The short version
Long oak staves are seasoned outdoors for two or three years, then shaped so their edges fit tightly. A cooper raises them inside metal hoops, softens them with steam or heat, and bends them together. The barrel is toasted over a fire, fitted with its round heads, sanded, and hooped again.

Season the staves outdoors
Long planks of oak called staves are stacked outside and left to weather. The rain and sun draw out harsh compounds that would otherwise make wine bitter.
two or three years
Goes in -
Shape each stave
Every stave is cut to a tapered shape with beveled edges. The fit matters, because the finished barrel is watertight without glue or fixings.
-
Raise them in hoops
The cooper stands the staves upright inside a metal hoop to form a cage with a wide middle and open ends.
-
Steam and bend
Heat or steam softens the lignin in the wood, so the staves can be pulled together at one end with a cable and extra hoops without cracking.
-
Toast over a fire
The inside of the barrel is toasted over a low flame. The heat caramelizes sugars in the wood and sets the flavors the barrel will pass on to wine. A wine barrel is toasted for about 35 minutes.
about 35 minutes
-
Cut and fit the heads
Round heads are cut from boards, then wedged into grooves cut near each end of the staves.
-
Sand and rehoop
Work hoops are knocked off, the outside is sanded, and the final hoops are driven into position.

Worth repeating
- A wall painting in an Egyptian tomb from 2600 BC shows a tub made of staves bound with hoops.
- A whiskey barrel is charred for about 45 seconds on a high fire, while a wine barrel is toasted at low heat for about 35 minutes.
- Pliny the Elder reported that coopering began with the Gauls in Alpine villages.
