Agrotherm XT

Thermal treatment

Heat up your bottom line

Sufficient heat at the right time is the key to grape soundness and for a high quality wine in satisfactory quantities.

The Thermaculture™ treatment is based on the principle of a short-term heat shock in which air which has been heated to 150°C is emitted on both sides of the plant by two gas-operated fan heaters with a wind velocity of 40 to 60 km/h. This takes place in a fraction of a second while the tractor-drawn AgrothermXT passes along the rows of vines and – of course - it does not cause any damage to the vines. The heat shock does however have several positive effects on the grapes and the foliage.

Agrotherm XT

Regular applications - from bud break, throughout the growing season and up until harvest - have shown considerable advantages in comparison with vines that have not been thermally treated.


Sustainability is really important and gaining more and more visibility. The heat treatment with AgrothermXT could be a great part of that story and one that consumers would be very responsive to. It will be a part of our future promotional activities if successful.

We couldn't be happier with the results we saw. Not only did we get higher fruit set and yields on our Pinot Noir, Chardonnay and Cabernet Sauvignon, but we cut our pest control costs significantly from what was normally used in our vineyards. Finding sustainable solutions like Thermaculture is very important to our mission at Foley.
