While the mercury is saying it’s still summer, the draft list at McGillin’s Old Ale House is forecasting fall drinking. Seems the city’s oldest continuously operating tavern isn’t wasting any time rolling out the barrels for its Oktoberfest celebrations. This week the bar started tapping its stash of Märzenbier-style suds and other autumnal quaffs. Joining Stoudt’s Fest beer, Flying Fish's Octoberphish, and Yuengling's Oktoberfest, McGillin’s is also pushing a pumpkin ale from Saranac. And since drinking men and women can’t live on beer alone, the menu’s been updated with Bavarian beer-sipping companions like German style grilled sausage platters, with bratwurst, knockwurst, red cabbage and warm German potato salad; grilled pork loin with sweet and sour cherry sauce, braised cabbage, apples and potato dumplings; and Kasebrotchen, chicken breast topped with German style spread of ale, brown mustard, and sharp cheddar cheese that’s baked to a bubbly finish.
