The pronunciation guide uses the ARPABET phonetic system—the same system used in speech recognition and text-to-speech applications.

Vowel Examples:
AE1 = cat, bat
EH1 = bed, head
IY1 = see, me
OW1 = go, boat
UW1 = boot, do
Stress Numbers:
0 = no stress (unstressed)
1 = primary stress (loud)
2 = secondary stress (medium)
Example:
AH0 TH IY1 N AH0
= a-THEE-na (Athena)

The stressed syllable (marked with 1) is pronounced louder and clearer than others.

Quick Definition

The sugar in grape must that yeast can convert into alcohol and carbon dioxide.

Detailed Definition
Fermentable sugar is the stored energy from which a wine’s strength and much of its texture begin. Its conversion is both measurable and mysterious: sweetness disappears while heat, fragrance, and spirit emerge. In literary use, the term can symbolize latent language waiting for transformation, a reserve that becomes audible only through pressure and living agents. It turns the grape into a small vessel of potential change.
Example
Example in poetry:
“Fermentable sugar fed the yeast that transformed grape juice into alcohol,” uses the term for sugars available for fermentation; “The fermentable sugar disappeared slowly, leaving heat and fragrance behind”; A poet may treat sugar as the hidden fuel beneath the wine’s transformation; “Each grain of fermentable sugar became a breath of the finished song.”
Additional Notes
Fermentable sugar is measured to estimate potential alcohol, often with Brix, specific gravity, or similar scales. Yeast converts these sugars mainly into ethanol and carbon dioxide, though some may remain as residual sugar. Nutrient levels, temperature, and yeast health influence how completely fermentation proceeds.
