This goes in all my light colored brews. I use spring water (may as well be RO or distilled - it has almost nothing in it). In those conditions 2% of this malt has hit my mash pH range every time for IPAs and blondes. I have lactic and phosphoric acid on hand for emergencies, but have never needed to adjust the mash pH with those. TIP 1: Buy a few pounds and reseal with a vacuum resealer (you only need 3-5oz per 5gal batch typ). TIP 2: crack the grains or don't crack the grains - it doesn't matter. Just get 'em in the mash tun. The lactic acid is on the outside.
