Trivia

 * Prior to April 1, 2015, it could have been obtained through the purchase of a Homer Buddha, although the chance of success was very slim at only 1 in 500.
 * The income for this building is irregular, as the normal premium rate for a building that earns at 6 hour intervals is usually 175Cash and 18XP. However, the Duff Brewery instead earns 200 and 20, the normal rate of a non-premium building, which earns at 12 hour intervals.
 * It shares this trait with the Lemon Tree, although this one is a decoration.
