I tried this recipe recently. I added an addtional lb of the smoked grain as suggested. Just racked into secondary last night and taste tested my hydrometer sample... The smoke flavor was still extremely subtle. To be honest, it was almost non-existent. Now, in comparison, the Rogue smoke ale only has a subtle smoke aroma/flavor too. It still had decent flavor. Not necessarily my cup of tea, but I brewed it for my Dad anyway, so I am sure he will enjoy it. Came out to about 5.37% alc, which is a little low for my liking. I’m more of a DIPA or Belgian Dubble/Quad type of guy, liking my beers ranging from 7%+ with robust flavor and aroma.
If I were to brew this recipe again, I would probably substitute a lb of the 2 row for an additional lb of the smoked malt. That would bring the total smoked malt up to 3 lbs, but keeping the same overall total grain lbs the same.
