Everything went really well, but I have a few questions if anyone can help me.
1) The dough-in water specified is 11 liters. When I put 11 liters into the grains it barely made the the grains damp - landed up with about 16 liters.
2) My OG came out at 1,059, not the 1.050 as per recipe. This seems a little high ? Maybe I miss measured the grains which could explain the extra dough - in water required as well as the higher OG.
3) Finally, when it came to aerating the wort, the aquarium pump would not work so I shook the fermenter quite violently for about 5 minutes. Can I re-aerate the wort with a new aeration pu
mp tonight or will this result in off flavours ? It is bubbling away quite nicely as we speak but I'm scared that it will use up all the available oxygen too quickly and spot fermenting.
Any comment much appreciated.
Being your first AG on a new setup, you have a lot of variables that are difficult to determine. You will figure these variables out as you get a few more brews on your system.
1. Water - Could be system dependent. You can run the math but at the end of the day, your system is different than mine so our water additions will differ. 5 liters is a bit much of a difference though but I am not familiar with your MT so not enough information to fully answer. Could it be inaccurate volume measurements?
2. Efficiency - This is your first AG and you ended up 9 pts higher. Could be that you got great efficiency or perhaps your numbers were off (volumes and/or grains).
3. Aeration - Once yeast is pitched, do not re-aerate. You should be fine. I used to do the violent shake thing and never had problems.
Your beer should be fine so relax. Besides, your first AG was on a HERMS, you are already way ahead of me!
You got a lot going on for your first AG! It took me a while just to get water volumes down!
