The recipe was an 5 gallon AG kit from brewmasters warehouse (anonymous blond ale aka Centennial blonde ale). Seemed like a good straight forward kit to try as my first attempt at BIAB. I've been doing extract kits for a few years and generally liked the end product but they seemed to be lacking something. Also noticed that I couldn't seem to make lighter colored brews with the extracts and I wanted to have a batch that I could keep around as a "quaffer."
Anyway the brew day went well with only the typical stumbling blocks so that is a success in my book. I recently purchased a new 10gal brew pot but was disappointed to find that it only held about 9.4 gallons. This lack of volume pushed my mash to the limits of this pot. Looks like a new pot may be on the future wish list but it will work for now. I also seemed to be boiling off a lot faster than anticipated. Not sure if it's the pot (14"ht x 15"dia) or burner (105k BTU) but I ended up cutting the 90 minute boil down to 70 minutes. Not bad just unexpected.
Results:
My recipe had the following
7.0 lbs 2 row brewers malt
0.75 lb 2 row carapils
0.50 lb caramel 10
0.50 lb weyermann vienna
From the write-up I should have been trying for an OG of 1.045 so I'm glad that I came in as close as I did. Not too concerned about hard numbers as I tend to round off too much but I do want to get all I can from my process.
I mashed a bit too high and had to stir down to 155F for 90 minutes and did a 10 minute mashout @ 170F. Seemed like I held more wort in the grains than I was expecting. I hung and squeezed the brain bag like a bad milk cow for 15 minutes and did manage to recoup some wort. My pre-boil volume came in between 6.5 and 7 gallons which combined with my fast boiling cut me short.
I ended up with a pre-boil gravity of 1.032 and a post boil gravity of 1.041. Not sure but it seems close to me. All in all a good day.
In hindsight I think I could have gotten more water in the pot. It seemed a lot close to the top at the time but it looks like I still had room from the pics.
