WHAT EXACTLY IS THE SPRING MOUNTAIN DISTRICT APPELLATION?

We thought you might be interested in the technical details of our appellation, which was granted in 1993. Our friends and neighbors who organized the proposal are Michael Marston, Fritz Maytag, Robert Craig, Richard Mendelson, Charles Heintz and Marshall Newman.

Sec. 9.143 Spring Mountain District.
(a) Name. The name of the viticultural area described in this section is
``Spring Mountain District.''
(b) Approved maps. The appropriate maps for determining the boundary of the
Spring Mountain District viticultural area are four U.S.G.S. 7.5 minute
series topographical maps of the 1:24000 scale. They are titled: (1)
``Kenwood, Calif.,'' 1954 (photorevised 1980). (2) ``Rutherford, Calif.,''
1951 (photorevised 1968). (3) ``St. Helena, Calif.,'' 1960 (photorevised
1980). (4) ``Calistoga, Calif.,'' 1958 (photorevised 1980).
(c) Boundary. The Spring Mountain District viticultural area is located in
Napa County, California, within the Napa Valley viticultural area. The
boundary is as follows:
(1) Beginning on the Calistoga quadrangle map at the Napa-Sonoma county line
at the boundary line between sections 18 and 19 in T8N/R6W.
(2) Then east along the boundary line between sections 18 and 19 for
approximately 3/4 of a mile to its intersection with Ritchie Creek at the
boundary line between sections 17 and 20.
(3) Then northeast along Ritchie Creek approximately 2 miles, to the 400
foot contour line in the northeast corner in section 16 of T8N/R6W.
(4) Then along the 400 foot contour line in a northeast then generally
southeast direction, through the St. Helena and Rutherford quadrangle maps,
approximately 9 miles, past the town of St. Helena to the point where it
intersects Sulphur Creek in Sulphur Canyon, in the northwest corner of
section 2 in T7N/R6W.
(5) Then west along Sulfur Creek (onto the Kenwood quadrangle map) and south
to the point where it first divides into two intermittent streams in section
3 in T7N/R6W.
(6) Then south along the intermittent stream approximately 1.5 miles to the
point where it intersects the 2,360 foot contour line in section 10 in
T7N/R6W.
(7) Then southwest in a straight line, approximately .10 mile, to the
unnamed peak (elevation 2600 feet) at the boundary line between Napa and
Sonoma Counties.
(8) Then in a generally northwest direction along the Napa-Sonoma county
line, through sections 10, 9, 4, 5, 32, 33, 32, 29, 20, and 19, to the
beginning point on the Calistoga quadrangle map at the boundary between
sections 18 and 19 in T8N/R6W.
