You could savor on opening night a regulation four-ounce pour of sweetly malty, chocolaty Pig Iron Porter from Iron Hill or far hoppier local brews. You could listen to easygoing bluegrass combos or have spit-roasted pig and vinegary potato salad to the spirited marches of the Eine Kleine Oompah Band, with James Zoller of Birdsboro, Pa., playing a silver, double-B-flat tuba once used in Sousa bands a century ago.
Back before that tuba was even born, Philadelphia was one of the beer-making capitals of the country, with breweries lining Brewerytown to the west (where barrels were cooled in caves cut in the banks of the Schuylkill), and to the east the massive brewhouses of Kensington.
