What’s The Difference Between A Whiskey Barrel And A Wine Barrel?

Toasting Oak BarrelsI was shopping the other day and found some oak chips, made from Jack Daniels Whiskey Barrels. They were being sold as flavor enhancers for barbecues. Could I use these to age my wine? Would they have to be toasted first, or would the fact that they had been used for whiskey aging offset that requirement?

Hello Don,

It is important to know that there are some differences between a whiskey barrel and a wine barrel. Whiskey barrels are process differently that wine barrels. The critical difference being that whiskey barrels are charred on the inside, whereas wine barrels are toasted. Doesn’t sound like much of a difference – I know – but the effects on the flavor are very different.

The reason a whiskey barrel is charred is so that the inside of the barrel staves turn into a charcoal. This charcoal’s purpose is to help take out the harshness of a raw whiskey. In a loose sense, the char acts in the same way a carbon filter works on water. It helps to remove the impurities. This char is also what adds the amber color to the whiskey.

Wine barrels are toasted. The reason they are toasted is so that when the wine is aged in the barrel, flavor is added, not taken out. Shop Wine BarrelsWhen the oak staves are toasted at the correct temperature for the right amount of time, various phenols, sugars and other compounds rise to the surface of the wood to interact with the wine while it ages. Flavors ranging from vanilla, to coconut, to caramel can be coaxed from the wood and into the wine by the degree of toasting the oak wood goes under.

Tannins from the wood also react with the tannins is the wine so as to precipitate them out of the wine as a sediment. This helps to mellow the wine, make it more stable and more clear.

There are some other differences between a whiskey barrel and a wine barrel that are not as critical, but we’ll save them for another time.

Don, going back to your question, you could use these whiskey barrel pieces in your wine, but the effects will be vary different from using actual toasted oak chips that are prepared specifically to be used in a wine.

One thing I would urge you to do is make a serious effort to sanitize these oak barrel pieces. There is no reason to assume they were stored in sanitary conditions if they are to be used for smoking.

I would find a container that could be sealed air-tight and kept full of the sulfite solution, so as to keep the floating pieces of wood submerged by the lid. I would use 2 teaspoons of sodium metabisulfite and 1/2 teaspoon of either citric acid or acid blend to every gallon of water. Let the wood soak for several days. The longer the better.

In short, I see not reason why you couldn’t play around with this wood. Just remember that there are differences between a whiskey barrel and a wine barrel that will result in a very different out come in your wine.

  1. Years ago I made 25 gal of wild grape wine and 25 gal wild black berry wine and put them mixed together into a freshly drained whiskey barrel. It was the best wine I and my friends ever tasted.

  2. Here I would like to suggest whisky better than wine barrel especially whisky is so special when it’s producing by using oak barrels. wine a very bad flavor when it’s for Barrel. Try Cask88 for variety of whisky casks collections from leading distilleries and their most popular regions.

  3. Good day I made a test I put a few gallons of wine in a small brandy barrel for a short period of time and I ended up throwing it away it was not drinkable so I would stick with wine barrels or wine chips thank you Norm
