Fermentation versus distillation

Fermentation builds the base

Yeast converts fermentable sugars into ethanol and carbon dioxide. Beer production typically begins with malted grain, mashing and a hopped wort; wine begins with fermentable fruit juice.

• Agricultural feedstock shapes available sugars.
• Yeast strain and temperature affect aroma compounds.
• Fermented beverages retain more of the original matrix.

Distillation concentrates and separates

Distillation follows fermentation. Heat and controlled condensation separate volatile compounds, raising alcohol concentration and changing the congener profile.

• Pot and column systems create different separation patterns.
• Vodka targets high rectification; flavour-led spirits retain selected congeners.
• ABV alone does not describe flavour or quality.

Why the boundary matters

The distinction supports useful catalog filters, but products such as ready-to-drink coolers can combine fermented or distilled inputs. The atlas labels process classes as technical categories, not legal definitions.
