Default Mash pH

For those of you that brew with a pH meter...

What pH reading do you get for an all base malt recipe?

What (if anything) do you do to treat your water?

I carbon filter tap water and add 1/4 tsp lactic acid per 5 gallons and consistently hit a pH of 5.3.

Is the 1/4tsp per 5gal a batch volume or for total strike/sparge volume?

Like Schooly, except I use 1.2 mL of 85% Phosphoric Acid in the mashwater.

Donít try this at home, kids, unless you are comfortable handling strong acids. Itís way cheaper, though. A liter of acid is like $20.

If you donít use acid or acidified grain, youíll come in about pH 5.7.

If you do use acid, the flavors are more distinct, I think

I treat both my mash water and my sparge water at 1/4 tsp per 5 gal of water.
