Yummy New Raisins From Our Vineyard to Your Table

grapes before harvest.
Some of your favorite treats for those long, leisurely
breakfasts and festive dinners of the year-end holidays might be made
with plump, juicy raisins. Sweet and chewy, raisins add flavor and texture
to traditional favorites like iced cinnamon rolls, raisin-and-lemon
filled vanilla cookies, crisp apple-raisin turnovers, warmed bread pudding,
or buttered rum raisin sauce spooned over vanilla ice cream.
Raisins also make a perfect accent for creative cuisine
such as a chilled salad of chicken, carrots, and pine nuts; a raisin-mustard-nut
relish to accompany roast pork or other meats; or cheese, raisin, and
pecan-filled chile rellenos.
In the United States, most of the raisins bought for making these dishes, or for simply eating as a convenient and healthful snack, are grown in central California's San Joaquin Valley. In fact, these vineyards yield more than half of the world's raisins. Now, scientists at the ARS San Joaquin Valley Agricultural Sciences Center have developed two new kinds of appetizing raisins for growing in this region.

the new Selma Pete and Diamond Muscat raisin grapes.
Vines of Selma Pete produce impressive quantities of seedless
grapes, which are then dried to form good-sized raisins. What's more,
Selma Pete raisins can dry on the vine after the canes that bear the
grapes are cut. This feature makes them ideal for mechanical harvesting
and thus cuts costs. Ramming named Selma Pete after longtime collaborator
L. Peter Christensen, who is now retired from the University of California's
Cooperative Extension Service.
Selma Pete raisins ripen early and thus are ready to harvest
sooner than many other kinds of grapes. Earliness is a boon for growers,
Ramming points out, because "it reduces the chance that the crop
could be damaged by unseasonably early rains in the fall."
Earliness is also a prized trait of Diamond Muscat, so
named because "it's a jewel of a grape," he notes. With its
rich, fruity, muscat-flavor, this grape provides an important alternative
to Muscat of Alexandria, the muscat most commonly used to make dessert
wines or confections such as chocolate-covered raisins. Diamond Muscat
is seedless. That's a key advantage over Muscat of Alexandria, which
has to be mechanically deseededresulting in sticky, damaged raisins.
Ramming and Tarailo recently made Diamond Muscat and Selma
Pete available to growers and nurseries. This came after a decade of
research during which they inspected more than 400 experimental vines
of each variety and sampled some of the 24,000 pounds of fresh raisins
from these vines. Both raisin grapes are descendants of parent vines
developed in the early 1900s by USDA scientists in California.
Besides being fun to eat, raisins are good for you: they
are fat free and cholesterol free, and provide fiber, potassium, and
