   1. Missing my numbers

      I did my first batch, and IPA (SNPA inspired) and ended up with an OG of 1.044. I figured my efficiency was just lower than expected for the recipe and that I started with too much water in the kettle (8.25 gallons in a 40qt stockpot).
      
      This weekend I decided to do a wheat beer and used a grain bill based on this recipe.
      
      I mashed at 154, mash out at 170, squeezed the hell out of the bag and boiled for an hour. I ended up with 6 gallons in the fermentor which is just right, but I only hit...

      In regards to the thread topic - For me the last thing I did for myself was to calibrate my US keggle and my sight glass. I can measure the distance with a measuring tape and calculate the volume at any time and/or I have a black o-ring pre-set on my final volume when it's at the chilled temperature. I know that evaporation still takes place after knock-out and I allow for that and I use an IC. So I tend to get my final volume each and every time. This helped me the most to get my numbers. If...

   2. Strange stuff in my aluminum stockpot

      I bought a 40qt aluminum stockpot last weekend to finally give BIAB a try. I managed to get 8 gallons to a boil with the lid on. I then let it cool on the stove and the next day I opened the lid and there is now some strange stuff all over the sides. Cloudy little 'growths' speckle the sides of the kettle below the water line. This was actually the third time I boiled water in it (to build an oxide layer). Any idea as to what this is?

      It's looking very likely that it's mineral crystallization. No barnacles ;)
      
      As for the oven, this thing is way too big! My gas stove can barely get it to a boil across two burners. Looks like I wont be able to do full volume batches (5~ gallons into the fermentor). I'll post that as a separate topic though
