I was checking out a recent Glenfiddich offering, the Malt Master's Edition, and having trouble understanding it.
"While many of Glenfiddich's whiskies are ‘finished’ in different casks – which happens over a short period where the liquid picks up the subtle notes and flavors of the cask - this is the first Glenfiddich using a full spirit transfer from one cask into another."
What the the heck does that mean?
"Malt Master Brian Kinsman has a natural affinity for innovation. With this, his first Malt Master’s Edition, he marries different aged whisky in two types of oak cask, the first Glenfiddich to be double matured in two different casks. After maturing in traditional Oak casks for a number of years, our malt master transfers the whisky into Sherry Casks for its final years of maturation."
I still don't get it. What, exactly, are they doing? The last sentence sounds like it's the standard process for sherry finishing. But... "double matured in two different casks" and the term "married" is found. And, "full spirit transfer"?
