If the water feels warm, it will be around 100 degrees F. To find out if water is cold, look for condensation on the container it's in as this will show it's colder than the surrounding air. Yeast reactivates best between 110°F and 130°F (43°C and 54°C). The ideal temperature is 105 to 110 degrees Fahrenheit. An important thing to note, however, is that if you choose to use lukewarm water with instant yeast, you need to decrease the total liquid in the recipe by 1/2 cup to account for the water you added with the yeast.
But others report lukewarm water falls between 98 and 105 F. However, there are schools of thought that lukewarm means room temperature (72 to 74 F), and others believe it means body temperature (98.6 F), while one definition is adding 15 degrees to room temperature If you feel comfortable choosing one of these temperature ranges, use a thermometer to determine when the liquid is lukewarm.

The more impurities the water has, the higher the temperature will need to be before the water will boil.Never stick a finger or hand in water that is boiling or near boiling. At some point, you may find that you need to determine the approximate temperature of water and do not have a waterproof thermometer. Keep in mind that yeast can die due to other factors rather than temperature. If you want to form a very rough idea of whether water is cold, lukewarm, or hot, first hold your hand above the water. The enzymes are exhibited at this temperature. Water at 81° to 100°F is the optimum temperature range for the fermentation process. Water at 79°F are considered the optimum temperature for achieving yeast multiplication. Run the water over your wrist and if it feels warmer than your body temperature, but not hot, that should be just about right. Every day at wikiHow, we work hard to give you access to instructions and information that will help you live a better life, whether it's keeping you safer, healthier, or improving your well-being.
