Bratwurst, lederhosen and imported German brews make their return to the shores of Lake Washington this weekend for the fourth-annual Kirkland Oktoberfest, which may be the last Oktoberfest held solely at Marina Park.

The event has doubled in each year of operation, up to around 10,000 visitors last September, and while organizers don’t expect attendance to double this fall, they’re aware Oktoberfest is growing up.

“We have pretty much maxed out our space in Marina Park,” said Rob Butcher, the festival’s creative director.

With a sellout crowd of more than 10,000 expected this weekend, organizers are planning an expansion to nearby Heritage Park, which is much larger and includes additional parking spaces.

“[Oktoberfest is] just something that people in the community have wanted for the better part of a decade,” Butcher said. “It’s something that’s been brewing around, but never came into fruition until four years ago.”

The organizers are largely made up of the same group to organize Summerfest, which takes over the same area of the downtown waterfront.

This fall, the festival will feature more of what has made Kirkland one of the largest ‘authentic’ Oktoberfest celebrations in the Pacific Northwest.

The beer list includes six German breweries, and beers and ciders from 14 northwest breweries — including Kirkland’s Chainline and Flycaster microbreweries and Redmond’s Postdoc, Hi-Fi, Bushnell and Black Raven. The list also includes Woodinville’s Sumerian, 20 Corners, Triplethorn and B Side, and Bothell’s McMenamins Anderson School.

The festival features a handful of German- and beer-themed bands, including S-Bahn, which will visit 12 northwest festivals this fall. Music will be on two stages: one under the pavilion, and one in the northeast corner of the parking lot.

Wiener dog races are scheduled for 1 p.m. on Sunday afternoon on the south side of Marina Park, which will be open to all ages.

The festival runs from 4 p.m. to 11 p.m. on Friday, 11 a.m. to 11 p.m. on Saturday and 11 a.m. to 6 p.m. on Sunday.

Tickets for the Friday and Saturday slots are $20, with the Sunday ticket priced at $15. A weekend pass may be purchased for $30.
