Session Beer Series: 2012 Scottish 80/-

I'm continuing the brewing quest for my perfect Scottish Ale. I usually will brew both a 60 Schilling and then later brew a 70 or 80 Schilling each year. Well, this year I don't have quite as much time to brew, so that means larger batch sizes. I had several thoughts about what to do with this 10 gal batch:

  1. Make both a 60/- and 80/- by just diluting the 60/- in the fermentor
  2. Try another yeast experiment - I was thinking of testing WLP001 (as Jamil suggests) Vs. WLP028 (actual Scottish yeast)
  3. All 10 gals the same and then age with different wood types




Well, I selected option #3. I was inspired by Lewy over at Lewy Brewing about his new found Oak Honey Comb sticks from BlackSwan Barrels. I was looking through their online catalog and I found that they supply more than just Oak. I have been wanting to try alternative wood types for aging, so I'll post more about the wood experiment in a future post.





I have made a few small changes to my Scottish Ale recipe since last year:

  • Water: Last year I messed with my water chemistry for the first time and I over did it a bit. The numbers looked good on paper, but there was a definite salty taste. This year I decided to use Calcium Chloride instead on Sodium Chloride. And the numbers seem to be better balanced this time (see below)
  • I went back to WLP001 as I didn't notice much difference with WLP028 and I wanted to build up the yeast for a Barleywine.
  • I switched all the crystal malt over to English varieties. I am preferring the taste of the English varieties right now and I thought it made it more authentic.
