Matching trellis to terroir

摘要

In Washington, most wine grapes are trained in a vertical shoot positioning system. Dubbed VSP, the trellis and training method is clean, allows a lot of airflow, provides abundant sunshine and is easy to mechanize. But it's not the only choice. "That's the one I put in because that's the one everybody sees, and it's probably the most common one," said Don Phelps, owner and grower at Hard Row to Hoe Vineyards in Manson, Washington. "But after a while I started to question and (travel) and started tolook at other systems, too."
