Blending wine can be as simple as taking two separate wines and mixing them together to complicating things a bit by taking multiple
varietals from multiple regions and blending them to make a new wine with a unique flavor experience. It likely goes without saying, that it takes a lot of experience and a very refined palate to successfully blend wines for today's worldwide market. A winemaker may blend wines for a variety of reasons: to adjust pH,
acidity, alcohol levels,
tannin content or to improve color,
aroma or flavor.
