If you spend any amount of time in Milwaukee, chances are you'll imbibe in a Lakefront Brewery beer, whether it's from a Pale Ale quarter barrel at a party or to wash down a piece of fried perch with a Riverwest Stein.

Lakefront's Pumpkin Lager is a seasonal offering, but one of the company's most famous products. It's the world's only pumpkin lager, whereas other breweries make pumpkin ales because they take less time. (A batch of Lakefront lagers for four weeks.)

"This extra time gives the Lakefront Pumpkin Lager a deep, smooth richness that no ale can match," says Lakefront Brewery's Orlando Segura.

In 1989, Lakefront co-owner Russ Klisch found a pumpkin beer recipe that Thomas Jefferson homebrewed at Monticello. Back then, barley and hops were hard to come by, but pumpkins and squash were plentiful, so pumpkin beer was more common.

"Lakefront Pumpkin Lager was one of the first pumpkin beers in the United States since Prohibition, creating an entirely new category of craft beer," says Segura.

Jefferson's recipe inspired Klisch to create Lakefront's signature recipe that contains real pumpkin mash. The mash contributes to the brew's signature foamy head that's meant to be similar to the whipped cream on top of a slice of pumpkin pie.

All of the spices used in the beer -- nutmeg, cinnamon, clove and allspice -- are purchased from The Spice House, a Milwaukee institution that's been in business for 50 years. The malts are imported directly from Germany.

Although a popular autumnal beverage, some drinkers say Lakefront's Pumpkin beer -- as well as their Holiday Spice Lager that comes out in time for the December holidays -- isn't meant for consuming more than one or two at a time.

"Pumpkin beer is perfect when you're really going out for just 'one,'" says self-described "Bay View bar fly" Mike Fedderle. "It has so many flavors which is good, but can be too much of a good thing, too."

Pumpkin Lager is brewed to complement fall foods and holiday dinners, and is intended to enhance the flavors of turkey, chicken, ham or vegetables.

"Just as Thomas Jefferson led the way in building the country with a glass of beer settled firmly in his hand, Russ Klisch and Lakefront Brewery continues to advance the art and craft of brewing with innovative and traditional styles of beer," says Segura. "It's pure Milwaukee genius."
