As snow fell over Billings, a group gathered around a fire pit outside 105 Brewing in the Heights to partake in a unique celebration on St. Patrick’s Day weekend: Bierstacheln, or "beer spiking." This centuries-old German tradition involves inserting a red-hot iron into a glass of dark beer, which heats the drink, creating foam and transforming its flavor.

Travis Zeilstra, founder and head brewer at 105 Brewing, expressed enthusiasm for the event, indicating it was something he had always wanted to offer and aspired to make it an annual custom. The practice originated centuries ago when drinkers would heat their cold beer with a heated poker from their stoves or fire pits, improving their drinking experience during winter.

“Adding the hot poker changes the flavor components, warms up the beer, creates a caramelized sugar or a toasted marshmallow flavor,” explained Zeilstra. This new experience makes each glass feel different.

Many patrons, including Heights residents Brenna Moloney and Anne Genereux, were eager to try out the beer spiking. They described it as a cozy and interesting activity, especially on a snowy winter day. “It was cool. It was super fun,” Genereux remarked after tasting the altered flavor.

Beyond the curiosity of beer spiking, the brewery has emerged as a vital community hub. Local residents Ron Pitsch and Duane Dittmer emphasized the significance of having a nearby gathering place, enhancing community ties. “It’s just so great to have this and to support the businesses here,” said Pitsch.

The establishment also hosts trivia nights, dance events, and community meet-ups, including a veterans group that gathers weekly. “The 105 really makes it happen for us,” said Pete Herzog, a member of the veterans group, appreciating the brewery’s accommodating nature.

Zeilstra noted that the brewery has been well-received by the Heights community since its opening, expressing gratitude for their support. As people partake in the ancient tradition of beer spiking, the sense of community and tradition at 105 Brewing continues to grow warmer.
