I've been looking for an Oktoberfest for my first lager. The grist bill for this recipe looked great so I gave it a shot this past weekend. The grist and hops were scaled for 10 gallons without other changes.
* Sac reset @ 148 F for 20 min
* Pulled 16 qts, thick mash, for a single decoction. Rested decoction for 20 min @ 158 F before ramping to a boil for 20 min.
* Replaced decoction for Sac rest @ 156 F fo r 60 min
* No mash out
* Fly sparge with ~8 gal @ 170 F
I collected 13 gallons to boil with the original boil schedule.
Lots of firsts for me with this one.
* First Lager
* First decoction
* First use of my new DIY Sanke mash/lauter tun
* First use of my new DIY 3-tier brew stand
* First use of my new DIY mash paddle. (This was indispensable during the decoction BTW).
The wort looked fantastic going into the fermenter, a brilliant copper-gold color. I overshot my gravity numbers (1.074) but attribute that to increased effeciency in the mash tun and decoction. I pitched a 6 liter starter of Wyeast 2633 (Oktoberfest Lager blend) and plan on fermenting for 3 weeks @ 50 F, check for a diacytle rest, then lager at 34 F for as long as I can stand it. This will be tough. I have high expectations for this beer!
