What is woodpecker beer?

There is no such thing as "woodpecker beer." It's likely a misunderstanding or a made-up term.

Perhaps you were thinking of:

* Woodchuck Cider: This is a popular brand of hard cider made in Vermont, USA. It might be what you're recalling.

* A beer brand with a woodpecker on the label: Many beer brands use animals in their logos. Maybe there is a beer with a woodpecker you're thinking of, but there isn't a universally recognized "woodpecker beer."

If you can provide more context or details about what you're looking for, I might be able to help you further!
