My set up is a 15 gallon hlt, 10 gallon rubbermaid cooler for MT, and a 15 gallon boil kettle.
My dead spaces are 4 cups HLT, 3 cups MT (without tipping the MT), 6 cups BK.
I brewed up a Mojave red recipe, posted here on HBT. With a grain bill of.
82% 8lb 4oz American Two-row
5% 8 oz Caramel/Crystal Malt - 80L (Franco Belges 80L is best)
5% 8 oz Caramel/Crystal Malt - 40L
5% 8 oz Caramel/Crystal Malt - 60L
2% 3 oz Melanoidin Malt
1% 2 oz Carafa II special
0% 1/2 oz Roasted Barley - 550L
Mashed at ~152
60 mins 1.0oz Palisades pellet 8.1
20 mins .5oz Sterling leaf 7.0
10 mins .5oz Willamette leaf 4.5
Rehydrated pack of US-05
Dry hop 7 days .5oz Cascade leaf 7.0
I put the data into beersmith and it called for
3.04 Gallons for the mash
3.97 gallons for sparge
Total of 7.12 gallons of water for a boil quantity of 5.7 gallons into the boil kettle.
I measured out 7.5 gallons of water using a gallon water jug. While I was mashing, I used the gallon jug to measure out an approximate 5.7 gallons into the boil kettle. Which put the cold water level at the closed off port of my BK. It gave me a reference as to where the wort level should be.
After mashing and sparging, the level was to the same point where the 5.7 gallons of water was measured out previously.
I started the 60 minute boil right after hot break, probably took 15 minutes to reach boil.
After my boil, hop additions, etc. I ended up with this. I am guessing 3 gallons with a gravity of 1.058.
I ended heating 3 gallons of water in my HLT to 168, and running it through my grains again. The third runnings had a gravity of 1.010. I did a 20 minute boil, cooled it, then placed it into the fermentor with the initial 3 or so gallons. placing the total gravity to 1.040.
I am starting to think that due to the size of my boil kettle. My boil off is higher. The kettle is 18 inches across, 15 inches deep. Rough circumfrence of 57 inches (measured using a tape measure).
How do I figure out my boil off?
