Dead yeast is good yeast?

I am calling bullshit on the first article. Does this make any sense to you? "Brewer's yeast is used to brew homemade wines and beers, while baker's yeast makes bread rise. You can't brew alcohol ...

Can I mix two yeasts to add different flavours when I make beer?

This can work very nicely from my experience, I often use S-04 and US-05. The S-04 gives esters as you suspect and the US-05 gives a higher attenuation and a thinner body. The majority of esters are ...

Can I dry my own yeast to make it relatively shelf stable? How?

How did Monks and farmers do it? Farmers in Norway apparently do it with even less fanfare. http://www.garshol.priv.no/blog/342.html Terje took some wort in a plastic bucket. Then he brought out ...

Will reused yeast change beer taste?

we can get away with re-using yeast, because Mutation isn't instantaneous, it take multiple generations to change a whole batches properties. Also bigger brewers use a "mother culture" to grow more ...

According to info I got from John Palmer for an upcoming article I wrote for BYO magazine, the cleanup happens concurrently with fermentation. Here's the quote..."Yeast have 3 phases in their life ...

My re-hydrated yeast has lost a lot of his foam, is it alive?

No, you don't have a problem. Yeast does not die that fast. You can still use the rehydrated yeast, it will get active back again when you pitch it in your wort. If you did not cover it, then just ...

Starsan in double bubble airlock keeps getting sucked into fermenter - why and how to prevent?

This is caused by a drop in temp before co2 is being produced. Just cap the fermenter in sanitized foil until you're past the lag phase, or cooled to fermentaion temp. Though a little bit of starsan ...

What is necessary to keep yeast happy and healthy?

Yes you can use yeast indefinitely. However doing so takes some work. Keeping a strain unmutated requires a lab. A specific generation is usually only good for 2-3 fermentations. This is the ...

How long does it take for yeast to mutate into having other characteristics?

Yeast follow the laws of natural selection. As a cell is budding the new mass may have some minor defects / mutations. If those changes give the yeast an advantage to survive it will get passed on. ...

Reducing the taste of yeast

Can theatre buttered and salted popcorn be used for brewing brewing at home?

Yes, yes it can. Have done so before with Pumpkin Popcorn IPA. It was really good! Salted will pump up your chloride ion count, so be aware of that, and the buttered aspect makes no real difference ...

Safale S05 when is it safe to increase temperature

You want to keep the temp lower for the first 4-5 days. That's when the majority of esters are formed. After that, it's not only OK but preferable, to let the temp rise. If you need to keep it ...

Using Extract kit yeast vs some external commercial dry yeast

Usually the quality is not greatly different but the quantity is usually too low in my experience. Over here in the UK a 25l or 5Gal kit tends to come with 6g of yeast, where as I would often pitch 11-...

Washing yeast with Starsan will kill most of the yeast. Just like it kills off other microbes in your equipment when you sanitize. All stored yeast should really be used within a few weeks. I ...

Rehibernating Yeast

Your yeast should be fine. Room temperature does not hurt yeast, it just "accelerates" it, meaning it eats up nutrients faster. I do not have any experience with Omega Labs yeast, but the fresh yeast ...

Can I mix two yeasts to add different flavours when I make beer?

You can do it, but there's no way to control which will dominate so it's a crapshoot with hard to predict results. I prefer to go another way... split the batch and ferment each half with a different ...

Making pineapple beer with bakers yeast

So you have about 1kg of table sugar, and about 60g of fructose from the pineapple in a total of 5 liters of water. That should put your OG at around 1.080-1.085, depending on just how much and how ...

No, it doesn't. Bentonite is a clarifying agent, similar to Gelatin. It helps settle the yeast and other haze causing elements, but it does not kill the yeast. Sulfites don't actually kill yeast ...
