decay. Metal end posts are approximately 9 feet long and usually
4 inches in diameter.
The posts used between the end posts (in-line posts) are
typically 9 feet in length and approximately 4 to 5 inches in
diameter if wooden and 3½ inches in diameter if metal. The
wooden posts may be pressure treated with chemicals to retard
decay. The purpose of the in-line posts is to support the wires
used to train the vines and support the drip irrigation lines.
The posts support 10- to 14-gauge wires, which in turn support
drip irrigation lines, vine cordons and fruit, and foliage. All
wires are attached, by staples and gripples, to the end posts and
the in-line posts. The staples attach the wire to the posts, and
the gripples provide the ability to adjust the tension of the
In addition to in-line posts, wood or metal training stakes
are pounded 1½ to 2 feet into the ground to support each vine.
The stakes may be wood or metal and are typically 6 feet long,
and the wooden ones may be pressure treated.
Concrete or cement is not used to affix the posts to the
earth. Petitioners did not intend for their trellising to be
permanently affixed to the earth.
One goal in the use of trellis systems is to improve the
intensity and quality of grapes, which, in turn, improves the
intensity, quality, and value of the resulting wine. The manner
