The MAYU Swirl is primarily designed to be used with cold to lukewarm drinking water. But sommeliers and wine lovers are fast discovering that the Mayu works extremely well with wine. It has even been called a wine time machine. The Mayu is one of the fastest wine aerators in the market (6000 times faster than a normal decanter). Taste is a personal issue but in general people find that the Mayu Swirl improves the taste of wine. Although the Mayu works very well with wine two things have to be kept in mind: 1. Taste is a personal thing so what works best for you with which wines is for you to experiment. But that may make drinking wine even more fun! 2. Cleaning the carafe well afterward is important in order for the impeller at the bottom of the carafe to continue efficiently. With red wine the white color of the impeller can turn red over time. Some people chose to have one Mayu caraf for wine and one for water. Note: The Mayu effect on wine has only been recently discovered and we would love to hear your feedback.
