During the testing of the product our Oenologist (wine specialist) made some tasting comments “It’s like you have taken an old flabby wine and made it young again… the taste is brighter, fresher… the tannins have become smoother… the fruit notes have become more dominant.”Everyone has their own taste preferences.  We believe that in the case of low cost wine and sulfite-heavy wines, UBfree actually improves the taste by bringing out the more fruity and woody aspects of a young vintage.
