Last weekend was the first time that Walla Faces was able to open our winery at the incubators to the general public. Winemaking is a complex art that involves many processes and a skillful hand to do well. Our tiny winery has many processes going at once, making it a bustling place to visit. Each step of the winemaking process affects how the wine tastes when it finally gets to your table!
The Walla Faces winery is divided into two big sections: a warmer area for malolactic fermentation and a cooler area for aging.
Malolactic fermentation takes place in the warmer part of the winery. During this process, bacteria convert malic acid, a natural part of freshly pressed grape juice, to lactic acid. Malic acid is very tart, with a taste almost like an under-ripe green apple, whereas lactic acid is almost buttery. Thus, malolactic fermentation helps reduce the sharpness and bitterness of the wine, improves the mouthfeel, and enhances the wine’s flavor.
Of course, during malolactic fermentation an even more crucial process is occurring: the sugar is being converted to alcohol! About 70% of the sugar has already been turned to alcohol by the time malolactic fermentation begins in a fast, frothy process called primary fermentation. During malolactic fermentation, the remaining 30% of the sugar is converted to alcohol.
After the wine has finished fermenting, it is time for it to age. A cooler section of the winery is reserved for the wine aging in the barrel. Immediately after fermentation has completed, the wine usually still tastes “green”. The porous oak allows for controlled oxidation, decreasing the astringency and adding greater complexity of aromas and flavors throughout the aging process. In addition, the tannins are softened and the wine begins to take on the character of the barrel.
Last weekend, for holiday barrel tasting, we opened up one barrel of 2012 Cabernet, which is currently undergoing malolactic fermentation, one barrel of 2010 Cabernet, which is currently aging in the barrel, and our Reserve Cabernet in the bottle. This offered winery visitors the opportunity to see how the wine progressed from
Thank you to everyone who came out and visited the winery last weekend!
