Never brewed the style, don’t really brew a lot of IPA’s as it is but anyway I have .25 lb (~3%) each Midnight Wheat and Black Prinz malt for a small batch (3 Gal at end of boil) Black IPA. I’m a bit torn between just adding dark malts in the mash the whole time or adding them near the end of the mash. I recirculate the entire time and I plan on a bit higher mash ph as I do with all my dark beers. I brew a lot of Porters and Stouts, but obviously this is meant to be a smooth, subtle roast character but the only thing I worry about adding them near the end of the mash is not getting enough color? I want it more than dark Brown. It is going to be a bigger ~8% version so I guess you want SOME roast character there and not strictly just color…but it’s a fine line I guess. I do have them crushed and packaged separately, maybe I can add the Midnight Wheat for the whole mash and the Black Prinz near the end of the mash.
When I make my Black IPA, I just put the dark malts right in with the rest of the grist. Of course I use RO water and adjust my water profile for the style and the pH falls right in line with what I am looking for. The beer always comes out great and I have medalled many times with this beer.
If you want to put the dark grains in after the conversion is complete, I would recirculate at least 10 minutes or so before collecting the wort. I do that during the mashout with my big stouts since the dark grains drive the mash pH way down and compensating with acid is tough with such a large grain bill. You should be able to get the color you want with this method. So, it boils down to (no pun intended) your personal choice on how you want to do this. Either way will work.
When you guys do what you do, are you calculating the mash pH desired using the ultimate final grist components or the initial (paler) grist? It would seem to risk too low of a final mash pH, if the pale grist is treated for its desired acidification and then adding dark grains at vorlauf. Any problems there?
I look at the predicted pH with all of the grains in Bru’n Water and also with the dark grains left out. That way I can decide whether to leave them in or put them in during mashout. Like I said, when I make my stouts, the dark grains pull the pH too low so I leave them out until mashout. With the Black IPA I don’t see the pH pulled beyond the ideal range by mashing the dark grains with the lighter ones and I measure the mash pH every time just to make sure.
I can’t argue with Brewbama’s method. If it works for him, great! I have done it both ways and have had success with either method.
I’ve been adding dark malts at mashout for close to a decade. Even in stout. For me, it’s just easier and I don’t have to worry about changing ph. Smooth as silk and no harshness, just roasty flavour goodness
I would wonder if that has a negative impact on the flavor the dark grains impart by doing this in the kettle especially when the wort gets diluted by the sparge. If it is done while collecting the wort, it could work. Just curious.
Good point. I was just curious on this especially iif you re heating the wort to boiling while collecting. If that isn’t being done, then I agree, there probably wouldn’t be much difference, if any.
