This past Saturday I did my 2nd All Grain batch using my SQ14 burner and Keg converted Keggle.
The kit was a Victory Hop Devil kit from Austin Home Brew Supply!
As you will hear in the video, I was off on my #'s again!
When I did my first AG batch, I had NO idea how much boil off I would have with this setup. Since I wanted to end up with 5.25 gallons into the fermenter, I started out with 7.25 gallons when I did the first batch and only boiled off 1 gallon in an hour.
When I did this 2nd batch, I ended up with 6 gallons after the 1st runnings and double batch sparge so I figured I'd boil off a gallon again and end up with 5!
I ended up with 4 gallons after the 60 minute boil so I added 1 gallon of water to get to 5 in the fermenter.
I did try and keep about the same rolling boil as I did on the 1st batch.
The only 2 things I can think of is on this 2nd batch, it was a much cooler day, the wind was up so I had made a wind shield for the burner. My after thought is that the more direct heat using the shield caused more boil off?
Also, on my 1st AG batch I used 1 gallon paint strainers for each hop addition. Separate bags for each addition. The 1st batch I did had 3 oz of hops total.
This 2nd batch had 4 1/2 oz of hops total and I used 1 five gallon paint strainer hung over the side of the keggle and just added the hops when called for.
I guess I never realized how much hops expanded. After seeing how much was left over in that 5 gallon paint strainer, and I'm also wondering if the 1 gallon strainers allowed for enough utilization?
So was it the hops that absorbed more wort during the boil?
Was it the more direct heat?
Was it because there was only 6 gallons pre-boil compared to 7.5 and the smaller volume caused more boil off?
Or was it a combination of all of that?
Also as you'll hear in the video, I missed my OG.. should have been 1.068 and I ended up with 1.052. Dang it! ha
EDIT: Forgot to mention one thing.. Seems like when I do my dough in and stir stir stir, I get inconsistent temp readings on each side of the 52 qt coleman xtreme. Like it'll read 153 on the left side and 150 on the right side... And again I stir quite a bit.. Anybody else see this or am I just being too anal?
