* White Marsh Cellars, 2810 Hoffman Mill Road, Hampstead; 848-4488.
This vineyard, established in1981, is named after a parish church on the Eastern Shore between Easton and Trappe. Dewitt F. Truitt, owner and operator, said he takes special pride in the manner in which his wine is fermented.
Made in small oak barrels, the wine has more body and a more distinctive flavor than those produced in larger barrels, he said.
This year thevineyard expects to produce 4,000 gallons and will market the wine under the name of "Aspen Run." Mr. Truitt's main objective is to produce an older, European-style wine that is "superior for meals."
It now produces dry reserve Chardonnay and Seyval together with other semi-dry whites and blush wines. Tours are by appointment only.
