Simplicity
No muss, no fuss, no starter no need to re-hydrate. Short lag time and fast efficient fermentation. Have been using this for years with excellent results.

A workhorse....
We use this yeast in our brewpub here at Cave Mountain Brewing Co. in Windham NY. It ferments quickly without off flavors even when ferment temps get in the high 70's and low 80's. Homebrewers with problems with high ferment temps should try it if their looking for a "house strain". Can be reused at least 5 times without changes to it's profile.

reply to William H negative review
William H...the yeast didn't ruin your beer. You did! :-)70 degrees is too warm for this yeast if you want a neutral profile. You should be fermenting near 64 degrees (fermenter temp, not ambient temp) if you want a clean profile.One packet is enough for a beer of 1.050 or less. If you brewed a higher gravity beer you may need to pitch more.Double check your brewing practices before you blame it on the yeast! ;-p

Follow up on previous
Ok, I previously reported that the yeast blew off the blow off tube. Well in only a couple days fermentation of my Dry Irish Stout was complete, racked to secondary for another week and half then to my corny keg. Tried beer just before Christmas and wasn't ready, but only days later and it is spot on. From Primary to drinkablility in less than 6 weeks. Very impressed with this yeast. May never buy Guinness Pub Cans again...

Pitched porter on top of..
Ok, two previous reviews, and in my last I said I was gonna pitch a bourbon barrel porter on top of this yeast cake. Well I did, only modified recipe to use 100 proof rum infused with 3 vanilla beans. That was 8 months ago...Beer came out tremendous. I bottled them in 22oz bombers and have been giving them out sparingly to special people. Trying to save some for Christmas. This yeast is a beast.

I recently used one packet of this to make a 5 gallon batch of cider which came out great. Does anyone have any suggestions for scaling this up? Lets say I wanted to do 250 gallons, would I need to use 25 packets or the equivalent in larger packaging? Do yeast cultures multiply at a rate which would require fewer packages of dry yeast for a larger batch of cider? Thanks.

BEST ANSWER: I agree with Kevin, I think the packet count would be somewhere between 40 and 50 (take a look at the pitching rate calculator at http://www.mrmalty.com/calc/calc.html) so a starter would be one way to go. I think it is a 4 liters of slurry which is a bunch of slurry. I'd likely do a series of starters to get to that (1 liter, 2 liter, 3 liter, then 4 liter, etc.) Have not done that with cider, nor with dry yeast though so I'd ask around a bit. Might be worth looking at whether you can buy a larger pitch than the small packet to avoid the risk of contamination that the starters would present.
I'm wanting to brew a pumpkin ale recipe that calls for English Ale White Labs WLP002 yeast but I'm worried about shipping with it 95 degrees in south Mississippi. Would this be a good dry substitute?
V A on Aug 4, 2016
BEST ANSWER: Yes! S-04 is a great substitution for almost any English variety of yeast.
