I seem to think Nateo posted it on his blog a long time ago but I haven't seen him around these parts in a while.
I'm still alive! But yeah, real life has kept me pretty occupied. I haven't had time for brewing since maybe June.
It's been a long time, so I can't remember the details, but from talking to some German brewers, apparently there is a "traditional" brewery over there that still uses the old techniques. IIRC they did a decoction mash pretty much all day, then a 3-4 hour boil. If I remember the name I'll post it.
Just FYI, most pro and hobby brewers in Germany think decoction is wasteful of time and energy (it is) and kinda silly. However, they love step-mashes with at least 3 steps, although 4-5 are typical, which I think is also silly.
FWIW I think most of the allure of decoction is merely the fetishization of the popular conception of German brewing. It's kinda like foreign branding, or the nonsensical use of umlauts, a la "Haüs Of Growlers."
