In your January number of Gardener's Monthly, I noticed an article of inquiry about the size and quality of the Gros Colmar Grape. I would not differ very materially from the answer it received from the editor. But as I have had some experience in the cultivation of forcing grapes under glass for nearly twenty years I will give my experience with that variety, and must say that it is a very shy bearer in a cold grapery and not first quality. It produces very large berries but no long clusters, and it takes almost a lifetime before you get any fruit, at least seven to eight years after setting before you get fruit.
