Lactic Acid

Just wanted to post this as a heads up for anyone who may be trying to use lactic acid to lower their mash pH. There's little info about the actual quantity to use; you want to use a LITTLE. I mean grab your eye dropper little. This stuff is crazy effective, and just a few drops will lower your pH considerably. John Palmer has stated that 2ml/gallon is the upper threshold before it becomes noticeable, which comes to about 1/3 oz. per 5 gallons.

 

Yup, it doesn't take much. Why a good digital pH meter is good tool to have.

 

Bru'n water usually instructs me to add about 1.5 ml to mash and sparge... Depending on the grain bill.

 

Can you recommend one?
