Ask Wine Wizard

I just bought my first barrel and opted for a paraffin-lined model. Will this work or do I need charred barrels for wine aging?

Q

I have been making wine and other spirits for a long time and have even been known to drink wine before its time. This year I decided to age some of my wine. I ordered oak kegs for this purpose, but am now confused. I had two options when ordering the kegs. I could get charred kegs or paraffin-lined kegs. I know that distilled spirits are aged in charred kegs, so I ordered the paraffin-lined kegs.

Now, every time I read anything about aging in oak there will be something mentioned about toasting the oak. Is this “toasting” just a sophisticated way of saying “use a charred keg for wine as well as for distilled spirits?” Please answer soon. My wine is in carboys right now and I am afraid that if I do not put it away soon I will not have any to age.

Charred, toasted, fired … it’s all pretty much the same. In the wine industry, as well as the distilled beverage industry, heat-treated wooden barrels and kegs are used as storage vessels in which wines and liquors are left for a certain amount of time to age. In the process of making brandy or whiskey, the distillate that comes out of the still is entirely colorless. It is actually the toasted — or charred — aging barrel that imparts a golden brown color to the beverage. Likewise, toasting methods are chosen so that the finished product will benefit from the natural aromatic compounds present in the wood. The insides of barrels to be used for distilled spirits, bourbon especially, are usually exposed to a very hot flame and will be entirely black on the inside, what some folks call a very “high toast” level. Barrels used in winemaking can be ordered from coopers at “low,” “medium” or “high” toast, and sometimes only the heads (the flat ends) of the barrels will be toasted. In your case, I would use the “charred”
