How wine is made: juice, skins and cellar choices
Learn how grape colour, skin contact, fermentation and maturation shape broad wine styles, without needing to taste or buy alcohol.
The short answer
Why can the same fruit family produce very different wines?
Grape variety matters, but winemaking choices also change the result. Skin contact can extract colour and tannin, fermentation converts grape sugars, and maturation can alter texture and aroma.

Separate colour from structure
Colour, tannin, acidity, sweetness and body describe different attributes.
Read style terms carefully
Still, sparkling and fortified identify broad types; dry and sweet describe another axis.
