Any further thoughts on this brew? How did the GU/BU balance end up? How did it age? Any changes you would make?

I know this one is a little old, but I'm curious. If I ever get around to brewing any lager, this style would likely be it. So, I just plugged this recipe into Beersmith and got pretty close on the numbers with the glaring exception of yeast starter size. Beersmith recommends a 7.4 liter starter with 681.3 billion cells. Uh... really?

Brewpastor - I did rebrew this last season and lowered the OG to about 8% ABV. Other than that, everything stayed the same. I'm actually drinking (and loving) that version now, and have all the ingredients to rebrew it this season. Reason for lowering OG/ABV was to reduce aging time so hop flavor and aroma was fresher. I can drink it younger and it still pops with all those hops. I think this would take well to some sort of dry hopping, but I really never do it.

As far as a starter, 7.4L is excessive. Yes, it is a large lager and you WILL want a healthy starter, like 2L volume (that's at least what I do). Then again I also hit my wort with O2, as well as always always use some sort of yeast nutrient. Additionally, to have a sucessful brew you are going to want to do a 90min boil and chill the worth quickly afterwards to head off DMS.

Thanks Sirsloop, I'll adjust the grain bill to hit that 8% and put this on the list. Also, I forgot to ask, do big lager fermentations generate big kraeusens like ales, IOW, do you need a blowoff tube?
