Batch sparge acidification

[motobrewer]

I don't know anything about sparge acidification. Is it different for batch spargers? What should I acidify the sparge to?

I'm using RO water.


Thanks.

Should be no different treatment between batch and fly sparging.

That said - if you are using RO water, you will likely not need to acidify your sparge water - the alkalinity is already very low.

If you're sparging with RO water, you don't need to add acid.

That's what I try to do, whether I fly or batch sparge. (I go back and forth).

I personally use Bru'N water to calculate my sparge acidification and lactic acid to acidify. I generally shoot for something like a 5.3-5.6 pH.

As mentioned, you probably don't need to acidify if using RO water.

If you do decide to acidify, it only takes a teeny tiny drop of 88% lactic acid to drop the pH of a couple gallons of sparge water.

tanks. and planes.

That fact in itself says you don't need to do it.

Good point.

Would that be the same using distilled water, no need to acidify?

Correct. RO and distilled are ultimately about the same thing, they just get there two different ways
