Dutch Bros. fans — known as the Dutch Mafia — can pick up their favorite brews from the new drive-through Prosser shop.

It opened July 2 at 119 Merlot Drive, just off Interstate 82.

The 16-by-30-foot stand also includes a 17-by-17-foot storage area.

Erin and Ryan Bates own the Prosser and Sunnyside franchises.

On the first day in operation, drinks were $1 apiece and all proceeds — $6,455 — were donated to Mustangs for Mustangs, a nonprofit that offers emergency assistance for housing, primary transportation, medical needs, utility and rental assistance and personal safety issues. The group serves anyone who attended Prosser schools or lives in Prosser and their immediate family members

“The community has already been so supportive of Dutch Bros,” Erin said. “We’re grateful for the opportunity to give back to those who need it most.”

Banlin Construction of Kennewick was the general contractor.
