I'm looking to buy a 20 gallon mash tun (Blichmann boilermaker or SS Brewtech) with false bottom. SF Bay Area. Happy to pick up a used item in decent shape.
Yeah it's certainly possible, though I've double checked everything and even rewrote the recipe. It would appear that BF and Bru'n calculate bicarbonate differently (slaked lime drops the bicarbonate level in BF whereas pickled lime increases it in Bru'n).
Agreed, the 250ppm bicarbonate should do it. I actually went ahead and plugged the info into Bru'n Water and got an estimated PH of 5.56 using the same additions, grain bill, etc. I'm thinking that Brewer's Friend is off on this one. Thanks for the sanity check!
Yeah good point... I've heard that some folks add most of their dark grains in during the last 20 minutes of the mash (they keep something like 10% of the dark grains in with the base malt and add later). This is something I may have to try... curious if this has worked out well for other folks...
Hey ya'll -
I'll be brewing my first Russian Imperial Stout sometime over the next couple of months. In working up my recipe, I noted that my overall PH is incredibly low even with my bicarbonate levels at an appropriate level. Here's where I'm at with my current water profile:
Ca: 90
Mg: 15...
