Varietals are the skins, or styles, applied to Oenology.
Just like the grapes used in winemaking, Oenology varietals take two forms: white and red.
The default varietal is Chardonnay. A versatile varietal for food-wine pairings, and a versatile varietal for Themes, Chardonnay adds just a touch of color and style.
Oenology also comes pre-packaged with a completely blank-slate varietal, Cuvee. This varietal adds a bare-minumum of style, and is well-suited as a template for custom Theme skins via Child Theme.
