Instant yeastFrom the site
🔗For the first time in my life, I really started using instant yeast a couple of weeks ago, after reading from Calvel that, unlike pressed and dry active yeast, this yeast does not give yeast flavor and aroma to products even when using very high amounts of yeast in the dough. ... That is, according to Culvel, emphatically wheat bread is obtained with instant yeast and it is easier for a baker to control the appearance, taste and aroma of products by manipulating the processes of fermentation and baking of dough with such yeast. Long fermentation at low T - a powerful aroma, small amounts of yeast in the dough - a golden (non-combustible) crust even in pastries, etc.
I cannot show in the picture the aroma of bread made from dough fermented for a long time in a cool way. But here's how the amount of yeast in the same recipe affects the color of the crust and its quality. The small loaf on the left has 2p more instant yeast than the loaf on the right. The more yeast, the darker the rind. Regardless of the amount of baking.
Quote from Calvel (2001, The Taste of Bread)
In other words, instant yeast is the freshest yeast, because only fresh yeast has no "yeast" aroma, only the aroma of freshness. The pressed yeast begins to die and smell of (dead) yeast as soon as the pack is unpacked and under imperfect storage conditions and over time it smells more and more of yeast, sweetish and with some bitterness, and the strong yeast aroma of dry active yeast is noticeable as soon as you open the jar, therefore that every dry yeast ball is literally covered in a crust of dead yeast cells. In this sense, instant yeast are considered the most neutral in smell, pressed fresh yeast (at the time of packaging at the factory) in second place, and active dry yeast that smells the most.
Then I found confirmation of this fact that instant yeast is "non-smelling" from Cook's Illustrated. They tested yeast in all of their yeast recipes and taster groups, and actually discovered yeast flavor in the non-flavorful items on pressed or dry active yeast. There was no such aroma with instant. In pastries, the aroma on any yeast was the same, the difference was subtle, and they explain this by the fact that there the aroma and taste of honey, milk, butter, vanillin, etc. interrupt the yeast aroma even from dry active yeast. make it invisible.
Quote (Cook's Illustrated, September 200, Yeast Types)
Instant Yeasts: Also called "Instant," "Rapid Rise," or "Bread" instant yeasts are also processed to 95 percent dry matter, but are subjected to a gentler drying process than active dry. As a result, every dried particle is living, or active. This means the yeast can be mixed directly with recipe ingredients without first being dissolved in water or proofed. It is in this context that the yeast is characterized as "instant." We prefer instant yeast in the test kitchen. It combines the potency of fresh yeast with the convenience of active dry, and it is considered by some to have a cleaner flavor than active dry because it contains no dead cells. (In our months of testing, we found this to be true when we made a lean baguette dough but could detect no difference in flavor when using the two yeasts in doughs made with milk, sugar, and butter.)
Of course, the statement that in instant yeast every cell is alive contradicts an article from the website of King Arthur flour, which claims that dry active yeast contains up to 70% dead yeast, and dry instant yeast - about 30%.

Active dry yeast is live yeast that’s been dried, a process that kills up to 70 percent of the yeast cells. These dead cells surround the live cells, acting as a cocoon to protect them. For this reason, you must “proof” active dry yeast - dissolve it in water, to expose the live cells - before baking with it ....
Instant yeast is also live yeast, but it’s been dried at a much lower temperature, and using a different process. Only about 30 percent of the cells are dead, and therefore it begins to work much faster than active dry yeast
Well, okay, let them break spears between themselves and test the aromas and the number of living cells. I just want to bake bread and it was interesting for me to try instant yeast, its effect on the aroma and appearance of bread. I don't really need to use them, because I can buy fresh pressed in a bakery and dry active ones. They are always available at the grocery store.
I bought instant yeast from the most interesting and famous brands and started baking. How I have suffered! HORROR. The dough behaved as if it had gone crazy. Well, very unusual. I felt uncomfortable and started buying bread for my family in the store! Just in case of fire. What I did with instant yeast, I simply could not be guaranteed to serve it on the table. I was kneading the dough, not knowing in advance what I would get. Unbelievable, but it is a fact.Instant yeast turned out to be more than just dried yeast. This is a different yeast (other strains of baker's yeast). It is just as much different from fresh and dried fresh and dried ones that we are used to (housewives of my generation, let's say), as wild tremors in sourdough or on the surface of fruits differ from store-bought ones in a pack (wild ones are 200-300 times weaker than store-bought ones). They (for the most part) are designed for recipes created in the West AFTER 1970. Only one sort of instant yeast proved to be suitable for baking according to GOST recipes and technologies and according to any other recipes with the traditional process of fermenting the dough (sponge or non-steam with fermentation for more than 1 hour).
Fleishmann's RapidRise Yeast (QuickRise in Canada), that is, fast yeast (rapidly activated and rapidly dying in the dough) turned out to be unsuitable even for a relatively fast, unpaired dough with a fermentation of only 2 hours, with one stirring. This yeast is designed to ferment for 10-20 minutes, as in the Khrushchev dough. That is, this dough is practically no-time dough, like soda dough! Quick yeast dough knead, intensively develop gluten in it by kneading? and after 10-20 minutes of rest, the blanks are formed and put on proofing, baked. Fast instant yeast CANNOT (according to the company website) be soaked in water (I have tried it, and in fact I CANNOT), it then ceases to be "fast". They must be mixed with flour and other dry ingredients and filled with hot (55C) water.
I tried to knead the dough on fast instant ones in the traditional, unpaired way: I soaked the yeast in warm water, kneaded the dough, fermented it for 2.5 hours with one kneading and then molded, 1 hour proofing and baking. The dough was inhibited right before our eyes. Instead of a normal process - more and more rapid swelling after each kneading, it behaved the other way around: it grew more and more slowly and less and less and the loaf turned out to be 20% lower than usual, even with three times compared to the usual amount of yeast. In short, they should be used for their intended purpose, as indicated on the jar! For quick patties and buns.
Fleischmann's instant yeast for bread makers is also designed for a very short-term fermentation of unpaired dough, about 1 hour.
The scent of the yeast of this company turned out to be the strongest smell in dry active yeast, a weak yeast smell in instant yeast (fast and instant for bakeries) and a complete absence of smell, pure aroma of freshness from a jar, in instant yeast for pizza.
I also tried baking with instant yeast, not for busy housewives, working modern mothers and wives, who have only 10 minutes of time for bread and pies dough, but for professional bakers who have time in bulk and who can ferment the dough even for days if they so you want to develop the aroma and taste of the bread. For this purpose, I purchased SAF yeast, known in Russia for SAF-moment fast-acting yeast for home baking and SAF for muffins, similar to Fleischmann's fast yeast, which I described above. Here SAF is better known for baking instant yeast SAF-red pack and SAF-gold pack (SAF-Red, SAF-Gold). If anyone is interested if someone is from Toronto like me, then you can buy them here. In the same store, you can buy bakery ammonium if someone bakes confectionery products in accordance with GOST.
Instant yeast in a red pack is intended for quick types of dough - from 10 to 60 minutes of fermentation after kneading the dough. They recover quickly when soaked in warm water or when mixed directly with flour. A new, even more powerful strain of instant yeast, it is called the new generation yeast - SAF instant Premium, sold in an even more red pack. This yeast produces 30% more gas, which allows you to either ferment the dough faster and ferment the products faster, or reduce the amount of yeast in the recipe by 30% (and thus the products will be better stored, less stale). Products with this yeast grow very high in the oven (huge oven spring).
For all other types of dough (and not just for muffins) yeast in a "golden" pack is intended. So if you knead the dough for a non-steam dough according to GOST, which is fermented for up to 5 hours, and even more so for sponge dough, you need to use this particular yeast. They are great. They perfectly raise both rich and non-dough dough, both salty and unleavened, both steep and liquid, both fast safe and slow sponge. They don't die halfway. The dough continues to grow briskly, no matter how much you crush it.

I am probably the very last housewife in the world to try instant yeast baked goods for the first time 45 years after they went on sale. This is a very interesting yeast, it really doesn't smell and has great lift, but it is specialized. They must be handled as indicated on the package or manufacturer's website. I probably won't buy instant ones for housewives, simply because they are expensive (in terms of a gram of yeast) and I rarely bake from quick yeast dough, like Khrushchev's. But the "golden" SAF's won my heart. I want to bake with them! The most delicious challah in my life is made on them, including challah according to the recipe of GOST 1938-88. The purest, wheaty aroma and taste of bread. Well, just generally.
A comparative table for "lifting force" (how much the dough swells in 2 hours, how much gas one or another yeast emit) allows you to determine when using yeast. Instant yeast will either raise the dough faster than pressed yeast, or you need to take a smaller amount so that the dough fermentation takes as long as the pressed yeast dough!

According to the baker's bulletin from Lallemand, a major producer of instant yeast (in particular, the Fermipan brand), instant yeast can be mixed directly with flour when kneading the dough at a slow speed, i.e. if yeast is mixed directly with flour, then the dough must be allowed to swell, then slowly and knead it thoroughly - by hand or in a mixer, preferably with autolysis, so that the yeast is properly soaked inside the dough and distributed inside. However, the maximum activity of instant yeast (and, thus, the smallest amount of them in the dough is required) is achieved precisely when they are soaked for 10 minutes either in warm (40C) water, or in a warm liquid flour mash (1 part flour + 5 parts water, 40C). Pre-soaking the yeast allows it to be used in dough without autolysis and when kneading the dough in a combine (with knives). When soaking instant gold, I got a wonderful, lush bread according to GOST and according to American recipes, designed for 2-4 tbsp. l. (20-40 g) dry yeast, even 0.5 g (1/8 h. l.) instant yeast per 1 kg of flour in the dough! Here is such
For me, with my so far little experience of using instant yeast, the correct method of storing them remains a mystery. Opinions differ greatly on this matter. Even manufacturers on their websites disagree on opinions and recommendations. It is clear that there are people who have stored instant yeast for 10 years at room temperature (or in the cold) and still fermenting dough with yeast from a pack of ten years ago with good results. On the other hand, it is also understandable that manufacturers advise professional bakers to store the yeast for only three days after opening the package. Instant yeast is very porous and reacts instantly with oxygen in the air.
In a textbook for Canadian bakers, the authors write that three days is too conservative an estimate. Bakers often store open instant yeast in the refrigerator (in a sealed container) for weeks or months without doing anything.Scientific studies of the stability of Fermipan yeast have shown that when storing the yeast closed after opening the pack, at T 3C (in an ordinary refrigerator), opening the pack 3 times a week, the activity of dry Fermipan yeast (the amount of gas they emit) decreases by about 8% for 4 months. That is, instead of 2g of yeast in the recipe, you would have to use 2.18g or lengthen the fermentation and proofing period for a few minutes to get bread of the same quality and splendor. When storing an open pack at 25C, it was necessary to lengthen the proofing by almost 2 times, from 30 minutes to 50 minutes, in order to get bread of the same splendor.
But for us, for home bakers ... Where is the golden mean? Where to store them after we have opened a large pack, which will last for almost a year? The advice of manufacturers and authors of books falls into 2 categories: (1) store in the freezer for up to several months, hermetically packed, so Beranbaum advises Rosa Levi (2) to store in the coldest place (0-4C) in the refrigerator, hermetically packed (from several weeks up to several months, depending on the brand and yeast strain).
I put half in the refrigerator and half in the freezer. Let's see how they behave over time in the same recipe, compared to yeast from a freshly opened pack. Proponents of non-freezing instant tremors (for example, Maggi Glaser) mainly argue that water crystals in yeast rupture cells when frozen. Although there is so little of this water in instant yeast, only 3% (compared to 70-75% of water in compressed yeast, which is often frozen), it shouldn't even be said about it, but all the same: on the Russian site of the Pakmaya brand yeast, SAF-Nevada and "Voronezh" is written in black and white - you can not freeze. By the way, it also indicates that the lifting force of the Voronezh and SAF Nevada is 2p more than that of Pakmaya (30 minutes and 60 minutes, respectively). And the sellers of the latest red version of SAF instant yeast nevertheless guarantee that the instant yeast will not do anything even after 5 years of storage in the freezer. ...
I wonder what kind of yeast do you use, in particular which instant yeast, in what quantities per kg of flour, and how do you store it?
