Not quite what I expected...
Got a free package of this yeast at a homebrew expo and couldn't find much info. I used it to ferment a batch and thought I would post my results for anyone interested. 3.5 Gallons, OG 1.057, FG 1.012, 79% apparent attenuation. 44% flaked wheat, 37% pilsner malt, 12% pale ale malt, 6% oatmeal, 1% light munich malt, low & slow beta sach rest + mashout. 14 IBU bittering addition only. Chilled to 68F, areated well and pitched 1 package (200 billion cells, production date 08/19/18.) 10 days in primary, racked to keg w/out finings, carbonated @52F/50 psi/24 hrs. Pale, translucent gold in color w/ a voluptuous long lasting head. Aroma is odd: anisette and maraschino cherries. Flavor is orange, alcohol and some malt presence from the pale ale and munich malts. My, (un-educated,) overall impression of this product: Not quite what I expected. Attenuation was decent. Not as clean as advertised, w/ an odd ester and phenol profile. Maybe it just needs more time to condition? So many variables. Personally, if I use a Belgian ale yeast I prefer a different and more expressive profile. Maybe it would have been better utilized in a dark ale as suggested in the advertisement? Probably won;t use it again. Cheers!

First batch with Workhorse was a winner!
I use Imperial and Omega yeasts pretty much exclusively because of their freshness and cell counts per package. I brewed an American Stout with an OG = 1.060, and it fermented to completion in 3 days at 65F.

The best thing about Workhorse is that it ferments cleanly, which allowed the flavors of the chocolate malt and roasted barley malts to shine through.

Note: as with all yeasts I use, I made a 1.5L starter, which gave me a pitch yield of about 350 billion cells.

I have harvested the yeast from this batch and will use again soon.

Excellent product
Used for a strong belgian ale with tart cherries. Started fermentation actively in 6 hours. Still chugging away after 6 days. Didn't have any issues with exploding cans like other review, but I ordered with ice packs and stored very cold. Tab on lid also didn't present a problem. Great stuff in my opinion.
