I've done a few all grain batches the traditional way with a mash tun but I'd like to try BIAB. With the thinner mash, is mash pH something I need to take into account? Do you usually add acid malt or just make acid additions during the mash? Or, since I'm aiming for about 6.5 gallons to boil, is that not something I'll have to worry about? I tried doing some searching and some mention taking it into consideration but others make no mention of mash pH.
