Dear Dr. Vinny,
I've noticed that many older bottles of Vintage Port have what appear to be streaks of white paint on them. Where do these come from?
—John K., San Juan Capistrano, Calif.
This white mark is also called a splash mark, and it tells you which way the bottles were cellared (splash mark up). This way, all the sediment collects on the same side. Smart, huh?
