Taste Notes: The absolute best Oktoberfest that I've tasted, this has everything that I've looked for in an Oktoberfest:
An amber beer with great smell and flavor. Plenty of the malty flavor expected from a Marzen type beer, with a slightly sweet accent.
Full-bodied, a real nice balance between malt and hops, with a crisp, clean finish.

Notes
Fermentation -
I fermented at 50° for 9 days using White Labs German Bock Yeast WLP833, (do not deviate from this!) on day 9 the gravity level was 1.030.
Diacetyl Rest -
I removed from cooler and brought it up to approx. 62° for 3 days.
Lager -
I returned the carboy back to the cooler which was now at 30°, the beer slowly cooled to 27° - 30° over two days and lagered for approx 8 weeks.
Finishing -
I add 1 packet of unflavored Gelatin hydrated in 1 cup water that I heated between 150° - 160° (DO NOT GO OVER 160°), stirred well and put the over flow tube back in and close the cooler. It remains there for 2-3 days. At this point, I rack over to my bottling bucket, add the priming sugar, bottle and cap.

**Brewers Note:
Due to concerns of the yeast not being viable enough to carbonate after 8 weeks of at lager temps, I added 1 gram of Lalvin EC-1118 yeast, hydrated and added to the bottling bucket at the same time that I add the priming sugar, this yeast will not impart any flavors or characteristics to the beer, it simply ensures a successful carbonation, furthermore, there is no risk of bottle bombs using 1 gram per 5-6 gallons.
