You can never have too many wine festivals so don’t let September go by without going to at least one of them.  Especially as this is in honor of Saint Wenceslas.  It is said that the saintly Wenceslaus himself planted and harvested the grapes from which the lovely wines at the Prague Castle are produced.  Have some wine and good food while enjoying the music and beautiful views.  At Villa Richter in Hradčany.
