The four elements to activate yeast are warmth, moisture, food, and time. Yeast thrives in warm environments, typically around 100°F (37°C), which helps it to become active. Moisture is essential as it hydrates the yeast cells, while food, usually in the form of sugars, provides the necessary nutrients for fermentation. Finally, allowing time for the yeast to ferment and rise is crucial for achieving the desired texture and flavor in baked goods.

Very hot liquids will kill off the yeast. Only use slightly warm water to activate the yeast.
Might be old or the water is too cold to activate it or too hot and killed it.
Activating yeast involves hydrating it in warm liquid to awaken it from its dormant state, activate its enzymes, and kickstart the fermentation process. This helps the yeast to multiply and produce carbon dioxide, which leavens the dough and gives it a rise.
Adding glucose to activate yeast cells provides a readily available energy source for the yeast to begin fermenting and growing. The glucose is metabolized by the yeast into carbon dioxide and alcohol, allowing the yeast to thrive and carry out its fermentation process. This activation step is crucial for ensuring a successful fermentation process in bread-making or brewing.
To activate yeast in a packet for baking bread, mix it with warm water and a small amount of sugar. Let it sit for about 5-10 minutes until it becomes frothy and bubbly. This indicates that the yeast is active and ready to use in your bread dough.
To properly activate dry yeast for brewing beer, first dissolve the yeast in warm water (around 100-110F) with a small amount of sugar. Let it sit for about 10-15 minutes until it becomes foamy. This indicates that the yeast is active and ready to be added to your beer wort.
Your recipe should indicate where and how to add the yeast, but yeast does not dissolve well in milk (if at all). Yeast forms into large clumps when mixed directly with milk and will take much longer to activate. I made this mistake the first time I tried to substitute milk for water when making bread. The usual way of adding yeast to such a recipe is to fully dissolve the yeast in 1/4 cup of warm water (about 110 degrees Fahrenheit). If the water is not warm enough, it won't activate the yeast and if it's too warm, it can kill the yeast. One of my colleagues proofs the yeast in the usual way (1/4 cup warm water, 1 tsp sugar, 1 tsp yeast), then adds the rest of the yeast to the water, mixes the dry ingredients with the milk for the recipe, then adds the water-yeast mixture to that. He claims that it works perfectly. Of course, if you use 1/4 cup of water to dissolve your yeast, subtract 1/4 cup of milk from the recipe unless otherwise indicated. And also make sure you're using the proper yeast for whatever it is you are baking.
Typically this is because you have used too much yeast or let it sit too long.
Yeast need warm temperatures in order to grow. The perfect temperature for yeast is about 110 degrees F. Yeast will not start to reproduce and rise without warm temperatures to activate it.
To activate active dry yeast for baking, dissolve it in warm water (around 110-115F) with a pinch of sugar. Let it sit for about 5-10 minutes until it becomes frothy and bubbly. This indicates that the yeast is active and ready to use in your recipe.
Yes, hot water can activate yeast and help it to rise. The ideal temperature for yeast activation is around 100-110°F (37-43°C). However, water that is too hot can kill the yeast, so it's important to use a thermometer to check the temperature before adding it to the yeast.
