"This was my 42nd harvest, and this was the worst loss I have ever had." Ron Bitner said that to the Capital Press on October 1, a day after his crew finished picking. His harvest at Bitner Vineyards ran September 29 and 30. Two days. On the 32 acres he manages, harvest usually takes about six weeks.
A few miles away on the same bench above the Snake River, James Nederend of Koenig Vineyards and Scoria Vineyards started picking in mid-August. That is five to six weeks earlier than usual, and he expects to finish by mid-October. Both stories come from the same growing season and the same corner of Caldwell. Together they explain why the Sunnyslope Wine Trail runs on a different calendar this October. For most of the trail, crush season has come and gone. What's left for the rest of fall happens at the tasting bar.
One storm, one road, very different outcomes
A heavy hailstorm in late July damaged wine grapes and other crops in parts of the Sunnyslope area. It hit some blocks hard and missed others, so the season looks very different from one vineyard to the next.
| Vineyard | What 2026 looked like | Source and date |
|---|---|---|
| Bitner Vineyards | About 85% grape loss, two-day harvest ending Sept. 30, very few whites | Capital Press, Oct. 1, 2026 |
| Williamson Orchards & Vineyards | July storm opened clusters on the windward side and damaged upper canopies, so the white crop is smaller than planned | Capital Press, Oct. 1, 2026, and Williamson's news page |
| Koenig and Scoria | Picking since mid-August, mid-October finish expected, whites looking healthy | Capital Press, Oct. 1, 2026 |
| Emerald Slope Vineyard | Harvest about two weeks early at what its manager calls the hottest site in the Snake River Valley | BoiseDev, Sept. 23, 2026 |
Nobody has published a region-wide yield total for 2026 yet. The reporting so far is farm by farm, and that is the level where these numbers hold up.
Why the picking started in August
According to BoiseDev, harvest in the Snake River Valley AVA usually runs from early September through October. Sophia Martin, vineyard manager at Emerald Slope Vineyard, traced this year's early start to the winter. "There was not a lot of water hydration for the plant, and then combined with a super warm March, it just made everything wake up earlier, so our bud break was about two to three weeks earlier than normal," she said. Warm weather through spring and summer kept the grapes ripening ahead of schedule.
Nederend told the Capital Press the summer was "hot, but not too hot," and that early fall kept the good conditions going. He also said "smoke was a bit of a concern this year" and that he's "a little worried about the reds being slightly lighter." He expects the reds to age well.
So an early start and a storm-shortened crop took the harvest out of its usual October slot. If you were planning to see picking on a mid-October Saturday, most of the trail has already finished.
Where you can still put your hands on the fruit
Huston Vineyards is the clear exception. Its Harvest Party runs Saturday, October 10, from noon to 5 p.m. Huston's event page says this year's fruit comes from the winery's "very first Cabernet Sauvignon block." Morning Pickers team up to harvest the block and compete for the most fruit. Grape Stompers arrive at noon to watch the fruit reach the crush pad, then winemaker Jacob walks guests through destemming and fermentation before a winery tour. Papa Bear's BBQ will be on site. Every guest gets a complimentary glass of Huston wine and a Harvest logo glass to take home.
In most years, a picking day on October 10 would be in the middle of harvest. This year it's one of the last chances on the trail to see fruit come in.
The calendar after crush
With the grapes in, the tasting rooms have moved on to releases, after-hours nights and the late-November barrel weekends. Here are the dated events posted on winery calendars as of early October:
- Oct. 10, noon to 5 p.m. Williamson's free Wine Warehouse Mini-Market. Sawtooth hosts Pop-Up Flowers by HappiGirl2 from 11 a.m. to 2 p.m. the same day.
- Oct. 15, 5:30 p.m. Williamson After Hours: Paint & Sip. More sessions follow on Nov. 12 and Dec. 10.
- Oct. 17 Huston's Brave & Bold Red Release and Little Brown Stein Watch Party, 11 a.m. to 5 p.m., followed by Sippin' in the Sunset from 5 to 8 p.m.
- Oct. 22, 6:30 to 8:30 p.m. "An Exhibit to Die For," a murder-mystery dinner at Williamson.
- Oct. 23, 6 to 9 p.m. Winery After Hours at Ste. Chapelle with Lindzey Autumn, no ticket required.
- Oct. 24 A full day at Sawtooth: Pop-Up Flowers from 11 a.m. to 2 p.m., a Tuscany Tour & Chocolate Tasting pop-up from noon to 3 p.m., and Harry Potter trivia from 6 to 8 p.m.
- Oct. 25 and Oct. 30 to 31 Fujishin Family Cellars lists wine-glass-charm making with Kass & Co. from noon to 5 p.m., then a candy-and-wine pairing with Free Dog from noon to 6 p.m. The events page leaves off the year, so check before you drive out.
- Nov. 27 to 28 Barrel weekend. Huston pairs a progressive food-and-wine tasting with barrel samples from noon to 5 p.m. and adds a Saturday sparkling brunch from 10 to 11:30 a.m. Williamson's Fall Barrel Tasting runs noon to 5 p.m. both days, and the winery says its extras are still being finalized. Fujishin lists a curated tasting and charcuterie event Nov. 27 to 29.
Huston and Fujishin both close on Thanksgiving Day, November 26. Huston's November 21 fall release is for Reserve Club members only.
What a short crop means at the tasting bar
The hail shows up in what gets poured. Williamson says contract demand and low yields have kept it from making large lots of white wine for two seasons now. It has cut back the whites in its Traditional Tastings and paused new White Wine Club memberships. It had hoped the 2026 harvest would restock those whites, but says the July storm damage means it won't get the quantities it planned. Williamson went back to regular Wednesday through Sunday hours, noon to 5 p.m., starting September 30.
At Bitner, the small red harvest is headed for a rosé blend. "Normally we pick for a full-bodied red wine," Bitner said. He also credited a strong wine club with helping him keep his crew working on other jobs. The tasting room is mostly members-only, with a limited number of advance nonmember reservations on Fridays and Saturdays before 2:30 p.m. for groups of four or fewer. The 2026 season ends November 22. Its calendar lists acoustic guitar by Steve Fultz on October 10 and piano by Paul Roach on October 11 and 18.
If you're planning around the newest winery on the bench, Devil's Bedstead opened at 21500 Hoskins Road in June 2025 and keeps tasting-room hours Friday through Sunday, noon to 5 p.m. Gem 73, the 15,500-square-foot project on Chalk Hills Lane, still says "Opening Summer 2026" on its own site. Check that page before you add it to a route.
The farm stops on the same back roads
The orchards are on their own fall schedule. Williamson's u-pick season this year was cherries and apricots, and its trees were picked clean by June 25. For fall fruit and pumpkins, look a little further along the trail.
- Lovely Hollow Farm, 18252 Chicken Dinner Road: Floral Pumpkin Night on Oct. 6 from 6 to 8:30 p.m., Sunset Flower Picking & Pumpkins on Oct. 7 from 5 to 8 p.m., Pumpkin Days on Oct. 10 and 11, a Kids Market on Oct. 17, and the last Pumpkin Days + Marketplace on Oct. 18, all daytime events running 10 a.m. to 4 p.m.
- Cherry Hill Farms: Fall Festival and an eight-acre corn maze with a pumpkin patch through Oct. 31, plus Apple Days on Oct. 23 and 24 from 10 a.m. to 5 p.m. with apple u-pick and cider pressing.
October 10 has the most going on in one day. You can catch the Cabernet harvest at Huston, pumpkins at Lovely Hollow, the free Mini-Market at Williamson, and Steve Fultz on guitar at Bitner if you have a reservation. For a quieter visit to the tasting rooms, Thanksgiving weekend is when Huston and Williamson pour from the barrel, and those barrels hold the 2026 wines from the growers quoted above.
