Well the game is afoot...
This afternoon I milled my 443 grams of home malted 6 row robust barley, then I milled 443 grams of gambrinus pilsner malt.
Unfortunately, at about this point I got distracted and forgot which grain bag had the pils and which the home malted stuff. oops. oh well, it's good and truly randomized now. Too bad it will never be un-randomized
I mashed each at 155 45 minutes (I used the oven set to 170 to maintain the temp and that worked well). I mashed in with 2.25 liters of water each so right around 4 liters/kg.
I pulled the grain bags and rinsed each with 2.5 liters of 180 degree water and let them drain while I went out to dinner. about an hour later I took a preboil gravity on each. Started the boil and added 4 grams of american liberty hop pellets to each.
Given my above comment I has assigned Sample A and Sample B.
Sample A Preboil gravity = 1.020
Sample B Preboil gravity = 1.027
I have my suspicions on which is which. I think A is the homemalted stuff. There is also a slightly less... well malty aroma to A which re-enforces my suspicion
