This is the second time that I am using a BIAB method in this 10 gallon cooler. The cooler kept the temperature right at 150 for the whole hour + time of the mash. I love it when a plan comes together.
Once the wort is boiling, I started the timer on my watch for a 90 minute count-down. My first hop addition was to be 40 minutes into the boil (the 50 minute addition on the recipe). Sometime in that first half an hour, I measured my gravity and found it to be 1.040 which was 9 whole points below what I wanted it to be.
That is far enough off that I wonder if I under-measured my grain at the home-brew shop. The other thing that I maybe should have done is held back a couple of gallons of water from the mash and "sparged" with it. Maybe things were just not going my way today.
I used large hop sacks today for my hops today. I did this for my last brew day too. I am not sure that this is a new part of my process or if I will end up not using them. I guess I'll see.
I believe I made my 50 minute addition at 60 minutes instead. I am just used to always doing 60 minutes for my bittering. I suppose I can see if the Beer Model notices extra bitterness in this beer. I sort of doubt it, but we'll see. That 10 minutes probably is not that noticeable.
At 20 minutes, I added about half a pound of extra light DME (dry malt extract) to make up for the missing gravity points. I added another half a pound at 2 minutes or so.
|Filling up the carboy from the pot.|
Just like last time, the wort chiller didn't bring my wort down cool enough to pitch the yeast, so I got the wort down the rest of the way using the ice in the 10 gallon cooler. I got the carboy wort down to about 65.
Then I pitched 2 packs of S33 yeast, shook up the carboy and am letting it sit. My OG ended up right where the recipe plans for it to be (1.053). Too bad I had to use some DME to get it there, but at least I have the ability to adjust if need be.
I just wish I knew why I was so low in my mash efficiency.
