City and Country brewers used a piece of evergreen on their alestake (a pole) announcing they had beer to serve. This beer celebrates the other "green" in brewing: hops, which are used for aroma, flavour, bitterness, and preservation. Those who like hoppy beers, like this India Pale Ale (IPA), celebrate their releases and drink them fresh, as patrons seeing an evergreen bough on the brewer's alestake did in the past. That's when IPA becomes IP Yay. Cheers for Alestake and Evergreen IPA!
