Notes

Took 1.5 G out of boil to do on stovetop
dropped to 52 in fridge before pitching

Fermentation:

The Imperial Märzen "Hybrid" SchedulePhaseDaysTarget TempAction / Goal

PitchingDay 052°FThe Cold Start: Chill to 52°F before pitching both. Oxygenate heavily for this high OG.

Primary (Early)Days 1–452°FLager Character: Keep it cool to let WLP860 drive the flavor profile and minimize "ale" esters.

Primary (Mid)Days 5–758°FThe Hand-off: Slowly raise the BrewJacket to 58°F. This wakes up the K-97 to handle the rising ABV.

D-Rest / CleanupDays 8–12 64°FThe Power Finish: Ramp to 64°F. K-97 will ensure you hit your final gravity and scrub diacetyl.

The "Pass" TestDay 13 64°FSample: Check gravity (Target: ~1.016-1.018). Taste for "slickness" or "green apple."

Cold CrashDay 14–19 33°F The Drop: Switch to an airlock (to prevent back-suction) and crash to clear the beer.Lagering6+ Weeks33°FThe Smooth-out: This 8.5–9% beer needs time to mellow the "booziness" and crisp up.
