Suntory Yamazaki Puncheon Cask Japanese Single Malt Whisky

The 2013 Yamazaki Puncheon release, matured in a puncheon barrel which is much larger than a hogshead cask which only hold 230 litres. A puncheon can hold 480 litres! Being so much bigger the whisky matures a lot slower due to less contact with the wood.
