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 natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
In red musts, this increases color and tannin extraction. [2] After fermentation, the force of gravity may eventually cause the wine to "fall bright" or clarify naturally, as the larger suspended particles gradually settle to the bottom of the storage vessel. The wine can then be siphoned or "racked" off the compact solids into a new container. [3]
Red wine represents 52% of total wine consumption in Spain, [9] 55.6% in Italy in 2004, [12] and 70% in Switzerland. [10] In Canada, red wine dominates with a 52.3% share of total wine sales in 2004, although there are regional disparities, with Quebec favoring it even more. [13] In the United States, there is a balance between white wine ...
