The results of this New Zealand based study found that the tasting impact of the BioD calendar was, essentially, nada. The results of a much more scientific and potentially relevant experiment into whether or not the BioD calendar impacts how a finished wine tastes were recently published. My tasting results? In summary: totally random, with no correlation to the BioD calendar days at all. Presumably, I would have enjoyed more of the wines on so-called “fruit” days, and wines would have tasted nastier on “root” days thus postulated the Biodynamic calendar, anyway. I then tasted through wine samples pretty much every day, as usual, and noted whether or not any given wine seemed to taste really good or really nasty, and what BioD calendar day type it happened to be. This study had a single participant (me) who knew next to nothing about this calendar, who downloaded one of those mobile apps that tells you what type of day it is on the BioD calendar.
A couple of years ago, I undertook a rather statistically-irrelevant and thoroughly un-scientific study regarding the Biodynamic tasting calendar (based on the lunar-cycle farming techniques espoused by Rudolf Steiner).
