Chenin Blanc wine is made from special white wine grapes. These grapes are grown in vineyards all over South America and are the most popular choice for a wine grape.

Anjou Blanc is a wine from the loire valley- The grape used is chenin blanc. This wine can have a hint of sweetness with a clean crisp mineral finish. Drink up!

Chablis

Champagne

Chardonnay

Chenin blanc

It is unlikely that either of the wines has any intrinsic value, in other words they are probably undrinkable. Although chenin blanc ages well I suspect this doesn't apply to chenin rose (which must have red variety in it as well.There may be some sort of interest as historical artifacts.

If you own these I suggest you get a couple of wine loving friends around and drink the wine. have a couple of more recent wines on hand in the event (very likely) that you are disappointed. They may be quite interesting, but I doubt if anyone would pay any serious money for them.

Cheers

it is blanc de blanc
