Yeah, I should've given a bit more context.
I'm at the tail end of my lager season (no temp controls, but basement should still be good for a few weeks) and I have some lager slurries [yeast cakes?] that I've been using all winter with great results. S-189, and Diamond, both on about the 4th or 5th generation, I don't remember. I wanted to get one more beer out them before moving to "ale season" and dunkel is a style I like brewing and drinking.
I have some Candi Syrup on hand, and I don't think I'll be making any Belgian beers this year, and maybe not next year either. I thought I might make a dubbel or Quad or Belgian Dark Strong, etc., that's why I have it, but I won't be brewing during the months that my basement temperatures would be ideal (probably out backpacking for a couple of months).
Sure, the Candi might still be good in the fridge until 2025, but since I'm going dark malty munichy lager on my next brewday, I was thinking I might kick it up to a higher OG with the syrup, or add it to the fermenter later, or... I don't know. Curious to see what would happen.
I guess I should just do it and report back if it worked out or not. Just wanted to see if anyone has gone that direction and whether it is probably going to disappoint. Worst case scenario, I have a Dark Strong Lager or what-have-you, that will probably taste good enough when I'm off the trail and haven't had any beer for a few months.
