Readers looking for a super bargain should check out Montelena's 1993 Johannisberg Riesling from Potter Valley. This dry, Alsatian-styled Riesling is an exuberant, medium to full-bodied wine with gobs of peach/apricot fruit, long, well-extracted flavors, and a crisp, dry finish. Drink it over the next several years.Tel. (707) 942-5105; Fax (707) 942-4221.
