What is ThermacultureTM?

Thermacultureā„¢ is a revolutionary treatment service that applies heat to crops with astounding results. Use Thermaculture to:


  • Increase fruit set and yields even in cold, wet weather
  • Improve wine quality by increasing flavonoids including antioxidants and phenols.
  • Decrease overall pest control costs by disrupting insect and fungal development
  • Reduce moisture to prevent bunch rot and fungal damage after rains
  • Add BRIX late in season

The flavor characteristics of the wines from treated grapes were in my view noticeably better. In finished wines these early stage advantages would likely improve with aging to an even greater degree.

In total we decreased our pest control spray passes in half...Each Thermaculture pass cost about 1/4th of the pesticide pass it replaced with less time wasted mixing chemicals and doing fill-ups.

During the 2014 season and were amazed to see up to 40% more berries per bunch in fruit set over matching control blocks. We also saw better color, healthier looking, greener vines and deeper colored grapes at harvest.
