It just may be that lunatics and the tide aren't the only things affected by the moon, but your wine as well. According to the biodynamic lunar calendar, the taste of wine will differ depending on the cycle of the moon. A lunar calendar has been used for centuries by gardens as a way to schedule the optimal time to plant and harvest certain herbs, flowers, vegetables, and fruits.
There are 4 types of days in a biodynamic calendar: Root, Fruit, Vegetable, and Flower.
Fruit and Flower days are said to be the best days to drink wine, enhancing the fruit and flower flavor profiles of the wine, creating a more aromatic and vibrant taste. However, Root and Vegetable (or Leaf) days, will have the opposite effect, leaving the wine more closed off, tannic, and earthy.
A great German grandmother, Maria Thun, has been creating a calendar for the past 50 years highlighting the "Good" and "Bad" days to drink wine, and some of the biggest players in the wine supermarkets have taken it seriously.
Tesco and Marks & Spencer, two supermarkets based out of England, support her philosophy, and only invite critics to taste wines on days in which the calendar indicates the wine will taste favorable.
Thun's 2015 Calendar is available on Amazon.
According to a calendar we found on google the best wine days for January / February are the following:
January 17, 18, 24, 25 FRUIT ***Best Days to Drink Wine
January 11, 12, 20, 21, 28, 29, 30 FLOWER **Good Days to Drink Wine
February 2, 3, 4, 12, 13, 20, 21 FRUIT ***Best Days to Drink Wine
February 7, 8, 16, 17, 24, 25, 26 FLOWER **Good Days to Drink Wine
(Sounds like a taste test is in the future)
