weigh your priming sugar, don't measure the volume boil it in just enough water to dissolve it for a few minutes pour that sugar syrup into your bottling bucket rack the beer onto the sugar mixture give it a couple gentle stirs with a sanitized spoon That works for me. Hopefully it will work for you, too!

BYO has a pretty good, brief article on what yeast nutrient provides for your beer, as well as whether or not it's necessary. To summarize for you, wort by itself is pretty rich in nutrient, and may not need yeast nutrient, especially if you re-pitch yeast from a previous batch (proper amounts of slurry, of course). The one nutrient that is not present in ...

An individual yeast cell is either dead or alive. A packet of yeast will have millions to billions of cells though. Some percentage of that will be alive, and the remaining percentage will be dead. The older the packet, and the worse the storage conditions, the higher the percentage of dead yeast. Depends on the brand of kit. Some kits use no-name yeast, for ...

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 with baker's yeast and you can't leaven bread with brewer's yeast" This is completely wrong. They are both are saccharomyces cerevisiae and do essentially the ...

No way. You will kill everything in your beer at this temperature. The pasteurization process actually uses lower temps, probably with less exposure time, and kills them all. And its ok to use any beer yeast to carbonation, you don't need the same strain.

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 generated during the first 3 days of fermentation and the major difference of a high attenuation yeast will not really be apparent until the later than this ...

I advise looking at HotHead from Omega Labs: http://www.omegayeast.com/portfolio/14158-2/ Flocculation: Medium-High Attenuation: 75-85% Temperature Range: 62-98° F (16-37° C) Alcohol Tolerance: 11% ABV

Danstar BRY-97 is a great option for American-style IPAs. It starts out kind of rough, but if you give it enough time to condition, it makes an amazing beer. Fermentis Safale US-05 and Danstar Nottingham also a popular choices for American-style IPAs. You should ferment them at the low end of their temperature ranges. For English-style IPAs, you can use ...

You will need to add priming sugar if the beer has reached its terminal gravity with the yeast being used. In this example, despite the 80% attenuation the remaining 20% is not usually fermentable sugars. Its comprised of protein, dextrans and other molecules in solution that are largely ignored by your primary yeast strain. Lastly, reported attenuation ...

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 yeast, like making a starters from the same beginning yeast over and over. In my own experience, i have used the same yeast batch for 3-4 times with no changes ...

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 a plastic box of pale gray flakes. This was the kveik, which Terje got from a friend in Hornindal twenty years ago, and has been using since. Terje collects the ...

There are a number of objective, quantifiable differences between yeast strains. Temperature range. Beer yeasts are roughly categorized into lager and ale strains. All lager strains work best at low (~500 F.) temperatures, while ale strains work best closer to room temperature (~680 F.). But within either of these categories, different yeasts have different ...

The primary benefit of a starter is having the proper number of healthy yeast cells to ferment your wort. By "proper number", we mean about 0.75 million cells per milliliter per degree Plato of wort for ales, and 1.5 million cells/mL/P for lagers. (Consider that smack packs and vials have about 100bn cells when fresh, which is only enough cells for 5gl/19L ...


7

Yes (sort of... You can't just warm the bottle up and chuck it in there... It's a little more complicated than that...) but you will need to buy a good quality, bottle conditioned beer (look for sediment in the bottom of the bottle, or the words "bottle conditioned" on the label... Or ask your beer shop...) Basically, most commercial brewers (particularly ...

I can't imagine anyone suggesting bottling at a FG of 1.042 I would return them to the fermenter and allow fermintation to complete. Those are bottle bombs. Be careful. Many yeasts don't survive at 6.5% ABV, but there are plenty that do. Wine yeasts for example. At 1.042 we would call that a stalled or stuck fermentation, and a more tolerant yeast can be ...

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 cycle: Adaptation, High Growth, and Stationary. (See Yeast by CW and Jamil) They do not have a maturation phase where they clean up byproducts. Adaptation phase ...

Interestingly, I found a presentation by Thomas H. Shellhammer, professor of fermentation science at OSU, that shows the composition of a typical hop cone: Cellulose and Lignin: 40-50% Protein: 15% Alpha Acids: 2-15% Beta Acids: 2-10% Water: 8-12% Minerals: 8% Polyphenols and Tannins: 3-6% Lipids and Fatty Acids: 1-5% Hop Oil: 0.5-3% Monosaccharides: 2% ...

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 hope that nothing else gets in your wort also.

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 won't hurt much, foil is better than an open airlock IMO. I don't put air locks on until the wort is at fermentaion temp. I also remove the airlock then foil ...

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. You can have noted changes in just a few generations. I've observed in my own washing methods strains becoming less flocculant just because my washing method ...

There are good answers about removing yeast cells from existing homebrew. But your question asks about "yeast taste" - this is not just particulates. So I wanted to add an answer covering some of this. There are many flavours generated by yeast during fermentation. There are two ways to common ways minimise these flavours: Use a "POF Negative" yeast ...

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 after mash and boil, any left over fats will get taken up by the yeast. As long as you are not adding an Ounce of butter you should be fine with the small amount ...

Mostly economical, yes. Another reason is potentially limited (or non-existent) commercial availability of specific strains. Either the yeast company's seasonal strain releases or something cultivated from yeast remaining in the bottle. Another reason is to develop a "house" strain, or to modify the behavior of an existing strain. For instance, the good-...

I have ordered some Saccharomyces boulardii and plan to do a test brew this weekend. Going to do 5l/1gallon brew with only pale malt ~1040 OG. Will add a small amount of Perle or saaz depending what is in the freezer. I will report back in a week or 2, with the recipe and results. Reporting back... [21 Mar 2016] Apologies it has been a while, I got it ...

Autolysis in homebrew is largely a myth. The reason being that a five gallon batch in a carboy or bucket doesn't have the weight or geometry to compress the the yeast the way a 100 gallon or more conical can. On the other hand, you can still get off or wrong flavors from pitching too much yeast. When harvesting yeast, it typically takes time and several ...

I think what you made is safe, but there's no way to not produce alcohol with that method.

No. In fact, depending on the gravity, a smack pack might be just the "right" amount of yeast for 2.5 gallons. The Wyeast Smack packs have a "minimum of 100 billion cells in a yeast slurry", but by the time they get to you commercially, some of those cells have died off. Commercial pitch rates are about 0.75 million cells/mL/P for ales (a bit higher for ...

You can use any yeast and it will make "beer". Whether this beer is tasty is a whole different issue. If it's your only option, try it! I'll be curious to see how it turns out! You should definitely consider making a starter, especially if the source of the yeast is questionable.


6

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 cooler, you can put the fermenter in a tub of water and add ice or ice packs.

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 11-22g depending on the gravity. It is probably the fact that pitching another yeast is pitching at far higher cell counts, leading to far cleaner fermentation. ...
