Does acidulated malt affect fermentation?

[Miraculix]

I have a customer that insists on making sours by adding acidulated malt in the mash at 20%!!!! I keep trying to tell them that is not the way to make sours but he says he likes the taste.......and complains that his ABV is too low and his fermentation stops.
Oh well....

Maybe it would be better for him to just mash without the acidulated malt first and then later on, when the conversion of the "normal" malt already happened, to add the acidulated malt afterwards for half an hour or so. That way only the starch from the acidulated malt will have ph issues while converting.

Some people just don't WANT to learn...

You got that right....quoting a former teacher, "we can do something about ignorance, but nothing about stupidity."
When they chose not to learn, I move them from Ignorant to STUPID

Now that would just freak them out
