Ph Testing

[kevin_smevin]

You can also adjust pH of your brew by using acidulated malt. Each 1% of acidulated malt you use (as a percentage of the entire grain bill) is said to reduce mash pH by 0.1. I've not tested this but its what the weyerman specs say. Keeping your pH low will result in a paler beer - higher pH tentds to strop more colour from your grains

Or you could add lactic acid - since that is essentially what the acidulated malt does - but doing both/either without testing seems to be a very inexact method.
