    Logs are debarked and cut lengthwise into bolts, and then split into four quarter bolt sections.

    Making a Stave

    Final cuts are made to create the rough staves. They are inspected for quality before being stacked for seasoning.

    Seasoning

    Our staves are seasoned in climates where the natural elements facilitate changes to oak chemistry.

    Raising

    We raise the barrel by choosing staves that tightly fit together to craft the perfect barrel shape.

    Steam Tunnel

    Raised barrels are sent through the steam tunnel to make them pliable. Temporary hoops are added to curve the staves into a barrel-like shape.

    Toasting

    Customers can opt to toast their barrels prior to charring, which releases desirable aromas and flavors.

    Charring

    Lighter char levels show more fruit esters and spice notes while darker char levels extract more vanilla flavors and color into the spirit.

    Heads & Hoops

    After charring, the top and bottom heads are added along with six steel hoops. The bung hole is drilled.

    Quality Control

    Barrels go through a rigorous inspection process where water and air pressure are added to make sure it is liquid tight.
