The Ice Wine is starting up this weekend. Including free cooking demos from Chuck Hughes and Anna Olson this weekend:
General Niagara Ice Wine festival site:
I didn't go last year but went for a few years before that. Overall a fun outing. Both the Niagara on the Lake and the Jordan weekends are fun because you can try a bunch of different things at a "Festival" type atmosphere. But, definitely make it out to some wineries as well.
