James Kornacki created the Üllo wine purifier for folks like his aunt who experience reactions to the sulfites found in most bottles of wine. Sulfites are used as a preservative to keep wine tasting fresh as it travels from the vineyard to you. Once you open a bottle, the sulfites' job is done. But some people can get a stuffy nose, redness, or headache from them and others feel they impact a wine’s flavor. So James made a sulfite filter that makes wine taste exactly as it was meant to and that eliminates any potential (and unwanted) side effects. He leaned on his background in chemistry to develop Selective Sulfite Capture™ technology. It’s a food-grade porous polymer that attracts sulfites like a magnet as you pour wine through the filter. You’re left with a preservative-free glass of wine that tastes smoother and won’t cause sulfite-related reactions. The filter can also act as an aerator if you’re sipping on red wine.
