Wine Making

What is Wine? A Chemical Journey from Vine to Glass

Wine /wīn/ - defined: 


an alcoholic beverage made from fermented grape juice. 

Wine, often perceived as a simple, elegant beverage, is a result of complex chemical interactions and meticulous craftsmanship. At Triangle Wine Company, we unravel the science behind wine-making and the basic chemistry that transforms humble grapes into an exquisite glass of wine.

The Chemistry Behind Grapes: Grapes are the cornerstone of wine and house sugars, acids, and phenolic compounds, which play pivotal roles in wine production. The primary sugar in grapes, glucose, and fructose, are the fuel for fermentation, while acids like tartaric and malic contribute to wine's acidity, a key aspect of its taste profile.

How Wine is Made:

How Wine is Made

  1. Fermentation:
    • The heart of wine-making lies in fermentation, a process where yeasts convert sugars present in grapes into alcohol and carbon dioxide. This transformation occurs in anaerobic conditions and also results in the creation of heat and other byproducts like glycerol which contribute to wine’s body and mouthfeel.
  2. Malolactic Fermentation (MLF):
    • Post the primary fermentation, some wines undergo a secondary fermentation called malolactic fermentation. In MLF, bacteria convert the sharper malic acid into softer lactic acid, refining the wine’s taste and texture.

Wine Maturation and Aging:

  1. Maturation:
    • After fermentation, wines are allowed to mature to develop their flavors and aromas. This process can occur in stainless steel tanks, glass, or wooden barrels, each imparting different characteristics to the wine.
  2. Aging:
    • Wine aging, either in barrels or bottles, allows the wine to interact with oxygen slowly, evolving its flavor and aroma profile. Moreover, the interaction between wine and a wooden barrel can introduce additional complexities.

Unveiling Varietals: The Influence of Grape Types Different grape varietals bring distinct chemical compositions to the winemaking process, influencing the final character of the wine. For instance, red wine owes its color to the anthocyanins in grape skins, while the tannic content affects its texture and aging potential.

The journey from vine to glass is a fascinating blend of chemistry and craft. Every step, from the fermentation process to maturation and aging, is an orchestrated effort to balance the chemical interactions and unlock the wine's full potential. As you sip on a meticulously crafted glass of wine from Triangle Wine Company, you're not just enjoying a beverage, but partaking in a legacy of scientific exploration and artisanal devotion.
