What’s in a barrel?


Jim Beam Bourbon Barrel Head

There are two lids per whiskey barrel.  Each lid , or “head” (whiskey barrel head) is made of white oak slats that are held together by the pressure of the liquid inside the barrel – no glue is used.  The stamped lid is called the “money end.” The stamp is a way for the distiller to keep track of whats in the barrel, when it barreled and where it is stored.

For example, “DSP-KY-230” means “Kentucky distiller permit #230, which is the number assigned to Jim Beam. #44 is Maker’s Mark, #50 is Peerless, #52 is Woodford. All are assigned their number in the order of application — so the lower the number, the older the distillery.

D-160 means it was distilled at 160 proof. ”C04 L03” indicates that it was distilled at the C plant in 2004 (C=place, 04=year) on December 3rd. (A=January, B=February, C=March, etc.)


Custom Barrel head Charred Side

The rules are pretty strict for whiskey that has the honor of becoming bourbon – all that can go in is grain, water, and yeast, and they must be aged in a new white oak barrel.

In order to give whiskey its deep caramel color and rich smokey flavor notes, distilleries lightly “toast” the barrels to caramelize any natural sugar in the wood and then burn the ever living heck out of it for 6-12 seconds to give it a good char.  The barrel heads themselves are often charred longer – for 90 seconds or so.

Naturally, the charred side of your barrel head did its part to make a delicious batch of Kentucky’s liquid gold.


There’s no glue used in the production of whiskey barrel heads – only holes, dowels, and a bit of parafin wax around the outside to help the seal. The entire barrel coopering process is done the same way it always has – entirely by hand.

Solid craftsmanship eliminates the need for adhesive, which could touch the whiskey and interfere with the flavor. The way the wood slats fit together also allow them to expand and contract comfortably as the whiskey ages over the years.


For those who would like a cleanly engraved barrel head for formal events, wedding guest books, or simply because you prefer the look, we offer “planing” or “resurfacing,” which takes off the top layer of the wood so that it becomes flat and bright, perfect for signatures and high contrast.
