Chardonnay white wine in Chablis has become a name of origin (AOC) of France, as well as Sancerre with white sauvignon blanc in the valley of the Loire River. But chardonnay makes Chablis unlike chardonnay commonly found in wine regions of the New World, even in some parts of France such as Bourgogne, valley of the Loire River, Languedoc ... According to Mr. Jean-Bernard Baudron, wine expert The French are working in the chain of The Warehouse, chardonnay grapes which are suitable on the limestone lands, but in Chablis in the Bourgogne region, which is considered the home of this grape (Yonne province to be exact). found in the limestone bed there are many fossil oyster shells, suggesting that this area was once a sea. It is this characteristic that helps Chablis wine to have distinct mineral characteristics, a little sour taste and freshness, it can be said that it is closer to the taste properties of sauvignon blanc than chardonnay, which is usually fatty, plump and aromatic. the smell of ripe fruit.

White wines are generally new wines, except for sweet wines. But with chardonnay, some products can last for many years if they are made from vines older than 30 or 50 years old. Meanwhile, the wine has a higher complexity, fullness and fruity aroma, with a long lasting finish. Chablis white wine is rated for quality from Petit Chablis to Chablis, Premier Cru and Grand Cru (this premium type accounts for about 3% of Chablis annual output). If the Grand Cru class has only seven vineyards (about 100 hectares) and the respective recognized brand (including Bougros, Les Preuses, Vaudésir, Grenouilles, Valmur, Les Clos and Blanchot), Premier Cru brings together about 40. name. The qualitative difference between these two classes, in addition to the impact of the location of the vineyard and the subregional climate, lies in the perennial potential and complexity of the taste. In addition to the manufacturer's winemaking style and the year of harvest that has a definite impact on quality, Grand Cru Chablis can last for more than 15 years, while some Premier Cru bottles can last 10 years.

Mr. Baudron said that in Napa Valley, California (USA), at times some wineries even named Chablis for bottles of chardonnay sold on the market, showing how attractive Chablis is. On the Vietnamese market, there are a few names Chablis Grand Cru such as Bourgos (William Fèvre, distributor Vinifera), Blanchot (Laroche wine furnace, Red Apron distributor) ... or Premier Cru like Vaillons (William Fèvre) ... The price also reflects the quality ratings that have been defaulted by professionals: Grand Cru is priced at around 3 million VND / bottle depending on the brand, more than double the price of Prermier Cru, while the bottles Petit Chablis or Chablis at the price of 600,000-800,000 VND. However, these bottles represent more of Chablis's purity, mineral taste and freshness.

The quality potency of chardonnay grapes is generally high, making white wines moderately sour, sparkling or even sweet. The sugar content of chardonnay grapes can reach a high level if a sour-sweet balance is maintained, allowing for bottles of wine with strong and varied aromas: from fresh fruits (bananas, pears, mangoes). to dried fruit (chestnut), citrus to spices, and also floral, honey or avocado scents.
