It can also mean blending a red wine with a white wine in order to make a rosé. Cutting may also refer to the illegal practice of diluting a wine with water. The French term tailles or "cut" refers to the point during pressing when the quality of the grape juices degrades. The first tailles is the free-run juice followed by successive pressing ...
Temperature swings (such as repeated transferring a wine from a warm room to a cool refrigerator) can also cause adverse chemical reactions in the wine that may lead to a variety of wine faults. In general, a wine has a greater potential to develop complexity and a more aromatic bouquet if it is allowed to age slowly in a relatively cool ...
A refrigerator maintains a temperature a few degrees above the freezing point of water. The optimal temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F). [3] A freezer is a specialized refrigerator, or portion of a refrigerator, that maintains its contents’ temperature below the freezing point of water. [4]
Large pectin molecules can affect the amount of juice yielded at pressing, ease of filtration and clarification, and extraction of tannins. Grapes contain natural pectolytic enzymes responsible for softening the grape berries during ripening, but these are not active under wine-making conditions (due to pH level, SO 2, and alcohol.) Therefore ...
Semi-sparkling is a wine with 1 to 2.5 additional bars (15 to 36 psi) of pressure. Semi-sparkling wines include wines labelled as Frizzante, Spritzig, Pétillant and Pearl. Sparkling is a wine with above 3 additional bars (44 psi) of pressure. This is the only wine that can be labelled as sparkling under EU law.
A pot-in-pot refrigerator, clay pot cooler [1] or zeer (Arabic: زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed.
This will dramatically swell the berries, potentially causing to them crack or burst which will make the prone to various grape diseases. Even if the berries do not crack or burst, the rapid swelling of water will cause a reduce concentration in sugars and phenolic compounds in the grape producing wines with diluted flavors and aromas.

In the cooling step on the inside of the refrigerator, the g state particle absorbs energy from ambient particles, cooling them, and itself jumping to the e state. In the second step, on the outside of the refrigerator where the particles are also at an e state, the particle falls to the g state, releasing energy and heating the outside particles.
