Yeast and Fermentation / stir plate vortex
« on: February 19, 2010, 08:17:46 PM »
First homemade stir plate in a cigar box.  Cost: $5 (the 1" stir bar).  Computer PSU fan with hard drive magnet.  Powered by another computer PSU converted to a benchtop PSU.  Current output voltage to fan is 7V (10V is too fast; the stir bar spins off).  Does this look like enough vortex for a 2L sample (in a 1gal. jug)?

And this vortex for a 1L sample in a 1L flask?

Beer Recipes / Sam Adams Noble Pils clone
« on: February 12, 2010, 10:49:11 PM »
So I tried this beer a while back at their R&D brewery and I loved it.  Trying to clone it.  A 5-gal recipe sounds great.  From their web site, we find that they use 2-row Harrington, Metcalfe, and Czech pilsner malts.  And for the hops, the typical Noble variety: Hallertau Mittelfruh, Tettnang Tattnanger, Spalt Spalter, Saaz, and Hallertau Hersbrucker.  No idea how to partition the grain or when the hops get added in the boil.  As you can probably tell, I'm fairly new to this.  But, I've hacked a first recipe.  Anyone care to steer me in the right direction?  Thanks!
