Side by side
Had a process problem with our favorite double black IPA recipe and crossed my fingers as I used 1056 for 5 gallons and 090 for the other 5 gallons. Though neither turned out as well as usual, the 090 had far fewer off flavors than the 1056.

Better than WLP001
I used it for an imperial black IPA and a black session IPA. It fermented the imperial from 1.102 to 1.030 in two weeks, actually mostly in the first week, at about 70 F. The session IPA went from 1.048 to 1.012 in one week. Upon first taste the SD super yeast is very neutral and does not accentuate either hops or malt.

Chews through IPA's without issue.

yep yep yep
don't get the idea that this will ferment any beer in 3 days...it's not THAT fast but it will ferment 2-3 days faster compared with 002. The flavor is almost identical ( i've done side by sides) with 002 but the main difference is flocculation, it will clear without finings within a few days unlike 002 which can take a week or two. If saving a few days is important to you (i think this strain is going to be more attractive to commercial brewers where 3 days is a big deal) then go for it!..

Ravenous Beasties.
I love it when a product delivers the goods as advertised. I made a starter with this yeast 24 hours before pitching. I had visible activity 2 hours after pitching, and by the 8th hour it was blowing chunks out the blow off tube. Fermentation was pretty much done in about 60 hours. This IPA got off to a great start and will hopefully have a great finish as well.

Clean and fast. Incedibly vigorous fermentation by 24 hrs (though I do make a 1/2 gallon starter). Blow-off tube a must; krausen will overwhelm an airlock and make a gross mess.

Faster fermentation and faster flocculation
At the advice of a brewing buddy of mine, tried this yeast vs Wyeast 1056. Faster fermentation time and dropped clear in less time than 1056. Not to mention I like the vials White Labs gives you. Great place to store yeast for future brew days.

Created a starter the day after the use before date expired; pitched the next day and got activity within 4 hours. Fermented at 70-75 degrees and it was over within 3 days. Went from 1.067 to 1.014. I had 2 gallons pitched with Safale-05 to do a comparison and the SDSS was much more clearer when they were done. No odd flavors contributed to the higher fermenting temps. Washed the yeast to do some more later.

Does what is says
Fast, Clean and Dependable ferments. I have my ales too the keggerator in quick time. No off flavors.This is my Go-To yeast for neutral ale's.I've done over a dozen brews with this.

Will definitely use again. Had great reaction within 36 hours and stayed active. Recommend this strain.
