When you buy a bottle of wine to enjoy at home, wouldn’t you like to know when it’s going to be at its best? Based on the unmatched Maria Thun Biodynamic Calendar, this handy little pocket guide tells you which days are optimum wine-drinking days, and which days to avoid if you want to get the most out of your glass. At least two major supermarket chains only do their wine tastings on the best days as indicated by this calendar! Includes a bonus month, December 2019, to cover the Christmas season.
