How many grams of sugar per litre contains a must at 21° Brix?
To determine how many grams of sugar per litre contains a must at 21° Brix, we can refer to the definition of the Brix scale. The Brix scale measures the sugar content of an aqueous solution, where 1 degree Brix is equivalent to 1 gram of sucrose in 100 milliliters of solution. Therefore, a must at 21° Brix contains 21 grams of sugar per 100 milliliters.
We need to convert this to liters, so we multiply by 10 (since there are 1000 milliliters in a liter). This gives us:
21 grams/100 mL x 10 = 210 grams of sugar per liter.
So, the correct answer to the question is B. 210 grams.
What is the role of Oenococcus Oenis in the winemaking process?
Oenococcus oeni is a lactic acid bacterium (LAB) that plays a crucial role in the winemaking process, particularly during malolactic fermentation (MLF).
Oenococcus oeni plays an essential role in transforming the acidity, flavor, and stability of wine, particularly in the context of malolactic fermentation
What are the characteristics of a good cork? State at least four of them.
-Elasticity and Flexibility
A good cork should be flexible and elastic, allowing it to fit tightly into the bottle neck.
-Tight Seal (Impermeability)
The cork should form a tight, impermeable seal between the bottle and the external environment, preventing oxygen from entering while keeping the wine inside intact.
-Consistency and Quality of Material
A high-quality cork is made from virgin cork (i.e., not recycled cork), typically from the cork oak tree (Quercus suber).
-No Off-Flavors or Taint (Cork Taint-Free)
A good cork should be free from cork taint, which is caused by the presence of trichloroanisole (TCA), a compound that can give the wine musty or moldy odors.

What is this?
Sexual confusion, which has been practiced in French vineyards since 1996, is a natural method of combatting grape worms.
The pheromone is contained in plastic capsules which are hung on the supporting wires in the vineyard (500 per hectare) just before the butterflies arrive in spring each year. The male butterflies can’t locate the females which means less mating and fewer eggs which results in fewer caterpillars and less damage to the grapes.
Who is the owner/winemaker of Domaine d’Auvenay?
