Ron Bitner started picking grapes on September 29 and was done on September 30. On the 32 acres he manages in the Sunnyslope area, harvest usually takes about six weeks. A late-July hailstorm left him estimating an 85% loss, and he told Capital Press it was the worst of his 42 harvests.
Down in town that Tuesday night, Indian Creek Plaza held its last Farm to Fork Farmers Market and its last Tuesdays on the Creek concert of the year. So the summer ended in the vineyards and on the plaza in the same 48 hours. The weekly routine that filled downtown from spring through September is gone until next year. The rink doesn't open until November 20, so the seven weeks in between follow a different pattern.
For most of that stretch, the best weekend options are up on the Sunnyslope bench, south of town. The plaza takes over again once the ice goes in.
Through the summer, the plaza ran on a weekly loop. Farm to Fork brought more than 30 vendors every Tuesday evening, and the 20-week Tuesdays on the Creek series played alongside it. October has no weekly anchor. It has three separate evenings:
The plaza also tried something new this year to open the fall. Hay Day ran on October 3 and was billed as "a new Signature Fall event for 2026." It centered on the grape harvest, hops, pumpkins, seeds and antique tractors. The plaza built a downtown event around the harvest, and the harvest itself is going on a few miles south.
Two things set this year's Sunnyslope harvest apart. First, the season ran ahead of schedule. James Nederend, owner and winemaker at Koenig Vineyards and Scoria Vineyards, told Capital Press that a warm winter woke the vines early. He started harvesting in mid-August, five to six weeks earlier than usual, and expected to finish around mid-October.
Second, hail cut into the crop. KTVB reported that the July 23 storm brought golf-ball-sized hail and badly damaged an estimated 80 acres across Koenig and its nearby partner vineyards. Koenig expected about one-third to one-half of a normal harvest. The damage was patchy. Some blocks were hit hard while vines nearby came through fine. At Williamson Orchards & Vineyards, co-owner Mike Williamson said the storm split open clusters on the prevailing-wind side and damaged some of the upper canopy.
"I'm a little worried about the reds being slightly lighter," Nederend told Capital Press, adding that he expects them to age well and that his white grapes look healthy.
Put together, these mean the picking itself is nearly over. In a typical year, crush runs well into fall. This year, the hands-on harvest events are packed into the next couple of weekends.
The clearest chance to see a harvest up close is Saturday, October 10. Huston Vineyards at 16755 Chicken Dinner Road is holding its Harvest Party from 10 a.m. to 5 p.m. Guests pick Cabernet Sauvignon, stomp grapes, watch winemaking demonstrations, take a tour and have lunch. Each guest gets a complimentary wine glass. That same afternoon, Williamson runs a free Wine Warehouse Mini-Market from noon to 5 p.m. with local vendors and wine-club release pickup.
After that, the winery calendars move from the vines to indoor events:

October 24 is the busiest night of the month. It's also the night of the police hide-and-seek downtown, so on that Saturday a family could split between the plaza and Lowell Road.
Not every fall event in Caldwell involves wine. Cherry Hill Farms at 19125 Apricot Lane runs its Fall Festival and Corn Maze through October 31. It's open Wednesday through Saturday from 10 a.m. to 2 p.m., with evening hours from 5 to 8 p.m. that started October 1. On Halloween it closes at 3 p.m. Admission is $10.40, or $41.60 for a family of up to six, and children two and under get in free.
The farm's Apple Days fall on October 23 and 24, 10 a.m. to 5 p.m., with wagon rides, apple picking, cider-making, a complimentary apple and maze access. Tickets cost the same as regular admission. One of the farm's event pages still shows a 2025 date at the top. The farm's updated overview and its Caldwell events listing both give 2026.
By late November the harvest is in tanks and barrels, and two wineries open them up the same weekend. Huston closes on Thanksgiving Day, November 26, and its calendar lists the start of its annual Barrel Tasting Weekend on Friday, November 27. Williamson's fall barrel tasting runs November 27 and 28 from noon to 5 p.m. The winery says some details are still being finalized. A hail year makes these tastings more interesting than usual, since the wine in those barrels is all that came out of a short crop.
Starting November 28, Dunning Estates Winery at 19937 Vino Lane runs a weekend Christmas tree lot from noon to 6 p.m. through December 19. It has several fir varieties, cocoa and candy canes for kids, letters to Santa, and wine service in the white barn. Sawtooth's Christmas-movie trivia night is December 5, and Williamson's last Paint & Sip of the year is December 10.
The center of the calendar moves back downtown on Friday, November 20. That night the 2026-27 ice skating season opens on the plaza's ribbon, and tickets are already on sale. Sessions last one hour. Listed rates include taxes and fees:
The plaza says holiday sessions fill quickly. For skating questions, call the Lactalis Skate Shoppe at (208) 800-9032.
The Winter Wonderland Festival starts the same evening and runs November 20 through 22, from 6 to 9 p.m. each night. Downtown goes up under more than a million lights. There's an artisan market with more than 60 local makers, photos with Santa and Mrs. Claus, and horse-drawn carriage rides through downtown. From December 1 to 14, the Light the World Giving Machine sits on the plaza, and the listing states that 100% of donations go to charities.
The plaza's fall started with one new signature event and ends with another. Reindeer Games on Saturday, December 19, is described as a family day of skating, playful challenges and winter activities, and the plaza says more details are coming. The Dunning tree lot closes the same day. That makes December 19 the last date on this stretch of the calendar.
