Drink Prosser Runs 16 Days. Two Saturdays Do Most of the Work.

Through Monday, Nov. 16, a wine club card from one Prosser winery gets club treatment at every winery taking part in Drink Prosser. The promotion runs Nov. 1 to 16, and the organizers bill it as two weeks with 21 wineries. In practice, tasting room hours narrow it down. Saturday is the only day of the week when every participating winery with posted walk-in hours has its doors open. The window holds two Saturdays, Nov. 7 and Nov. 14, and the first one also has a sparkling wine tasting at the Walter Clore Wine & Culinary Center.

What the Card Actually Gets You

The rules fit on an index card. Your "home" winery, where you already hold a membership, issues your club card. You bring that card to the other participating wineries and keep it with you to receive the perks. Each winery chooses its own offer. Drink Prosser lists waived tasting fees, case discounts, inside scoops and limited-release wines as the perks guests are likely to see. When you hand the card in at the last participating winery you visit, you're entered in a drawing for a wine basket.

Because each winery sets its own perks, a stop at Mercer Wine Estates may look nothing like a stop at Cork & Taps. Hours work the same way, and hours decide how many of those stops one afternoon can hold.

The Week Has a Shape

This is every participating winery with its posted tasting days, sorted by street. Where a winery's own site lists hours, those are used. Otherwise the hours come from its profile in the Drink Prosser winery directory.

On Tuesday, Nov. 10, seven of the 21 have posted walk-in hours: Airfield Estates, Alexandria Nicole, Coyote Canyon, Martinez & Martinez, WIT Cellars, Gård and Barrel Springs, and Barrel Springs is only open for its two-hour weekday window. Wednesday adds Evergreen, Tirriddis, Mercer and McKinley Springs. Thursday brings in most of the rest. By Saturday, everything with posted walk-in hours is open, including Barrel Springs from 1 to 5 p.m. and Daven Lore from 11 a.m. to 5 p.m. Sunday is close, but Barrel Springs lists no Sunday hours.

That makes the program's core two Thursday-to-Sunday stretches: Nov. 5 to 8 and Nov. 12 to 15. Monday, Nov. 16 is the last day of the program, and it's a better finale than you might expect. Airfield, Alexandria Nicole, Bunnell, Coyote Canyon, Enodav, Evergreen, Gård, Martinez & Martinez, Tirriddis and WIT all post Monday hours. Bunnell's flights and dining run until 8 p.m. on Mondays.

Some listings disagree with each other, so call ahead for these. Smasne's visit page shows two Prosser schedules, and only one includes Thursday. Desert Moon doesn't post tasting room hours online. Evergreen's directory profile carries two different hours blocks. Barrel Springs' seasonal schedule runs only through Thanksgiving weekend, so its November hours are among its last of the year.

Nov. 6 and 7 Stack Three Things in One Neighborhood

The first full weekend of the program lines up with two other events, and they help each other.

Prosser First Fridays features select wineries staying open until 8 p.m. The Nov. 6 lineup is Gård Estate Wine, McKinley Springs and Tirriddis Sparkling Wines. On a normal Friday, most of the list closes between 5 and 7 p.m., so those three give a Drink Prosser cardholder an evening window. WIT Cellars also lists a Drink Prosser event at its 505 Cabernet Ct. tasting room on Nov. 6.

Saturday, Nov. 7 is the bigger day. Every walk-in winery on the list is open, and Bubbles & Bites returns to the Walter Clore Wine & Culinary Center. Tour Prosser says Prosser wineries will pour their sparkling wines, naming Tirriddis, WIT Cellars, DavenLore and Evergreen Family Wines among them, with bottles for sale to take home. Food comes from regional chefs at The Prosser House, Scratch Bakery, CG Catering and others. A $20 ticket covers entry, four scrip and a logo glass. Samples cost scrip, and you can buy more. Ticket sales stop at 300, and the event is 21 and over with ID. Daven Lore's event listing gives the hours as 5:30 to 10:30 p.m.

So Saturday has a natural order. Tasting rooms close between 5 and 7 p.m., and Bubbles & Bites opens at 5:30. A cardholder can use the club perks in the afternoon and finish at the Clore Center. Tour Prosser pitches the evening as a chance to stock up on local sparkling wine for holiday gifts and parties. Four of the named pourers are also Drink Prosser participants, so you can taste a sparkling wine at the event and go back to that tasting room on Nov. 14 with your card.

Planning a Loop by Street

Most of the list sits close together, which is why one afternoon can cover so much of it.

Port Ave. is the densest stretch. Desert Moon's tasting room is at 357 Port Ave., and the winery says it shares an outdoor space with Coyote Canyon and Martinez & Martinez. Cork & Taps at 236-D and Wautoma Springs at 236 Port Ave., Suite C are next door to each other. Both describe their locations as part of Vintner's Village. Both are open Thursday through Sunday only, so plan Port Ave. for a Thursday-to-Sunday day.

Cabernet Ct. and Merlot Dr. hold the next group. WIT Cellars places its 505 Cabernet Ct. tasting room in Vintner's Village. Bunnell, Evergreen and Thurston Wolfe are on the same court, and Airfield, Enodav and Smasne are a short hop away on Merlot Dr. Of the Merlot Dr. and Cabernet Ct. wineries, only Airfield and WIT post hours every day, so these streets work best Thursday through Monday.

Lee Rd. is its own stop. Alexandria Nicole and Narratif share 2880 Lee Rd., and Alexandria Nicole says its tasting room is near the Port of Benton's Wine and Food Park. Mercer Wine Estates is just down the road at 3100 Lee Rd. On Wine Country Rd., Gård is at 2258 and Tirriddis is at 2140-B, next to the Clore Center, which makes Tirriddis a handy last stop before Bubbles & Bites.

The rest need a car and some planning. Daven Lore is on S. Davlor PR SW, McKinley Springs is on Frontier Rd., Barrel Springs is on N Gap Rd., and Above the Curve is on W. Island View PRNW. Above the Curve takes appointments only, and Daven Lore takes weekday visits by appointment. Daven Lore recommends appointments even on weekends, though they aren't required.

The Weekday Version, Including Veterans Day

Weekdays still work for a shorter loop. The Prosser Chamber of Commerce lists the Veterans Day Parade on Wednesday, Nov. 11. On Wednesday, Mercer, McKinley Springs, Evergreen and Tirriddis join the seven wineries open on Tuesday, which is enough for an afternoon after the parade. On Thursday, Evergreen stays open until 8 p.m., and Coyote Canyon and Cork & Taps both post closing times of 7 p.m.

If you don't belong to any of these clubs yet, the Drink Prosser page says joining any participating winery makes you eligible for the program's benefits. Each winery sets its own membership terms, so ask the winery directly before you join.

After Nov. 16

Thanksgiving in Wine Country runs Nov. 27 to 29, 2026, with tasting flights, food pairings, live music and holiday specials across the valley. The Chamber lists Small Business Saturday and the Princess Theater Christmas Market on Nov. 28. Downtown's Christmas Tree Lighting is Friday, Dec. 4 at Depot Square, 1230 Bennett Ave. Lighted trucks arrive around 6 p.m., and the tree is lit at 6:30.

Visiting wine country in November is one of the perks of living in Prosser, and I'd love to hear which tasting room on the list you liked best.
