The Wave removes BOTH the histamines and sulfites that cause allergic reactions from wine. It is portable, convenient and purifies an entire bottle of wine as you pour. More than 95% of the tannins, phenolics and antioxidants are maintained in the wines so “all the natural good things” are still there. All testing was done by a leading independent wine testing lab. The Wave works on all red and white wines. It is a convenient, single-use product that requires no messy cleanup. Once removed from the packaging, the air tube that is attached to The Wave should be inserted no more than ½ inch into the stem segment. The Wave is ready to use and should then be inserted snugly into the mouth of the wine bottle. Wine is purified as it is poured into your glass. The flow rate of wine through The Wave is controlled by how steeply the bottle is positioned. The steeper the bottle, the faster the wine will pour. Keep in mind, the slower the wine flows through the filter, the more histamines and sulfites will be removed. After the first glass is poured, there may be a small delay of a few seconds before wine comes through the filter housing, but don’t worry, that means The Wave is working! Histamines and sulfites are often the source of bitterness and noxious odors in some wines. The Wave purifies the wine so the natural flavors and aromas of wine will be noticeably enhanced, thus making the wine taste “smoother” and “less bitter”. Taste testing studies were performed by a leading Sommelier education program. Not only are your wine headaches eliminated, but the wine can be even more enjoyable! Wine purification really brings out the best in wine!
