Dunedin Brewery throws a beer party every time the seasons change (or in this year’s case, when it celebrates hallmarks like its 18th anniversary), and the fall is no exception. The only difference is that Oktobeerfest is one of its biggest, replete with two stages featuring live music spread over four days by big-name nationals along with smaller-scale local and regional acts (the 14th annual edition welcomes vet Bronx-born rapper Kool Keith and spacey jamtronic Athens, Ga. trio Ghost Owl among others), a 5K beer run, plenty of German cuisine (bratwurst, anyone?), and its own limited edition (only 1,000 available) 1-liter steins.Details: Dunedin Oktobeerfest, Oct. 2-5, 7 p.m. Thurs. & Sun., 6 p.m. Fri.-Sat., Currentz and Galbraith Group (Thursday), Jimkata with AJ Ghent Band (Friday), Ghost Owl with People’s Blues of Richmond and Legacy & Friends (Saturday), Kool Keith with Serotonic (Sunday), Dunedin Brewery, Dunedin, free admission all nights.
