Suitable acid for adjusting PH

[MCHB]

Hi everyone
Usually I adjust PH for mashing grain by Lactic Acid, but I have Tartaric acid available now. Is it also suitable for adjusting PH for mashing or I should buy Lactic acid?

The best acid for pH reduction is phosphoric. Lactic is also great. I would not use tartaric, that is meant only for flavor adjustment in grape wine (it is grape acid).

Definitely no to tartaric acid, it could add a tart flavor to the beer. Lactic or phosphoric acid only.

I believe phosphoric is the best option for acid adjustments. Lactic would be second. I bought 1-gallon of food grade 85% phosphoric acid for $40, which will basically last me forever.
