Brown Rye (starter beer)

As I wrote about recently, I brewed a lot of beer with my dad this summer on his beautiful new all-electric setup.  He's been trying out a number of recipes in different styles he's found online--a frequent starting point for me as well--as well as working on scaled-up AG versions of beers I designed when he was doing small extract batches in my folks' former home.  Over the summer we'd trade off between us on the brew planning.  Having sought to finally brew a kölsch for some time--most recently this spring--that was my first choice.  Brewing such large volumes (11-12 gallons) and not having a stirplate on hand at the time (my dad built a nice one soon after this) meant that before the main brew must come a starter beer.

As it happened, my dad had a big Belgian/Trappist-style beer planned and needed to propagate yeast for that as well, so we brewed six and a half gallons of low-gravity wort to split between the two yeasts.  In some sense it was also a cleanup beer, finishing up some odds-and-ends grains in the brewery.  However the main malts, Munich and rye, I chose very intentionally, aiming to get a lot of richness out of this smaller beer.  Coincidentally this ended up encompassing long-term plans I've had to brew a Belgian rye table beer.  My original aim was for a red colour, but it ended up solidly brown.  Out of the two beers produced, I prefer the Belgian iteration, the kölsch yeast characteristics not really meshing well with the strong malt flavours.  In the end, though, we had large yeast pitches for both big brews and a couple interesting experimental beers to try.
