Wine and good music is surely one of the best partnerships in history, and a company in Japan obviously agrees.
So no, you can't drink the wine from the glasses, but instead they act as speakers, with the wine vat in between them actually being a digital amplifier.
The amplifier has a rated output of 4W x 2ch and an input sensitivity of 3000mV, while the speakers are 32mm in diameter, dome-shaped and full range.
Sadly only available in Japan at the moment, the Mini Clear Sound System is avaiilable for 26,250 yen, which is around £120. Bottom's up!
