Zairona Ale was a strong, very rare alcoholic beverage that was illegal in the Galactic Empire. Its source was somewhere in the Forbidden Zones.
Ace Azzameen got a bottle of Zairona Ale after a battle with Loose Cannon pirates shortly after the Battle of Hoth. Emon Azzameen mentioned that his father gave him a swig when he was a child, so he could get some hair on his chest. As he put it, it put hair on his chest, legs, arms, and every other part of his body. Zairona Ale might have been sold aboard the casino/resort space station, the Dunari's Rest, as its drinking chit showed a drink on it that was similar in appearance to the illegal alcoholic drink.
