The best wine I think I ever made was an accident! I was making a triple batch of Brunello and a double batch of Barolo. Both were somewhat disappointing in the final stages. The Brunello was too thick, just thinner than a light syrup and the Barolo was very thin and lacked the classic "brick red" color of the wine. I thought perhaps a blend of the two might be in order, so I made up three sample ratios of Brunello:Barolo of 60:40, 75:25 and 80:20 and had our friends in our "Gourmet Club"* taste the three and choose their favorite. They unanimously selected the 75:25, which I liked the best also, so I blended the wines and called it my "Gourmet Select." If I may say so myself, it was the best tasting wine I ever made, and I would stack it against store bought wines in the $40-60 range. It is gone now and only a wonderful memory amongst our group.
* I hasten to point out that the members were "gourmets" in name only. We were just four couples of old friends who like to eat and drink wine. We would have meals quarterly at a host's home on a rotating basis where the host was responsible for the main course and the others would fill in with courses like appetizers, salad, vegetable, starch and dessert.
