PREVENTING WINE ALLERGIES
Biogenic amines, more generally called “histamines” are chemicals made by our digestive and immune systems. They are also naturally found in many foods and fermented beverages. The histamines in our bodies provide important benefits such as fighting infections and regulating sleep. The histamines found in foods and beverages are surprisingly common. They are especially prevalent in food/drink that is aged or fermented, such as cured meats, aged cheeses or fermented beer, ale and wine. These consumable histamines can trigger allergy-like responses that are unmistakable to the sufferer. As is true with most food intolerances, some people are more sensitive to histamines than others and need to incorporate low histamine diets into their lifestyle.
In the case of wine, histamine precursors are found in the proteins that are in the skin of grapes. The histamines are formed when the juices produced from the grapes are fermented. As a rule of thumb, the thicker the skin and the darker the wine grape – including varietals such as cabernet sauvignon, merlot, syrah, sangiovese or tempranillo – the higher the levels of histamines in the wine the more likely people with histamine intolerance will experience allergy-like side effects. For further details about histamine intolerance, see our Blog.
The Wand™ and The Wave® are the first and only products available that filter and remove the four kinds of biogenic amines found in wine that cause allergic reactions. We hold a range of patents based on selectively filtering these histamines and sulfites from wine without altering any of the remaining components of wine (tannins, antioxidants, etc.) that give wine its characteristic taste, aroma and color.
Sulfites are preservatives that are formed naturally during grape fermentation and are also universally added to wine. Sulfites will prevent spoilage and oxidation in the bottle thus extending shelf-life and enhancing the beneficial aging processes of wine. Sulfite allergies (sensitivities) are less prevalent than histamine allergies, but yield many of the same symptoms. For further details about sulfite sensitivities, see our Blog.
The U.S. and the E.U. both require wine labels to state “this wine contains sulfites.” Most wines contain between 10 – 200 Parts Per Million (PPM) of sulfites. You may see wines that call themselves “organic” or say “low sulfites,” but all wines do, in fact, contain sulfites; no wine could go from bottle to table without them.
Men and women, young and old, can all suffer from wine allergies (intolerance). You’re not alone! For women, side effects from wine allergies often appear for the first time, or increase in severity, during and after menopause due to changing hormones that affect the immune system. For men also, allergy-like symptoms of wine intolerance often become more acute during middle-age.
A genetic predisposition towards wine allergies can also exist for some people. If your ancestors came from a part of the world such as Northern Europe or East/South Asia that did not consume products made from fermented grapes, it’s possible that they did not build up the same immunities that people from historical wine consuming regions like the Mediterranean did. Your heritage is not an automatic determinant of whether or not you have a wine allergy, but it is a contributing factor.
Wine allergies also reflect our own individual diets, what we eat and drink from a young age and how those habits affect our individual “microbiome,” and its effect on our immune system. A low histamine diet that avoids processed foods and the kinds of histamine-rich foods such as cured/aged meats and cheeses does reduce the likelihood of wine allergies.
Finally, wine allergies can also be triggered by interactions with certain kinds of drugs, especially sulfa or sulfonamide drugs, including anti-diabetic agents and diuretics. Please consult your physician if you are taking any kind of prescription drug and wish to understand about possible side effects. For additional information about the factors contributing to wine intolerance, see our Blog.
Wine is filtered several times during the winemaking process, before it goes in the bottle. Wine filtration is used to remove grape skins, pulp and stems so it is “clear,” i.e., there are no visible particles, and also to remove certain compounds, e.g., excess tannins.
Many people use wine filters at home to remove any remaining particles that are still in the bottle. These filters work simply to trap particles so they do not emerge when pouring wine into a glass or decanter. Part of the function of The Wave®, our solution for purifying an entire bottle, is to remove particles that you can see.
Yet The Wave® and The Wand™ both do so much more. They remove the undesirable components that you can’t see – the histamines and sulfites. These are present in all types of wine and are the main triggers for wine allergies.
In blind taste tests, even wine experts express a preference for wine purified by PureWine™ products, because they allow the natural characteristics of wine to be experienced more intensely. Wine purification really brings out the best in wine!
Wine has a complicated relationship with oxygen. When wine is exposed to oxygen in the air, it evolves over a long time period, as the tannins (which make wine dry and astringent, but wonderfully complex) soften and the aroma and color flourish. Yet wine ages quickly when exposed to oxygen, and can then turn bad. We have all experienced the bottle of wine that quickly oxidizes and becomes bitter and undrinkable when left exposed to oxygen for a couple of days.
Both The Wand™ The Wave® aerate wine by managing the complex effects of oxygen, to bring out the intensity and structure of wine. The Wave® aerates wine as it is poured from the bottle while The Wand™, our by-the-glass solution quickly aerates wine during the stirring process.
The patented Phoenix® technology is present in all PureWine™ products. It selectively removes the oxidized components in wine that cause the bitter, undesired taste when wine has been exposed to oxygen for too long. With the Phoenix® technology, many wines that have become bitter due to oxidation can be “resuscitated”. So you no longer have to dispose of wine that has developed that “old wine” bitter taste. No more wasted wine! And along the way, the histamines and sulfites are also removed so you once again have nothing but Pure Wine.
USING PUREWINE PRODUCTS
The Wand™ is our portable, convenient, by-the-glass wine purification product. Once it is removed from the packaging, it is simply placed into a 6 oz glass of wine for at least 3 minutes. With intermittent gentle stirring, it will remove over 50% of the histamines and sulfites from the wine. After 8 minutes, as much as 95% of the histamines and sulfites can be removed. Don’t worry, you can leave The Wand™ in your glass as long as you would like. The longer you keep it in, the more it will purify your wine. The stirring action helps to aerate and purify the wine at the same time. The Wand™ is single-use and can be disposed of in the household garbage.
The Wand™ comes with four different wine charms that can be easily twisted off the handle and attached to the rim or stem of your glass. This is an added bonus that let’s you personalize your glass and differentiate your glass from all other glasses at the party. You will never lose track of your glass of wine again, hurray! Click here for an instructional video on how to use The Wand™.
The Wave® is our whole-bottle wine purification product. It purifies an entire bottle of wine by removing the histamines and sulfites from your bottle of wine as you pour. It is a convenient, single-use product that requires no messy cleanup. It is made from earth-friendly bio-renewable plastics and can be disposed of in the household garbage.
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, as shown on the enclosed instruction card. The Wave® is ready to use and should then be inserted snugly into the mouth of the wine bottle. Your 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. After the first glass is poured, there may be a small delay of a few seconds before wine comes through the filter housing. Click here for an instructional video on how to use The Wave®.
The PureWine™ filtration technologies have been thoroughly tested by a leading independent laboratory to confirm that the histamines and sulfites are being effectively removed from a wide range of wines produced in the leading wine growing regions throughout the world, see the Infographics above.
The many thousands of testimonials from our happy customers tell our story better than we can ourselves. Read these testimonials and success stories here.
The Wave® and The Wand™ work on all red and white wines. The Wand™ also works with rosé wines and sparkling wine, such as champagne or prosecco, but the stirring action may cause them to lose their effervescence more quickly if used beyond the recommended 3-8 minutes.
The histamines (biogenic amines) and sulfites that are naturally produced in all wines during the fermentation process have very potent bitter tastes and noxious odors. Even at very low levels in wine (parts per million), they can be overwhelming and are capable of masking the desired tastes and aromas of the natural wine.
All of our PureWine™ products remove the histamines and sulfites that cause the symptoms of wine allergies (intolerance) and they have an additional benefit, the bitter tastes and noxious odors are also removed from the wine at the same time. Through this process, the natural flavors and aromas of some wines will be noticeably enhanced, thus making the wine taste “smoother”, “more rounded” and “less bitter”. So not only are your wine headaches eliminated, but the wine may be even more enjoyable!
For bottles of wines that have been left opened for a few days, the Phoenix® technology in all Purewine™ products comes to the rescue. Phoenix® is able to remove the oxidized components in wine that cause the bitter tastes to develop and mask many of the desired wine flavors. When the oxidized components are removed, the “resuscitated” wine will have the natural tastes and odors once again.
The side effects of wine intolerance are not necessarily related to the quality of the wine. Some high quality (expensive) wines have quite low levels of histamines and sulfites, but there are other very expensive wines that have very high levels. Similar variations occur for less expensive wines. More directly, high levels of histamines are related to critical variables such as the type of grape, quality of the grape and the fermentation processes used.
The PureWine™ filtration technologies have been designed to remove histamines and sulfites when they are present in beverages.
Both The Wave® and The Wand™ are single-use products. One Wave® will purifyan entire bottle of wine and one Wand™ will purify a single 6-ounce glass of wine. Complying with this usage will ensure the most effective purification of histamines and sulfites. Effectiveness can be significantly decreased if The Wave® is used for more than one bottle, or if a Wand™ is used for more than one glass of wine.
The Wave® is made of bio-renewable plastic and can be recycled once you have removed the filter that is inside the top housing. Just gently pry the housing apart to remove the filter. The housing, stem and air tube go in the recycling and the filter cartridge goes in the trash.
The handles of The Wand™ are made from food-grade, BPA-free polypropylene plastic and are 100% recyclable; just remove the filter from the handle and place the handle in the recycling. The contents of the filter are not recyclable – they are resin beads that contain the absorbed histamines and sulfites – but you can dispose of the filter safely in the trash.
