Notes

2024-03-16 Last batch was nice. Got some feedback from stormcrow. We missed the carbonation on it massively when canning so that will be better next time. Also, it was "a lot roastier" than when they make it so changing some of the process. Adding the milled dark malts super late in the mash and putting in less. I needed to change the 0.5 lbs of Carafa I to Carafa II so that goes down to 0.25 and I'm using 1 oz less black prinz (4 to 3).
Been a year, making this again after having lived on czech dark lager. Editing the original recipe a little bit to include the fact that the dark malts are only added in the mash right before the bag is pulled. Getting the color out and only a small amount of roast. This was originally done, but wasn't reflected in the recipe. Also adjusted the acid slightly up to keep the mash pH below 5.4 as the dark malts would not participate in the enzymatic rest and not contribute the pH there.

Original malts were Sugarfoot Sue (Vienna) and Whisper Sister (Pilsner) from Gateway Malting, https://gatewaymalt.com/
Thanks to StormCrow Brewing for the recipe.
Gonna give OYL-044 a try. Supposed to be like WLP-029... we'll see.
Didn't have black malt, got black prinz, same Lovibond
didn't see Dark Chocolate, got briess chocolate.
