Approximately 7 teaspoons of dry yeast are equivalent to 50 grams of compressed yeast.
To convert active dry yeast to instant yeast, you need to use 25% less instant yeast. Therefore, if a recipe calls for 7 grams of active dry yeast, you would use around 5.25 grams of instant yeast. This conversion is due to the differences in moisture content and particle size between the two types of yeast. It's important to note that these measurements are approximate and may require slight adjustments based on the specific brand and batch of yeast being used.
This would be a tricky calculation to make, (and please note these are American measurements.) Compressed yeast comes in 2 oz. cakes, which can be divided equally into 3 parts, with each part equal to one packet of yeast. One packet = 2 1/4 teaspoons. As a rule of thumb, one packet of dry yeast is enough to raise about 4 cups of flour. For anyone interested in working with yeast doughs, Google "yeast conversion" to find a selection of tables that will help you make conversions between dry, compressed, instant and even brewer's yeast.
1 (6-ounce) cube or cake of compressed yeast (also know as fresh yeast) = 1 package of active dry yeast 1 package active dry yeast = about 2 1/4 teaspoons = 1/4 ounceTherefore, 1.5 ounces of compressed yeast = 1/16 of an ounce of active dry yeast or 1/4 of the package of active dry yeast.
1 (.6 oz / 17 g) cube or cake of compressed yeast (also know as fresh yeast) = 1 package (1/4 oz / 7g) of active dry yeast
Instant yeast is another type of dry yeast that was introduced after active dry yeast in the 1970s. It is made using a similar process as active dry yeast, although is dried more quickly. As you can see, this yeast is also milled into finer particles. Because of this, it dissolves faster and activates quickly. But unlike active dry yeast, instant yeast doesn't have to be proofed first; it can be mixed straight into the dry ingredients with the same result. This yeast also gives you two separate rises and it can be used interchangeably with active dry yeast.

You can use active dry yeast as a substitute for instant dry yeast. However, you will need to dissolve it in warm water before adding it to your recipe. Another option is using fresh yeast, but be sure to adjust the quantity as it is not as concentrated as dry yeast.
Yes, except Lallemand/Danstar does not recommend proofing after rehydration of their yeast because they have optimized their yeast's nutrional reserves.
In 1868, Charles Fleischmann made a compressed, distiller's yeast
No, yeast is a living organism (bacteria). If you boil it, you will kill it and it will not transform the sugar into alcohol, making it useless.
When yeast is deprived of oxygen, it will convert glucose into ethanol and carbon dioxide through a process called fermentation.
