There's Numbers in the Vineyard

Sometimes numbers are comforting. They get kicked around lot but I've been able to settle on a few for the typical vineyard.

Iowa State University Extension has good information about vineyards.

545 vines will cover an acre very nicely. There can of course be more or less depending on spacing of vines and row width. It costs about $10,000 and 3+ years to get one acre of vines to produce a good crop.

Then there's about 4000 bottles of wine in an acre of grapes.

This site shows 400 vines per acre and the Benzinger site show 1089 vines per acre. I'm comfortable with 545.
