Merlot (/ ˈ m ɜːr l oʊ / MUR-loh) is a dark blue–colored wine grape variety that is used as both a blending grape and for varietal wines. The name Merlot is thought to be a diminutive of merle, the French name for the blackbird, probably a reference to the color of the grape.
The next process in the making of red wine is malolactic conversion, a bacterial process which converts "crisp, green apple" malic acid to "soft, creamy" lactic acid, softening the taste of the wine. Red wine is characteristically transferred to white oak barrels to mature for a period of weeks or months; this practice imparts oak aromas and ...
The biochemical process of fermentation itself creates a lot of residual heat which can take the must out of the ideal temperature range for the wine. Typically, white wine is fermented between 18–20 °C (64–68 °F) though a wine maker may choose to use a higher temperature to bring out some of the complexity of the wine.
The wine can then be siphoned or "racked" off the compact solids into a new container. [3] But this process may take many months, or even years, as well as several rackings, in order to produce a perfectly clear wine. Producers can accelerate the process by using fining agents, filtration and/or flotation. [1]
The harvesting of wine grapes is one of the most crucial steps in the process of wine-making. The time of harvest is determined primarily by the ripeness of the grape as measured by sugar , acid and tannin levels with winemakers basing their decision to pick based on the style of wine they wish to produce.
Increasing the amount of second-wine can be a very conscious decision on the part of a winemaker, as a way of making a more and more superior grand vin - able to compete with the most prestigious wines in tastings. [20] After blending, the wine will be bottled, and will then usually undergo a further ageing process before being released.
To macerate is to soften by soaking, and maceration is the process by which the red wine receives its red color, since raw grape juice (with the exceptions of teinturiers) is clear-grayish in color. In the production of white wines, maceration is either avoided or allowed only in very limited manner in the form of a short amount of skin contact ...
Solera is a process for aging liquids such as wine, beer, vinegar, and brandy, by fractional blending in such a way that the finished product is a mixture of ages, with the average age gradually increasing as the process continues over many years.
