Midnight rambler

For a relatively small mammal, River City’s Midnight Marmot sure gets around.

The downtown brewery celebrates its seasonal imperial stout with the third annual International Marmot Beer Festival on Saturday from 3 to 8 p.m.

It will feature seven variations on the rich black elixir using ingredients from around the globe, including:

– Oranges and star anise from China.

– Coconut from the Pacific Islands.

– Vanilla and coffee beans from South America.

– Thai chilies.

– Mint leaf and cocoa nibs from Ecuador.

– Cognac and French oak chips.

– A wine barrel-aged version with Washington raspberries.

There’s also a grand cru blend of last year’s regular Marmot, its raspberry/oak, Indian curry and Madagascar vanilla versions plus Congratulator doppelbock.

Your ticket get s you 2-ounce samples of all eight beers, plus a 12-ounce pour of your favorite, for $25 in advance (at the taproom) or $25 at the door.

Food will be provided by the Nick’s Shameless Sausages truck.
