Marker's Mark has introduced a new, even smoother version of its old standard, bourbon whisky Marker's 46 ($40). Removed from the barrel like the standard Marker's Mark at full maturity. But while it's removed, 10 seared French oak staves are attached to the inside of the barrel, then the Marker's goes back in to begin the months long process of becoming 46, a process which adds natural caramel, vanilla, and spice flavors without adding any bitterness.
Only 25,000 cases will be shipped this year, so if your wanting to give it a try and see it in the local liquor store, don't hesitate.
