I can't tell you how grateful I am when distilleries respond favorably to my customers' requests for wood for use in their wood rings. Most recently, two companies have been kind enough to send me whiskey barrel staves on customers' behalf: Four Roses, a brand I think needs little introduction; Stranahan's, a craft distillery in Denver, CO, who were so cool as to include a couple shot glasses and stickers when they sent their stave. I have not had the pleasure of trying their whiskey (if I see it, Im buying it) but I can vouch for their oak. Solid, top quality material.
These two join a list of available barrel stave choices that is getting a little silly: Jack Daniel's, Woodford Reserve, Four Roses, Stranahan's, Pappy van Winkle, Old Rip van Winkle, Buffalo Trace, Angel's Envy, Knob Creek, Jim Beam, Maker's Mark, and The Macallan.
