Glen Manor Vineyards is located in Virginia approximately 70 miles west of Washington D.C., situated on a western flank of the Blue Ridge Mountains. The surrounding mountains, ranging between 1400 and 3400 feet in elevation, form a “Glen” which gives the vineyards a unique environment: A world of its own. The vines grow high on very steep mountain slopes characterized by deep, well-draining, and rocky soils.
The original six acre vineyard was established in 1995. Here, we grow Sauvignon Blanc and four red Bordeaux varieties: Cabernet Sauvignon, Merlot, Cabernet Franc and Petit Verdot. Resting between 1000 and 1200 feet in elevation with the valley floor below at 800 feet, this mainly western exposed vineyard site’s soils are deep and well drained, with low to moderate water-holding capacity. These soils are comprised of Myersville-Catoctin Complex, Chester Manor, and Chester loam, with formed-in weathered products of green schist, granodiorite and greenstone.
Vine density of the original vineyard is 454 and 908 vines per acre. These vines were originally cordon trained and spur pruned, but all have been converted to cane pruned and all are growing on the Open Lyre trellising system. A permanent covercrop grows between the rows and under the vines to wick away water, thus controlling the vines summertime growth. The red Bordeaux varieties are cropped at 1.5 to 2.5 tons per acre; the Sauvignon Blanc is approximately 4 tons per acre.
In 2006, establishment of a new vineyard site began with the clearing of a young forest on higher ground just northeast of the original vineyard. A long and deep ravine runs between the two vineyards, carrying both water and cold air away from the vines. This new site, ranging between 1100 and 1300 feet in elevation, has very steep slopes of deep and very rocky soils. These slopes face in all directions with the largest slopes facing west and south. At the top of the site is a plateau of about 3 acres. The vineyard soils are Tankerville-Purcellville Complex, Philomont-Tankerville Complex and Myersville-Catoctin Complex. The entire site of 25 acres was planted with a blend of dense, low and slow growing grasses that require very little summer maintenance.
An initial 4 acres of vineyards were established in 2008, with Petit Manseng and Merlot planted on the plateau, and Cabernet Sauvignon and Cabernet Franc on the southern slopes. Vine density is 1361 vines per acre and all are cane pruned and trained to the Double Guyot system. In 2009, an additional 4.5 acres was planted of Cabernet Sauvignon and Merlot on a west slope and Cabernet Franc on a south slope.
