When we began our wood experiments, we wanted to enhance our rye whiskey with the natural wood flavors Brazilian Amburana Oak imparts. We take rye whiskey that is at least 7 years old and add custom toasted Amburana Oak Staves for the last few weeks of aging to impart natural wood flavors of gingerbread, spice and warm notes that play off of the underlying spice of the base Rye whiskey.
