full kreusen, where it ferments fine and doesn't produce any off flavors. I then hold it around 65-67F until fermentation appears to be near finishing, and then raise to 70-71F for two more days before fining with gelatin and then cold crashing prior to kegging. Amazing lager-style beer in less than 2 weeks. Lagers in the keg and eventually tastes indistinguishable from a traditional lager, as least to my keen palate. I love this yeast.

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.

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.

great yeast
Very consistent, dependable yeast. Starts in 12-18 hours and attenuates greatly. Low sulfur and diacetyl levels

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.

So far, so good.
I'm in secondary fermentation. Weather has been hot but it seems to be making a good lager even in the mid-60's

How many ounces is this?

BEST ANSWER: 11.5g = 0.405 oz
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.
