What are the key differences between New World and Old World Sauvignon Blanc wines?

Some examples of New World Sauvignon Blanc wines are those from regions like New Zealand and California, which tend to have powerful fruit profiles, such as passion fruit and some melon, combined with zesty acidity and lively aromatics. In contrast, Old World examples from regions such as France’s Loire Valley or Bordeaux are generally more restrained, with prominent herbaceous notes, minerality, and often a touch of flintiness, all of which are characteristic of their cooler climates and the traditional winemaking practices.
