Baga

Baga is a red wine grape both originally and now largely grown only in Portugal's Bairrrada DOC.  One of the few grapes on planet Earth able to produce highly tannic wines, with high acidity in almost any growing environment.  Baga is one grape which is wel suited to be cellared for some time, although it is rarely if ever, given the type of high quality growing conditions required for decades of time in a cellar.
