On certain wines, such as our Petit Verdot, we make note of aging the wine in “tightly grained” oak barrels, which may raise the question: why does oak grain matter? Let us explain…
The notion of tightly grained wood is fairly self evident. Most woods, including oak, come in different grains, depending on the species and where they are grown. Some are more widely grained, others are more tightly packed.
Now, in the wine aging process, wide-grained oak tends to produce a wine that has a more pronounced oak and wood tannin character. In other words, if you want your wine to taste more oaky, or if you have a powerful wine that needs a more assertive oak balance, you might veer toward wide-grained oak.
On the flipside, tight-grained wood is more restrained in its influence. So if you want the oak character of the wine to be more subtle, then you will choose tight-grained oak for aging.
One example is our aforementioned Petit Verdot. In the words of Winemaker Stewart Cameron, “Petit Verdot has some unique varietal flavor profiles that no other Bordeaux varieties have, and we want to keep those at the forefront of the wine. We don’t want it to taste like French oak, so we choose wood with a tight grain and lighter toasting to produce a wine that is varietally true.”
On a more powerful wine, however, such as our Petite Sirah, Stewart might loosen the reins on the grain to ensure that the oak influence is sufficiently present.
And therein lies the significance of oak grain. Ultimately, it’s just one of many arrows in the winemaker’s quiver for guiding the style of a given wine.
