As appropriate for wines as it is for water, the decanter sits into its dedicated cooling coaster to keep your choice of beverage suitably chilled. If a full-bodied red is more your thing, the decanter’s conical foot placed on the table cooling coaster allows a gentle rolling rotation to bring out the best in that Cabernet Sauvignon.To mitigate condensation on your table, a fabric place mat is included.For best cooling results, chill the coaster in the freezer, and your preferred beverage in the refrigerator, for an hour prior to use. The chilled coaster should then keep your drink sufficiently cooled for about 2 hours. If a dropped or damaged coaster leaks coolant, the liquid is water and poses little risk.
