This is actually the first year in a long time that I have a batch aging -- using wild grapes growing on my property. The first wine I ever made (from a kit), unbeknownst to me, needed to be aged to taste good. Once I learned that, I did the same test: every few months I'd open a bottle and taste it. After a year, most of the "tarry" flavors were gone, after 3 it was getting good. At five I really liked it. Unfortunately, no bottles survived to the 10-year mark, but I did learn to make wines that matured a lot faster!
