Üllo is a revolutionary new wine purification product that removes sulfites, restoring wine to its natural, preservative-free state. Üllo believes that wine is best enjoyed the way the winemaker intended pure without the added sulfites used as a preservative. An estimated three million Americans are sensitive to sulfites resulting in allergies or respiratory problems, while countless others blame these chemicals for headaches and hangovers. Üllo purifies any wine, restoring it to its natural state. Üllo purifies wine using a porous, food-grade polymer filter to selectively remove sulfites, while allowing the other compounds in the wine to flow through unaffected. Through Selective Sulfite Capture™, Üllo maintains the original flavor and character of the wine while reducing sulfites to a more naturally occurring level of less than 10 ppm.
