I just showed my wife this post and said "See honey, I'm not that bad!" I would love to have three stir-plates or even a nice work area like you have for brewing. How big is your fermentation chamber/fridge if you're doing three lagers at the same time?
The stir plates are $42.00 each on homebrewstuff.com (cheap). The work area is a $50 laminate counter top from Lowe's on top of half sized shelving unit (as in you can build it fairly cheap and the laminate can be sanitized!).
I use a chest freezer with temp controller that can fit exactly three 5 gallon buckets as primaries. Then I have a larger chest freezer that can fit exactly six 6 gallon carboys for the lagering stage. Then keg them in cornelius kegs and into the old converted refrigerator (shelves removed and wooden bottom built full length/width. Fits 4 soda kegs with some extra space on the side.
Stepped up to 2L per starter and I'm attempting the FOAM stoppers from Austin Homebrew - fully sanitized with OneStep - awesome idea compared to aluminum foil. WOW that WL Zurich Lager is flocculating like a BEAST in there!!! It's basically blowing yeast chunks!
This vial was a BEAST in both the 1L (1st gen) and 2L (2nd gen) starters... And it was dated Best By 2/14/2012 but just put into service 3/4/2012. And dang that stuff stores up some CO2 in the vial - it sprayed all over when I cracked the vial open...
Wait, your 1L starter and 2L starters looked to have quite a bit less than that volume filled with starter+yeast. if I have a 1L flask filled to 500 mL I'd call it a 500 mL starter, not a 1L starter. Have I misunderstood something along the way?
