In an attempt to explore more nuances in the world of yeast, we have been posting yeast strains reviews along the way.  Most of the reviews have happened in an isolated instance.  What I mean is that the yeasts have been reviewed based on a particular beer and then we’ve moved on.  This time I wanted to do something a little different.

I love English Ales and have attempted to brew several different varieties.  One of my favorites has to be a Pale Ale.  This being the case, I decided to see how the same beer would act under different yeast strains.  So, I pitted this Wyeast 1099 against 1728 (the review of the 1728 will come later).  At any rate, the attenuation and flocculation levels were extremely similar.  The notable exception was a matter of 2%+/- for alcohol tolerance.

Fermentation temps were the same and the gravity of the beer was spot on, so it was up to the yeast to show the differences.

Yeast Type: Wyeast 1099

Yeast Uses: The Wyeast page names several style uses for the strain, including  Pale Ale/ESB, English IPA, Blonde Ale, Oatmeal Stout, Southern Brown Ale, Bitters (of several types), and Sweet Stout.  My beer fit right into this category, although the plan is to actually use the cake for a 1,700s style Porter.  Like the Scottish Ale yeast, higher ester levels are a consideration to keep in mind with warmer fermenting temps.

Yeast Attenuation: The stated attenuation for the beer is 68-72%.  My beer reached a slightly higher attenuation level than the website states.  I’ve seen this to be the case for several yeast strains in general.  OG sat at 1.067 and the final was at 1.016.  Either way, the amounts were fairly close and still left enough residual sweetness to suit my tastes.

Alcohol Tolerance: The tolerance of the strain was not tested by the brew that I made, so it’s hard to say whether it would exceed the stated level.  However, it had no problem at all blowing through the sugars in the beer.  Of course, most yeast companies recommend starters once levels of gravity exceed 1.070, so prepare for that if you want a really big beer.

Yeast Lag: Very little lag time occur in this strain.  I was seeing signs of active fermentation within the first 6 hours of pitching.  The pack didn’t swell as robustly as some that I’ve seen, but that was not indicative of the yeast’s capabilities.  The lion’s share of the yeast work was complete within two days with some activity for several days following.  Clearing took a bit, but flocculation was good.

Overall Performance: I’m happy with the qualities I got from the beer.  As I drink it, I realize that it’s not particularly malt emphatic and not heavy on the esters.  However, the subtle flavors and longevity of the flavor make up for robust qualities.  The finish was dry and honey-like on my palate, and I’m looking forward to how this beer develops.
