After much experimentation they chose as their main grape variety Alphonse-Lavallée, a seedless French vine used elsewhere for table grapes. They're grown on overhead trellises, using small trees as supporting posts which also have to be pruned. Besides keeping the workers cool this system reduces the risk of diseases and sunburn on the grapes, all contributing to a better fruit quality. Keeping grapes protected from the elements is a full time operation and workers live in houses built amongst vines.

Traditional varieties including Cabernet Sauvignon and Chardonnay failed to fruit and were susceptible to termites.
