Active dry yeast is granulated yeast that needs to be dissolved in warm liquid before mixing into dough. One metric cup (250 ml) of active dry yeast weighs around 150 grams or 5.29 ounces. Most recipes call for it by the teaspoon, where one teaspoon weighs about 3 grams; a 7 g sachet covers a single loaf of bread.

Small differences in yeast quantity change how fast a dough rises and how it tastes when baked. Weighing in grams takes the guesswork out of measuring this tiny but powerful ingredient.

Instant yeast is milled finer and dissolves straight into dry ingredients, while active dry yeast needs to be rehydrated in warm liquid first. Swap one for the other 1:1 by weight, and expect a similar rise as long as you adjust the method to match. See our Instant Yeast converter.
