Under the snowcapped mountains of Fiordland National Park, freshwater streams empty into the saltwater fiords, creating a unique ecosystem. This is a heavily wooded park, so the water in the streams is stained with tannin, a substance found in plants that makes clean water seem dirty, though it isn't.

Tannin is key in turning animal hides into durable leather.

Tanning Substance

Tannin can make plants taste bitter, deterring herbivores.

Bitter Taste

Tannin-rich plants are often used to create natural dyes.

Natural Dye

Tannin affects the aging potential and mouthfeel of wine.

Wine Characteristic

Red wines typically have more tannin than white wines.

Red vs White

Tannin levels can diminish over time, softening the wine's taste.

Aging Influence

Some tannins can be toxic to animals, affecting their health.

Animal Caution

Tannins serve as a defense mechanism for plants against predators.

Plant Defense

High tannin levels in plants can indicate environmental stress.
