Active dry or instant?
Active dry has larger granules and needs to bloom in 38–43°C water for 5–10 minutes before use. Instant yeast is finer and goes directly into flour. Both weigh ~150g per cup.

Comparison
Dry Yeast vs Other Leaveners
Yeast is biological — fundamentally different from chemical leaveners. Understanding the difference prevents the most common baking substitution mistakes.
| Leavener | g / Cup | Type | Profile | Best For |
|---|---|---|---|---|
| Dry Yeast this page | 150g | Biological | Slow, hours | Bread, pizza, rolls |
| Instant Yeast | ~150g | Biological | Faster, direct mix | Bread machines, quick dough |
| Fresh Yeast | ~240g | Biological | Very active, moist | Bakery-style enriched dough |
| Baking Powder | ~192g | Chemical | Instant, double-acting | Cakes, muffins, biscuits |
| Baking Soda | 220g | Chemical | Instant, needs acid | Cookies, buttermilk batters |
Active Dry vs Instant: Use 25% less instant when replacing active dry. 1 tsp active dry = ¾ tsp instant. Both weigh ~150g per cup. Fresh yeast: replace 7g dry with 17–21g fresh.
Technique
How to Measure Dry Yeast
2
Measure before hydrating
Measure granules dry. Once dissolved in water, the original quantity cannot be verified. For precision, weigh on a digital scale — 7g = one standard packet.
3
Level teaspoons only — never heaped
A heaped teaspoon can be 20–30% more than a level one. For no-knead and long-ferment recipes using 1–3g, a kitchen scale is the only reliable tool.
4
Water temperature is as important as weight
Ideal: 38–43°C (100–110°F). Above 60°C kills yeast instantly. Below 21°C, yeast is dormant. Always bloom active dry yeast if the jar is more than 3 months old.
One Standard Packet
Most practical ref
2¼ tsp
One US packet = 7g = 2¼ tsp. The benchmark for sandwich bread, pizza dough, rolls, and most home bread recipes.
Old or Weak Yeast
Test first
Bloom it
Stale yeast measures correctly by weight but fails to rise. Always run a freshness test before any important bake.
Instant Yeast
No bloom needed
×0.75
25% more active than active dry. Use 25% less when substituting. Mix directly into flour — no water blooming required.
Freshness Test
How to Test If Your Dry Yeast Is Still Active
1
Warm 60ml (1/4 cup) water to 38–43°C — comfortably warm on your wrist.2
Dissolve 1 tsp of sugar in the water to feed the yeast.3
Add 1 tsp (~3g) of dry yeast. Stir gently and leave undisturbed for 5–10 minutes.4
Healthy yeast: foams and doubles in volume. Dead yeast: no foam — replace before baking.Precision
Why Gram Weight Changes Everything
Yeast is not a passive ingredient. It controls fermentation timing as much as rise. A small measuring error shifts the entire bake schedule.
🍞
Too much yeast causes overproofing
Excess yeast makes dough race upward then collapse before baking. The crumb becomes coarse and the loaf can taste overly yeasty or sour.
🍕
Pizza timing shifts with yeast weight
A small difference means dough ready in 2 hours vs 6 hours. Cold-ferment pizza with even 0.5g too much overproofs by morning.
🥐
Sweet doughs stress yeast more
Sugar and fat inhibit yeast activity. Brioche and cinnamon rolls need slightly more yeast — but not so much the dough races past shaping time.
⏰
Long-ferment recipes rely on tiny amounts
No-knead and overnight doughs use just 1g. A full packet in these recipes causes overproofing in hours instead of the full overnight ferment.
The takeaway: Measuring yeast by grams makes bread, pizza, and rolls ferment predictably every bake — especially when scaling recipes up or down. A digital scale solves this completely.

FAQ
Frequently Asked Questions
7 grams = 2¼ teaspoons (2.25 tsp) — exactly one standard US packet. This is the benchmark for sandwich bread, pizza dough, cinnamon rolls, and most home bread recipes.
Active dry has larger granules and needs blooming in 38–43°C water for 5–10 minutes. Instant yeast has finer granules, disperses directly into flour, and acts about 25% faster. Both weigh ~150g per cup. Use 25% less instant when substituting — 1 tsp active dry = ¾ tsp instant.
More yeast rises faster — but faster is not better. Complex bread flavor comes from extended fermentation, during which yeast and bacteria produce organic acids and hundreds of flavor compounds. Many artisan bakers use just 1–2g with long cold ferments (12–24 hrs) to maximize flavor.
Ideal: 38–43°C (100–110°F) — warm bath water on your wrist. Above 60°C (140°F) kills yeast instantly. Below 21°C (70°F) yeast is dormant. A kitchen thermometer is most reliable; without one, let hot tap water cool 30 seconds.
No. Chemical leaveners produce CO2 almost instantly. Yeast is a living organism that ferments slowly over hours. Bread and pizza dough rely on yeast for texture and the subtle tang that no chemical leavener can replicate.
Fresh yeast is ~70% water and far more perishable. Fresh to active dry: use 1/3 the weight (21g fresh = 7g active dry). Fresh to instant: use 1/4 the weight (21g fresh = ~5g instant). Fresh yeast must be refrigerated and used within 2 weeks.
Unopened: 2–4 years at room temperature. Opened jar: store airtight in the refrigerator, use within 4 months. Freezer: up to 6 months airtight. Always run a freshness test before any important bake.
US packets are 7g (1/4 oz) — the most common global standard. UK and European packets may be 6g or 7g. If following a non-US recipe that specifies "1 packet," always check the gram weight on the label.
