At the Yunessun Spa Resort in Hakone, Japan, you can swim in one of 25 specialized pools, including Coffee, Tea, Wine or Sake! Yunessun describes their Red Wine Spa as, "A unique spa containing real red wine. The huge wine bottle is 3.6m tall and is very remarkable. Bathing in wine is a rejuvenation treatment for the body, and it has been said that the Queen of Egypt, Cleopatra loved to bath in wine. There are regular performances of pouring real wine into the spa a few times a day."
We covered German Beer Spas in May, but this is a step up.
