Popular name for the period between the blossoming of the vine and the grape harvest; this is about three and a half months. In Central European latitudes this corresponds to the period from mid-May/early June to the end of August/mid-September. However, these 100 days should only be taken as a rule of thumb, as the actual duration depends on environmental conditions such as climate and weather, as well as the grape variety, and can be up to two weeks shorter/longer. See also the keywords ripening time, vegetation cycle and vineyard care.
