Well my notes are not all from BrewSmith
I use Kaiser's brewlog which can be found at braukaiser.com and the efficiency analysis is also from Kaiser. The first two sheets are what Brewsmith gives me and I use them as guides for my brewday and use the brewlog to record what actually happens. I am still getting better at note taking and finding it is making me a much better brewer.
I would say the 1272 was a good option but would not recommend the 1762 Abbey II.
The balance of sweet maltiness and hops was very good. I have not done a non-deco brew of this to compare, but I can tell you the flavor profile was very similar. Some slight darkening will occur with a deco and I had my deco in the pot for a long time so I could have seen more darkening than your regular single decoction. I doubt my equipment contributed to any darkening, I have a very high quality triple ply stockpot I use as my deco kettle and heat very slowly to avoid such problems. I think I simple got more color from a longer decoction.
I can definitely say that temperature is not the source of my astringency. I have sensed it over three batches now two of which were fermented in my fermentation chamber and fermented at the low end of the yeasts range. I need to find my problem but I have ruled that out. I am going to replace all plastic and clean my brewery down with bleach, I think that will do it.
I fancy myself a good judge of beer albeit a bit lenient at times. I think that score is very accurate, this is truly a good recipe.
I do think the deco lends a nice maltiness to this beer that would not be present otherwise. I did an enhanced single decoction because I am wary of leaving the mash in the protein range for more than 15 minutes, and my schedule allowed my to do a nice deco pull and jump out of the protein rest range quickly.
I think decoctions are worth it. The intangibles in a beer can only be brought out by subtle improvements in one's process and I feel decoctions are one of the things that can make the difference. Without a side-by-side it is impossible to tell, but I think the deco works very well here.
