NORTHWOOD — Worth Brewing Co. is set to host its fifth annual Spring Bock Fest this Saturday.

“In our six years we’ve had great support from locals as well as the nearby communities. Mason City and Clear Lake residents have been supportive, but Albert Lea is probably our biggest market,” said owner and brewer Peter Ausenhus. “Spring Bock Fest is my favorite event of the year because it ushers in a warmer season and a lot of new brews.”

The brewer is a prime draw for tourists in the seat of Worth County, in addition to Diamond Jo Casino, Swensrud Park, the Northwood Theatre and quaint downtown merchants. Spring Bock Fest brings out the beer lovers — the types who seek quality in an alcoholic beverage over quantity.

Ausenhus said the event draws several hundred people to his brewery.

Worth Brewing will re-release the last of Pegret’s Choc-O-Bock, a collaborative brew between owners Ausenhus and his wife, Margaret Bishop.

“Her first brew,” Ausenhus said.

Tapped for one day on their sixth anniversary in March, it returns — a traditional malty German bock with a dose of cacao nibs for a hint of chocolate.

Father Filbert’s Nut Brown Mild is an English session beer with a malty, hazelnut flavor. Herminator Weizenbock rounds out the locally made brews.

Imported beer just for the Spring Bock Fest will be available from one of the world’s great brewing centers. Mahr’s Festbier from Bamberg, Germany, and Mahr’s ungespundet lager, an unfiltered beer in a gravity keg dispensed directly from the bar top, are slated make a rare appearance.

Worth Brewing also offers food, and on Saturday will feature homemade barley stew and spent-grain bread. Local bratwurst and red cabbage are available from noon on.

Big Ben & the Brians Concertina Band will perform late afternoon into the evening. They have become favorites at the Spring Bock Fest and the Northwood Oktoberfest.

The beer garden at Worth Brewing goes by its German name: biergarten. There will be bock fire poking in the biergarten after 5 p.m. A bock king and queen are to be crowned at 8 p.m. in the tap room. Royalty will be determined based on a short poem or essay on the subject: “Keeping the Bock Spirit Alive Year Round.” Submissions will be accepted all day.

The festivities run from noon to 11 p.m.
