How do winemaking techniques impact the taste of Syrah wines?

Winemakers have numerous methods of influencing the character of Syrah wines. Aromas of vanilla, spice, and toast are obtained from oak aging, whereas the fermentation temperature influences the color extraction and tannin development. Maceration age, a period in which skin contact occurs during fermentation, affects the body, tannin character, and aromatic expression of the wine bringing winemakers opportunities to create wines of different styles and profiles.
