If there was one thing winemaker Jef Stebben learned during the 2026 harvest at Aridus Wine Co., Willlcox, Ariz., it was to expect the unexpected. An early burst of heat, dramatically shifting monsoon weather and grapes that stubbornly ignored their usual ripening schedules turned this year’s harvest into a fast-and-furious exercise in adaptability. The reward? A crop that was up in volume, a crew that pulled together under pressure, and a collection of wines that has Jef excited about what lies ahead.

Harvest began July 14 with Chardonnay, the one variety Aridus purchases rather than grows itself. Sauvignon Blanc was the first estate-grown fruit to arrive, on July 30\. From there, the season moved at a remarkable pace, with over 100 tons of estate grown grapes harvested-an increase of about 7% from 2025\. The last fruit harvested came in on September 9, kicking off the work of fermentation, racking and aging in the following weeks.

## A Season That Defied Expectations

Early heat appeared to accelerate the growing season, setting the vines on a trajectory that seemed almost two months ahead of expectations. Yet the varieties did not mature in their customary order. Sauvignon Blanc, which historically comes in early, initially appeared to be lagging behind red varieties such as Malbec and Petite Sirah. Then, almost at the last minute, it caught up.

“We thought we were going to be picking red grapes first,” Stebben explains. “Instead, the whites matured enough that we picked all of them before the first red came in. It was completely unexpected.”

Viognier also challenged expectations, requiring the team to pick Sauvignon Blanc, then Viognier, and then return to harvest additional Sauvignon Blanc.

The unusual sequence was only part of the story. As temperatures climbed, grape sugars rose quickly, while other indicators of maturity did not develop as expected. Seeds remained greener than usual, stems did not lignify normally, and skins failed to soften in the familiar way.

“Grapes don’t always follow the rules,” Stebben says. “The stems, seeds and flesh can all mature at different rates. This year, the chemistry was changing so quickly that we really had to taste the fruit and pay attention to what it was telling us.”

The lesson was clear: relying on the usual visual and chemical indicators alone could have led to missed opportunities in deciding when to pick.

Stebben has a hypothesis about one possible contributor to the unusual growing season: exceptionally high ultraviolet (UV) radiation. Throughout the growing season, he recalls, weather services issued warnings about extreme UV levels, at times advising people to limit their exposure outdoors. He wonders whether the intense solar radiation may also have affected the vines.
