For one weekend in September 1400N-1600N Wells is converted in to a huge winery. All aspects of wine making are demonstrated and you may sample wine from a variety of different vineyards from arount the world. This festival combined with the fact that it is in Old Town, my favorite neigborhood in chicago, make it a must go every year. I have travelled thousands of miles to attend this festival. If you like wine and Chicago this is a won't miss event. Don't bring the kids I have seen it get a bit ugly on ocassion.
