Our coffee is specialty coffee, which means our coffee beans are top graded.  We focus on fair trade, small farm and small lot coffees, which allows us to bring some of the best coffees in the world to our customers at an accessible price point.  

Specialty coffee is more than just coffee, it is like fine wines. Each origin, region, and even farm brings its unique imprint to the bean. Roasting is part science and part art.  Our goal is to develop the best roast profile for each bean, each season, to garner the best flavor profile on offer.  The passion we have for each bag of bean is evident in our roasted coffee, and our enthusiastic staff.  We love coffee and we love talking about coffee - it is a magical bean in our view.

“We’ve been all over the globe, and a lot of people you meet, you meet in a coffee house.” —Catherine Bieri, co-owner, Three Fins… ."

Cape Cod Magazine


We are Ron Reddick and Catherine Bieri, owners of three fins coffee roasters.  We have both worked in the wireless technology industry for all of our careers.  We moved to Cape Cod after spending more than 12 years abroad helping mobile operators around the globe start up their businesses, but still found ourselves on the road in Europe and Africa. During that time, we explored many coffee houses and spent many enjoyable hours relaxing and taking in the the varying atmospheres.

After many long discussions on how we could enjoy the benefits of owning a house on Cape Cod and live and work there, we decided on coffee.  Good coffee houses are far and few to be found on Cape Cod, and thus three fins evolved. READ MORE
