Asahi Breweries is set to launch a new beer called "Asahi Super Yeast Draft Beer", which contains a special type of yeast that undergoes a second-stage of fermentation, after the beer has been bottled.

The beer is bottled just prior to distribution, and continues to ferment, changing its smell and taste for as long as two to three months. Information from Asahi says that the tastes shifts from a noticeably enhanced taste after one month, and progressing to an abundant and smooth flavor with crisp aftertaste after two to three months.

Asahi will begin rolling out the new beer on November 30 in parts of Japan. No word on when it will hit the States.
