To celebrate World Whisky Day this year, we asked our Facebook followers to guess how many litres of alcohol went into the 100th GlenWyvis cask, which Duncan filled the previous day. We had many entries, but congratulations go to winner Robert Marshall of Dufftown, whose guess of 130.2 litres was the closest. The exact answer was 130.75 litres of alcohol. We hope Robert enjoys his prize – a bottle of Highland Inspiration Single Malt Whisky.
