Flavor Profile Differences

Rye spice is the dividing line here.

  • Stellum Bourbon: Barrell's lower-priced, cask-strength line. It drinks gentler than its proof, with vanilla and caramel on top of cinnamon, clove and a long, spicy finish.
  • W.L. Weller Full Proof: Weller's wheated bourbon bottled at its barrel-entry proof of 114, without chill filtering. Coffee cake, caramel and cinnamon with a bold, warming body.

Which One Should You Choose?

  • Go with Stellum Bourbon if you want a cask-strength, multi-state blend that drinks easier than its proof at a significantly lower price point and without hunting for it.
  • Go with W.L. Weller Full Proof if you want a bold, sweet wheater bottled at barrel-entry proof.
