I should check in here more often...
Late to the party, I'll offer my .02 on the recipe and summarize some impressions:
- I'd hold back from the 80 IBU mark in order to allow some room for the bitterness provided by spruce tips (is spruce still part of the plan?)
- 1.5 lbs/BBL (15# total usage) spruce tips at knockout or during fermentation seems reasonable (maybe 7.5# ea?)
- I like Centennial for a mid-kettle addition, but my personal preference is to showcase more resinous and assertive late kettle and dry hops in a red rye. Floral and grassy hops tend to get lost in the mix. This is especially true for Cascade, but entirely subjective - perhaps you had intended a more subtle hop profile, so do as you please
- The example below uses mostly Sultana(Denali) and Chinook. These should both be complimentary to spruce
- If Sultana is a pain to source, another resin-forward hop would work, though I might adjust dosage. (Idaho 7, Columbus, Nugget, Apollo, Warrior)
- The recipe makes a number of assumptions about Transplants' brewhouse, but is geared toward even numbers, full sacks, etc. while approximating your percentages. Batch size here is post-boil kettle volume. I may be off the mark vs. their typical numbers, but hopefully this will save them some work anyway
- I've tried not to mess with the aforementioned malt percentages too much, but 5% Roasted Barley would put the color past 30 SRM. For beers which I don't want to taste roasty, I keep this contribution under 1.5%. Blackprinz/Carafa/Midnight Wheat would all work too
- This OG yields 7% ABV @ 82% ADF (FG 1.011). Adjust as needed to compensate for Transplants' typical results with 001 at this mash temp
- 14 SRM definitely leaves room to go darker, but "red" is somewhat ambiguous. 20L Munich could be used instead of 8L for a touch more color if desired (a.k.a. dark Munich/melanoidin/aromatic, etc.). Alternatively, use 1.5 bags or 82.5# C60, which meets your 10% usage mark and gains about 1.5 SRM, increasing the color to 16 SRM. This recipe prioritizes your initial color spec instead of malt percentages:
