When you say the pH of the wort and not the sparge, are you saying that it doesn’t matter my sparge water is 8.3 as long as there is enough acids in the grain to get the combined sparge water and grain to lower than a pH of 6?
Are acids in the grain diluted/run off when you do your first run off?[/quote]
Yes, as long as there are sufficient buffers in the grain to maintain the proper pH your fine.
As you sparge the pH will change.
There’s a lot of things at play here and all will effect your pH. Water chemistry, grain bill, sparging.That’s why you need to take pH readings a various points during the process and make adjustments accordingly. It also helps to use an accurate water chemistry spread sheet such as Brunwater to put you into the right ballpark from the start.
It’s overwhelming at first but you’ll find the more you work with your water the easier it gets. Pretty soon it will just become second nature.
