To craft The Balvenie DoubleWood 17 year old single malt whisky Malt Master David C. Stewart MBE returned to one of his most celebrated achievements – consecutive maturation in two different types of cask, a process often referred to as ‘cask finishing’.

This technique is at the heart of The Balvenie DoubleWood – it sees the whisky matured first in American oak barrels, which impart soft sweet vanilla notes, before being transferred to European oak sherry casks, where the second cask ageing adds rich spicy flavours and a depth and fullness of flavour.

From THE BALVENIE DOUBLEWOOD AGED 17 YEARS -THE BALVENIE official site

My impression was ... look at the chart above. I had already drunk vintage c 18 Years first. And this time I drank this current 17 Years DOUBLE WOOD. Before having this, I thought this current might be the condition of being merely satisfactory because vintage BALVENIE 18 Years was so great. But after having this, the current BALVENIE is also charming and brilliant. Its also has various attractive flavor.
