I asked recently about high mash temps, in another member's thread, but still had some other questions about my first all grain. I didn't want to thread jack that person's topic, so just thought about doing a new one here (thanks to those who answered and gave advice, much appreciated
I did the BIAB approach using my Bayou Classic 10 gal pot with bag and steaming basket. The brew was a Fat Tire clone.
I used a calculator app on my phone and after putting in the info, it came up with 159F strike water to do a 152F mash temp. I did this, but when I poured in my grains, stirred, then check the temp, I got 156. Oh, brother!
I stirred for 10 minutes and the temp dropped to 153. I put the lid on and covered with a thick blanket, and set my timer for 60 minutes. I noticed the temp dropped one degree over 35 minutes. I don't know if you are supposed to constantly stir through out the mash, or just the first few minutes and then leave it for 60. I got to reading and saw where some suggested stirring, so which one is it? Stir through out the entire time, or just to smooth out any dough balls and leave covered for 60?
After I mashed out (170 for 10 minutes), I took a 2 quart pitcher and just filled it up about 3 times and dump it back into the kettle. I don't know if this is the proper way to vourlaf, or if that's really needed, but I done it anyways. My wort still looked a bit cloudy. This was having the basket of grains sitting on an oven rack above my kettle when I done this.
After that, I took a gravity reading and got 1.040. I also had 6.5 gallons in my kettle. Since this was pre-boil, I dumped the sample back in and fired up the burner and did my hop schedule. I took another reading of the wort after I cooled it down and got 1.042. This was with 5.5 gallons of wort instead of 5. Should I have boiled off the half gallon, or is this ok? This clone was from NB, so is it a fair assumption that the OG should match up with the extract version? The extract version shows an OG of 1.052, so I'm worried I screwed the pooch on mine.
Apparently, I'm losing a gallon instead of the 1.5 gallons I previously thought. Now that I know, would it be better to boil down first, then do the hop schedule? Or is it better to just boil a bit longer after my hops have been added?
Sorry for the long thread. A huge thanks in advance.
