In previous posts we covered key dates related to alcoholic drinks; here are the ones from August to December
“Unfortunately, these glasses are not the right ones; styles change. For a dry martini, the ideal glass is cone-shaped” is a line from the film "The Discreet Charm of the Bourgeoisie", which tells the story of a group of bourgeois friends who plan to have dinner together and experience a series of very unusual events between one course and the next. As in that scene, you may not always have the perfect glassware to hand, but there will always be one of those key dates that gives you a reason to enjoy a get-together with friends from the past and present. 
For a gathering with friends, there is always a key date worth celebrating. In previous posts you can read the calendar dates for the months from January to July:
