Lemoyne-based Scotzin Bros., which has been open only two days a week since the 1980s, will make the change Aug. 1.

“We were planning to open full time in 2013, but a number of factors came together that prompted the decision to go live sooner rather than later,” said Patti Adami, a partner in the store. “One of these factors was finding the right people, or rather, they found us. We now have a sufficient complement of very knowledgeable brewers — both beer and winemakers — to be able to staff more hours.”

Scotzin Bros. opened as an appliance business. Paul Scotzin and his brother, John, began making wine in the 1960s. Carboys of wine were always bubbling in the back of the store.

Over time, the carboys outnumbered the appliances, and the winemaking business came into full swing.

The supply store moved to its present location on North Fifth Street in 1986. When Paul died in 1988, his stepson, Tom Snedden, took over and significantly expanded the business to include beer supplies.

Despite growing competition from online suppliers, Scotzin Bros. has seen business increase nearly 35 percent during the past five years, Adami said.

“We try to maintain a large inventory and promote the in-store experience, including having knowledgeable sales people, classes and even tasting samples,” she said.

Earlier this year, York County-based Mr. Steve’s Homebrew and Wine Supplies opened a location in Lower Allen Township, not far from Scotzin Bros.

“We feel it can only increase market share for everyone,” Adami said about the competition.

Home brewing has become very popular with growth in craft beer.

Along with the change in hours, the store began accepting credit cards two months ago. The new hours will be 10 a.m. to 6 p.m. Monday through Friday, 10 a.m. to 5 p.m. Saturday and noon to 5 p.m. Sunday.

On Sundays, the store will run what is being called “Sunday School” with short classes and instruction on various aspects of home brewing.
