Purification - Patented Selective Sulfite filtration technology removes harmful sulfites the moment their job as a preservative is over, right when you open the bottle. This remarkable polymer removes sulfites and reduces histamines associated with headaches and hangovers without disrupting your wine’s chemistry. Experience improved taste and a smoother finish as natural flavors and aromas shine the way nature intended. Aeration - All new, fully adjustable aeration dials in the amount of air to your liking.
