What are the best heat risk mitigation strategies out there?

I'd say it's vital to adopt a targeted approach. Start with no-till farming to keep your soil's structure and moisture intact – it's a simple but effective way to help your vines during heat waves.

When it comes to watering, precision is key. Drip irrigation is the way to go. It delivers water right where it's needed, at the roots, and helps you avoid wastage. Pairing this with soil moisture sensors can really dial in your irrigation, making sure your vines get water exactly when they need it.

VPD monitoring, or keeping an eye on the vapor pressure deficit, is something I wouldn't overlook. It sounds technical, but it's essentially about understanding how moisture and temperature interact in your vineyard. Getting this right can significantly impact grape quality, especially in hot conditions.

And don't forget about choosing the right grape varieties. Opting for types that can handle the heat will make your life a lot easier. It's about adapting to the climate you're in, rather than fighting against it.

So, it's all about being strategic – no-till farming, precise irrigation, savvy VPD management, and picking the right varieties for your climate. Stick to these, and you'll be on the right track.
