Conversion at a glance
| If a recipe wants… | Active dry | Instant | Fresh |
|---|---|---|---|
| 1 packet (7 g active dry) | 7 g (2¼ tsp) | 5.5 g (1¾ tsp) | 17 g |
| 10 g instant | 12.5 g | 10 g | 30 g |
| 20 g fresh | 8 g | 6.5 g | 20 g |
Ratios are the widely used approximations (instant ≈ 0.75 × active dry ≈ 0.33 × fresh by weight). Yeast is forgiving — small differences mostly change how fast the dough rises, not whether it does.
How it works
By weight, instant yeast is the most concentrated, active dry needs about 25% more, and fresh yeast needs roughly three times as much as instant. Teaspoon amounts assume about 3.1 g per teaspoon for the dry yeasts. Fresh yeast is sold by weight, so it's shown in grams only.
FAQ
Can I add instant yeast straight to the flour?
Yes. Instant yeast is designed to be mixed into the dry ingredients — no proofing in water needed.
How big is a packet of yeast?
A standard packet is 7 g (¼ oz), which is about 2¼ teaspoons of active dry or instant yeast.
Does more yeast make bread rise better?
It rises faster, not better. A slower rise with less yeast usually builds more flavour, which is the whole idea behind sourdough.
