does lactic acid drop PH any better than gypsum? Is that something good to have on hand to acidify sparge water if the need arises?For adjusting mash pH, I'll just add it to the mash. My water pH isn't very high, so I'm not terribly worried about the sparge water raising the pH of the mash too much during sparging. If I was concerned I'd acidify my sparge water with some lactic acid. If I'm just looking for sulfates or chloride for flavor balance, I'd add it to the boil kettle.

Lactic acid will drop the pH of anything whereas gypsum will only drop the pH of the mash. In other words, you can't use it to lower the pH of your sparge water. Lactic and phosphoric acids are very good for that. Note that you don't really need to do that if you batch sparge but it's a good idea if you fly sparge.does lactic acid drop PH any better than gypsum?

And by adding gypsum, you're adding sulfates to the mash, which may or may not be appropriate.Lactic acid will drop the pH of anything whereas gypsum will only drop the pH of the mash.

True but the same thing applies to calcium chloride: it doesn't lower water pH. Salts don't lower pH per se but calcium causes reactions in the mash that produce acids that do lower pH. Carbonate is a buffer that resists the lowering of pH and so counteracts the effects of calcium.And by adding gypsum, you're adding sulfates to the mash, which may or may not be appropriate.
