The mellowness of this wine is due to Botrytis cinerea, a fungus that attacks the grape cluster when it is ripe. This is called "noble rot". This fungus pumps water from the grapes, resulting in a high concentration of sugar in the grape cluster.

The harvest, called "late harvest" takes place in October. Passes, known as selections, are done several times by hand, to keep only the ripest grape clusters. The final quality of the product depends on this.

Monbazillac is a wine whith a Protected Designation of Origin PDO (in french AOC) — its production is subject to several rules that guarantee its quality. This AOC has been recognized since 1936 but, for a long time, it suffered from an outdated image for two reasons: its wine-making process has been done with added sugar for a long time, which made it too sweet, and its consumption, which amounted to "an afternoon snack syrup".

Monbazillac is made from a blend of three grape varieties:

- Sauvignon: a very aromatic nose, floral, strong flavour, musky. It is the origin of dry whites. - Semillon: a very sweet grape, good producer of alcoholic content. Its thin skin "takes" the "noble rot" well. It gives fat to the wine.
- Muscadelle: a minority variety with a musky, subtle, delicate nose. It is a fragile grape variety, which gives this natural wine a royal colour.

Monbazillac is a very smooth wine with a musky bouquet, behind which we discover a taste of honey and candied fruit, highlighted by a slight acidity. Depending on the vintage, in our Monbazillac there are very distinct tastes of lychee, apple, mango, and banana or vanilla flavours.

Château La Maroutie enjoys "rare” good luck — it is on soil composed of both clay and limestone, giving the wine an exceptional smoothness and subtlety. Clay soils favour Monbazillac’s creaminess (smoothness), and limestone soils accentuate its delicacy.

Monbazillac is a special wine, it is not a "thirst wine," it owes nothing to necessity, it is refined and sumptuous, it makes an exceptional moment even more sublime.

The favourite wine of the Sun King, they say. But which image, of the king or the wine, was the easiest to capture? The wine. Louis XIV would have found in Monbazillac a perfect symbol of his likeness, recognizing in this wine the strength of the sun, which gives life to everything. Like the "Sun" wine, he comes from the earth (the Kingdom of France, to which he was born as King), the people (his family gave him the throne) and heaven (his power by divine right).
