By midyear, Seventh Son Brewing in Columbus' Italian Village will have doubled its beer production and begun providing a new rooftop patio for patrons to enjoy in any weather condition.

Although Seventh Son's expansion at 1101 N. Fourth St. is under construction, the taproom continues to remain busy. By the time the brewery opened at 3:30 p.m. Jan. 25, the bar was nearly full and guests had claimed their tables to do work while drinking one of the many brews made in house.

Seventh Son was the third stop on the #ThisWeekBreweryTour for ThisWeek staffers.

In addition to the dozen or so beers offered daily, Seventh Son has an alcohol-based slushy called Paloma that can top a beer of your choice (for a concoction called Iceberg), said Seventh Son co-founder Collin Castore.

While on a trip to Oregon, Castore visited a bar that topped Natural Light beer with a generic margarita-mix slushy, he said. Although the drink was refreshing, Castore said, he knew he could make an elevated version of the drink in the taproom.

The Paloma is most popular in the summer, Castore said, but the drink is available year-round.

"We tried to shut down the slushy machine in the winter, and we actually had, like, a minor revolt," Castore said.

By the end of spring, Seventh Son expects to have its 1,500-square-foot expansion completed, adding a larger brewing space to increase production of kegs that are sold to restaurants and other locations throughout Columbus. In addition, the expansion is expected to increase the number of customers who can relax in the taproom or a new patio space that has a retractable glass roof.

The retractable-roof idea came from Mario Batali's Eataly in New York City, Castore said. Seventh Son was able to construct a similar retractable roof that the marketplace uses so the rooftop patio could be used in all weather conditions, he said. The patio also will have a bar on one end so guests can keep their glasses full.

A different food truck is parked at Seventh Son each night, Castore said. The food trucks allow the brewery to stick to making beer while the food trucks focus on the accompanying dishes, he said.
