A couple of weeks ago I finally got around to stabalizing and back-sweetening a few batches that were ready. Peach, apple, apple-cherry and a strawberry. Up to this point I just followed recipes for acid additions up front and didn't bother with post-ferment adjustments. Well, I finally picked up an acid test kit and made acid adjustment part of the process. Holy Wine Gawd - what a difference even a small adjustment makes!! Weak flavors pop right out with as little as .5g/L worth of adjustment! If you're going blind on acid, do yourself a favor - spend less than $10 on an acid test kit. It is worth it!!!!! NOTE: Make sure you adjust the acid BEFORE you do any sweetening. Sweetness pops out along with the flavor.
