Welcome!
I am a late comer to brewing, having started back in 2013. As a Chemical Engineer working in product development, I dove into the process quite heavily. I am fairly good at process questions, and know enough about chemistry to get myself in trouble...
I also like to experiment a lot and have done many scoping batches to see what I can get away with and what is important in my system. This has had it's issues, as now being semi-retired, I do consulting and do not have a ready outlet for my beer (workmates), which has slowed by brewing down quite a bit, so my inventory has grown a bit too much.
Just tapped a keg of Dunkel made three years ago. It is excellent, very mellow and almost too easy to drink.
