Fresh compressed yeast has half of the rising power of dry. You can cut the amount in the recipe by half or double it depending on what you have and what the recipe calls for. (Note: Most cookbooks for home use refer to dry yeast for recipes unless otherwise stated in the recipe or Preface)
17.64 teaspoons of dry yeast are available in 50 grams of compressed.
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.

1 teaspoon instant (bread machine) yeast = 1 1/4 teaspoon active dry yeast.1 teaspoon active dry yeast = 3/4 teaspoon instant yeast.1 package instant yeast (2 1/4 teaspoons or 7 grams) = 1 1/4 package active dry yeast (2 4/5 teaspoons or almost 9 grams).Hope this helps!
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.
In 1868, Charles Fleischmann made a compressed, distiller's yeast
Yes, except Lallemand/Danstar does not recommend proofing after rehydration of their yeast because they have optimized their yeast's nutrional reserves.
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.
Dry yeast is inactive and becomes active when wet. It doesn't store indefinitely but it does keep longer that compressed yeast. Compressed cake yeast is already active which is why it's kept refrigerated and must be used within days. Compressed activate in warm water 75 90 degrees. Dry active: sprinkle over warm water add a pinch of sugar and wait 10 min. Quick rise: Does not need to be activated mix right into dough. The rule of thumb method of activating yeast also called proofing yeast is to dissolve the yeast in 1/2 cup of warm water temperature is important can't be too hot or cold and let sit for 10-15 min. It should then look bubbly.
