Wine producers in Portugal’s Alentejo region are increasingly relying on nighttime operations to harvest grapes, a strategic shift aimed at preserving quality amid soaring temperatures linked to climate change.
The move to night harvesting allows estates to pick fruit during the coolest hours, protecting the crops from the intense solar radiation and heat spikes that have become more frequent in recent years. By avoiding the peak daytime heat, winemakers can maintain better acidity and aromatic profiles in the grapes before fermentation begins.
This adaptation reflects a broader trend among European vintners as extreme weather events threaten traditional agricultural schedules. For Alentejo estates, the logistical challenge of coordinating labor under artificial lighting is now considered a necessary investment to safeguard the region’s reputation for high-quality wine production.
Smart move, honestly. Better to invest in artificial light than lose the crop entirely. Alentejo wine won’t taste the same otherwise.
The logistics of this must be insane. Lighting entire vineyards at night adds so much cost. Who pays for that extra electricity?
I tried night picking last year. It’s exhausting but the grapes tasted absolutely pristine compared to the scorched ones from afternoon harvests.
Is this just a temporary fix though? If temperatures keep rising, will night harvesting even be enough to save the vintage?
My grandfather used to wake us at dawn. Now we work in the dark. Climate change is real and it hits us hard every season.
