Quad on Oak

Quad on Oak is River North Brewery’s first seasonal beer.
For this beer, River North’s brewers crafted a traditional Abbey-style Belgian Strong Dark Ale, then aged it on toasted American oak. Wood-aging lends dry notes of vanilla and coconut, providing a perfect balance to the rich, malty base of a Quadrupel.
“One of our favorite beers we brew is Unified Theory, an oak-aged imperial witbier. The subtle, toasted oak character complemented that beer so well, we‘ve been anxious to create a new oaky twist on another Belgian style,” Head Brewer Matt Hess said. “That’s how we conceived the idea for Quad on Oak.”
