Although not common worldwide, wine barrels are often used when whisky is made in close proximity to large wine regions – ie Australia.
Usually made from French oak, each style of wine leaves its own character in the barrel for the whisky to use. Heavier red wines can be spicier and full-bodied while lighter wines tend to be fruitier. While white wine can bring out a buttery texture and grassy flavours. Definitely something we’d like to see distilleries experiment with more.
