According to the bevnet, 

Continuing to push the limits of whiskey production, Distillery 291’s newest 291 E Batch #7, “Experimental Whiskey,” is now available for purchase at the Colorado Springs tasting room (1647 S Tejon St, Colorado Springs, CO), as well as a very limited release within the Colorado market. This release, a wheat whiskey aged in used 291 Rye barrels and finished with the distillery’s signature aspen staves, delivers notes of butterscotch, cream soda, and apricot.

“With our E series, we have a little fun, think outside the box, and push our limits,” CEO and Founding Distiller Michael Myers said. “The ‘E’ stands for ‘experimental,’ and that’s exactly what we do with each new entry into this series. Each batch is released at barrel proof, unique from anything else we make.”
