Heavy Seas & Tröegs Collaborating On Deeper Dive

I’m always excited to bring you new collaboration beers, and today I have a good one coming soon from Heavy Seas Brewing in Baltimore, Maryland. This is Deeper Dive, and it will be an imperial oat stout brewed in collaboration with Tröegs Independent Brewing in Hershey, Pennsylvania. The beer will swim in at a deeper 9%-AbV, and look for Heavy Seas Deeper Dive to be packaged in these 12-oz bottles. Stay tuned for full release details.

This 26 Aug 2025 update from Heavy Seas:

Deeper Dive will be an exclusive offering available in our upcoming Frozen Seas Variety 12pk (releasing in the October timeframe), and artwork is still to be finalized.

About Heavy Seas Brewing:

Heavy Seas Beer was founded by Hugh Sisson in 1995 and has grown to become one of the most respected and award-winning craft breweries on the East Coast. As the first pub brewer in Maryland, Hugh was responsible for the legislation that made brewpubs legal in the state in 1987. Now over three decades later, Heavy Seas celebrates its 28th year of brewing independent craft beer in Baltimore. The brewery continues to expand its product portfolio, now producing 22 different beer styles, and distributing to 15 states and Washington, D.C. Heavy Seas was named Beer Connoisseur Magazine’s 2017 Brewery of the Year.

It all started in 1980… Hugh Sisson, a Maryland native, theater grad school major, and all-around good guy, joins his family’s restaurant & bar, “Sisson’s” located on Cross Street in South Baltimore.
Craft beer wasn’t even on the radar back then. But Hugh quickly recognized that to run a business, you need to do something to be different.

Light bulb moment: “What if we turned Sisson’s into a brewpub and brewed our own beer?”
Solid plan, right? Problem: Brewpubs weren’t legal in Maryland at the time. 

In 1987, Hugh worked with Maryland legislators to draft a bill to legalize brewpubs in Baltimore City – the bill passed on the first attempt. Fast forward to 1989, “Sisson’s” becomes the first brewpub in the state of Maryland. 
After  the brewpub scene for a few years, Hugh felt the need for a bigger stage (theater pun intended). In 1994, he left “Sisson’s” for his next business venture… and the rest, friends, is nothing short of Maryland craft beer history.
