I actually did it the easy way. My parents went to this distillery in New York and came back with this starter kit as a gift for me. Rater than using a cask they give you bottle with a charred oak stave in it which has a similar effect. All I had to do was poor the cocktails and wait to weeks.Incredibly smooth, sweet and smoky. Next batch I am going to pull back a little on the vermouth and try waiting longer.
