Beer-lovers and chocolate-lovers, unite.

D.G. Yuengling & Son Inc. announced Tuesday its first-ever beer collaboration with Hershey’s.

Yuengling Hershey’s Chocolate Porter will be available on draft only, in select markets, while supplies last, starting mid-October.

“This is the first beer collaboration for the two iconic, Pennsylvania brands,” Yuengling announced in a news release. The new brew combines more than 300 years of the companies’ “respective mastery and rich heritages rooted in Pennsylvania,” the release states.

It will be available from Halloween through Valentine’s Day.

Yuengling is celebrating its 190th anniversary this year and Hershey its 125th.

LINDSEY SHUEY / STAFF PHOTOGRAPHER Bartender Stacy Balulis pours beer for a tour group at D.G. Yuengling & Son Inc., Pottsville, on Tuesday. Guests were able to sample a “mystery beer,” which is the brewery’s new Yuengling Hershey’s Chocolate Porter.

Yuengling will have a consumer first-taste event open to the public at 5 p.m. Friday at the brewery on Mahantongo Street in Pottsville.

“As the sixth generation of the Yuengling family, we have a 190-year history of listening to our fans and looking for new ways to deliver quality and memorable drinking experiences,” Jennifer Yuengling, vice president of operations and sixth-generation brewer for America’s oldest brewery and the nation’s No. 1 craft brewer, said. “We saw a unique opportunity to partner with Hershey’s.”

Yuengling spent nearly a year developing the 4.7% alcohol by volume porter. It combines Yuengling’s nearly 200-year-old Dark Brewed Porter recipe with the world-famous taste of Hershey’s chocolate.

Yuengling will continue to brew its dark porter.

The beer blends Hershey’s chocolate with caramel and dark roasted malts for “a smooth, rich and delightfully chocolaty finish.” The liquid pairs well with everything from barbecued and smoked meats, to cheeses and desserts.

The beer will be available in bars and restaurants in 14 of the 22 states that Yuengling reaches, including Pennsylvania, while supplies last.

The “Find Our Beer” link at www.yuengling.com will be updated in the coming weeks to detail where the new beer can be found.
