The most striking expression of our Tsukuriwake - Diversity in whisky making, is probably the variety of casks used during the maturation process. No less than four types of oak wood (American, Japanese, Spanish, French) are used to impart each whisky with its unique characteristics. #SuntoryTime #HouseofSuntory #SuntoryWhisky #JapaneseWhisky #Whisky #Yamazaki
