Hi Wendy:
World Showcase at Epcot is one of my favorite places in all of Walt Disney World. I love being able to experience different food, drinks, and cultures, all in one magical spot.
I do not know of any official beer tour at Epcot at this time. However, nothing is stopping your husband and father from strolling around the World Showcase Pavilions and grabbing their favorite beer from around the "World." While selections are subject to change, I've enjoyed (spread out over many trips, of course) Moosehead at the Canada Pavilion, Kirin at the Japan Pavilion, Tsing Tao at the China Pavilion, Sam Adams at the American Pavilion, Guinness at the UK Pavilion, an Oktoberfest brew at the Germany Pavilion, and many others along the way.
For restaurants featuring great beer selections, check out
Raglan Road Irish Pub located in Downtown Disney,
Rose & Crown in the UK Pavilion at Epcot,
Big River Grille & Brewing Works in
Disney's Boardwalk, and
ESPN Club, also in Disney's Boardwalk.
Enjoy your vacation.
