What is Chenin Blanc?

Chenin Blanc originated in France's Anjou region. The varietal embodies a unique blend of history and versatility in the realm of white wine grapes. It is celebrated for its adaptability in producing a wide array of wine styles, appealing to a broad spectrum of wine enthusiasts.

Central to the character of Chenin Blanc is its naturally high acidity. This intrinsic quality lends the wines a crisp and vibrant taste, balancing the complexity of flavors that can range from delicate apple and quince to rich honeyed notes. The grape's uneven ripening is key to this versatility.
