The Fruit and Wine Reporter says, there is a great difference in varieties for winter keeping. The very early sorts are, in general, poor keepers. Hartford and Adirondacs are examples of the earliest, and both are transient. The Delaware may be kept for a while with considerable ease, but it soon loses character. The Concord is, perhaps, the shortest lived of all. Its thin and tender skin will hardly suffice to carry it to market in presentable condition, and frequently cracks on the vines. A tough skin and bunches not too compact, are excellent qualifications. The Isabella is supposed to be a good keeper, but it too often loses its flavor after a few weeks, particularly if allowed to become dead ripe, as it did last fall. Wherever the Catawba perfects itself, it is a safe variety for winter keeping. The Iona is one of the best also. It retains it spiritus vinus flavor for a long time. The Israella is said to keep well by those who have tested it.
Some of Rogers Hybrids promise to be exceedingly valuable in this respect. No, 1 keeps well and seems to improve in quality. Some of the black varieties such as 4, 19 and 43, have succeeded well with me. Among the reds, No. 15 and Salem seem to equal or surpass all others. Salem is much the best quality; and to the majority who eat it, not surpassed by any other variety. Fruit of this, gathered in September, is still in perfect condition, and promises to continue throughout the winter.
