More than 35 different brewers will serve craft beer at the annual Mile Marker 68.3 Bier Fest Saturday, April 29, in an effort to raise funds to help clean the Missouri River.

August Brewing Company and John G’s Bier Deck owner Terry Heisler said he has been adding new brewers to the event’s repertoire every day since the date was announced. This year, the Bier Deck will host more brewers than the festival ever has, he said.

All proceeds from the Bier Fest will go toward the Missouri River Relief project. Heisler said keeping Missouri’s river water as clean as possible and educating Missourians about river cleanups is important for the environment and for brewers.

The relief project will be cleaning the river at a separate event Saturday, April 8.

Heisler said the fundraiser will help fund the cleanup after it takes place. He said the volunteers who help clean up the river have pulled 10 to 15 tons of waste out of the river at past cleanups.

General admission tickets to the festival will allow entrance to the Bier Deck from 1-5 p.m. Special VIP tickets will allow entry at noon and end at the same time.

A total of 150 VIP tickets will be sold on a first-come-first-serve basis. A designated driver ticket also is available for a lower price.

Free beer tasting, live music and commemorative glasses are included with tickets.
