All Grain Brewing / Adjusting RA with Lactic - How much is too much?
« on: December 31, 2009, 09:58:17 AM »
I have very hard water (great for SRM of 26+) and have been diluting my water with as much as 75% RO for a light colored beer to get RA in line with Palmer's spreadsheet (and then adding back the minerals needed to get balanced again). This means as much as 4+ gallons for a 5.5 gallon batch. At $1 a gallon, that adds $4 to each batch. 
Although hard, my water has well balanced minerals. So..... I am wanting to make the adjustments with Lactic acid instead of RO and salts. Apparently I need to add 3 ml of 88%-lactic acid to get the RA where it needs to be to get the proper pH.
Is there a limit as to how much lactic can be added before flavor starts to suffer?
Thanks!

, I was wondering just how long they would be good for. Will they just gradually go downhill and lose its banana and clove features or will they just go bad (such as taste bad)?
Are we talking 3 months? 6 months? or a year? They will be kept refrigerated all the time.
