If you've got a rhubarb patch in your yard, Garrison Brewing will take any extras.

The south-end Halifax brewery is in the midst of creating a spring beer using stalks of the sour vegetable, most often associated with pies and muffins.

Garrison put a call out to the public on Tuesday for 200 to 280 kilograms of rhubarb. Already, people have dropped off fresh-picked rhubarb at the brewery's Marginal Road location, says brewmaster Daniel Girard.

"Just now, we got seven pounds. Yesterday, someone dropped off three pounds," he said.

The brewery is offering an in-store credit per pound of fresh, usable rhubarb, with leaves removed.

Girard is in the midst of creating a recipe for the beer, a process he says is stimulating and creative.

"We're playing around with it, you have to be flexible," he said.

The end result will likely about 1,600 litres of a Belgian-style beer, he said.

"Rhubeer has a nice ring to it, though," said Gerard.

Garrison wanted public involvement in the creation of the beer.

While rhubarb may seem an unlikely core ingredient, the brewmaster said past creations, including spruce, and honey and lavender beers, have proved very popular with customers.

"With the spruce, they were lined up at the door," said Gerard.

He says one of Garrison's most unusual flavour combinations was mint and apple.

"When you drank it, there was a cold sensation, a chill on the teeth when you took a sip," said Gerard.
