"Share of Angels"
Whiskey liquor sleeping in the Yamazaki distillery's storage depot evaporates little by little from the grain of the barrel in a long time. If it comes to a barrel with a long maturation period, more than half will evaporate. However, along with that, sake goes on aging, becoming a whiskey with a deep flavor.
The predecessors thought that "Because we are drinking it with angels, we thought that we were able to get a delicious whiskey" and called the whiskey reduced from the barrel "Angels' share" I got it.
The sake brewers of the Yamazaki distillery also aged over a long, long time in a cradle called a barrel while gently watching over the angels living in the reservoir.
