1. APA/IPA yeast:
Character: Very Clean, Well Balanced, Well Mannered, Good Natured and Disciplined:) These yeasts will take a bow and make all hops, malts, and adjuncts shine to their brightest. Phenols, Esters, Diacetyl, and Astringents will be kept at bay. Temperature: 18 to 25C Attenuation: 80 to 82 %Floculation: 73 to 82%
2. German Kölsch: Character: Crisp, Delicate fruit, Somewhat Winy. This yeast is cultured straight from the cellars of Germany’s Cologne region’s peculiar (In spite of being top fermenting Ale yeasts; beers brewed with these yeasts could be and should be “lagered” post-fermentation to get crispy clean palate). Fermentation Temperature: 17 to 22C Attenuation: 75 to 82% Flocculation: 80 to 81%
Character: spicy, lightly peppery, complex Esterly flavors with a powdery haze. Fermentation Temperature: 15 to 20C Attenuation: 75 to 78%. Flocculation: Medium
4. California Steam: Character: Crisp, Clean, Slightly Fruity. Lager conditioning is a must for these yeasts to truly shine. Fermentation Temperature: 17 to 22C Attenuation: 72 to 79% Flocculation: 78%
5. Belgian Abbey/witbier Yeast: Character: Spicy, Phenolic, Floral, Earthy, and Clovelike. They cultured these yeasts and blessed them with the ability to produce most flamboyant flavors known. Loads of flavors – spices, pines, flowers and citrus fruits at different temperatures. Fermentation Temperature: 15 to 28C Attenuation: 77 to 83% Flocculation: 68%
6. German Wheat Yeast:
Character: Cloves, Banana, Bubble-Gum, Apple, and Citrus fruits. These yeasts are all about phenols, esters, and fruits, just like a true Wheat yeast should. This brewer’s yeast has a wide temperature range: 12°C-25°C, but ideally 18°C-24°C. For clove-like flavors: below 22°C. For banana flavors: above 23°C Attenuation: 86% Flocculation: <50% Character: Spicy with tones of Peppers, Cloves, Hay, Passionfruit, Grapefruit, and Lemon.
7. Kveik/Saison Yeasts:
Saison means “Season” in French. Back in the day, this was strictly brewed in country farmhouses in late winters to welcome the beautiful European summer. The yeasts give off a distinctively dry, peppery, citrusy taste. They are truly born to be “Wild”. Throw in any sugars, weird malts, adjuncts, and see how they turn the flavors around. This beer yeast has a l ow flocculating strain, so use Irish moss. Fermentation Temperature: 17 to 27C, Attenuation: 85%, Flocculation: Low
8. Barley Wine: Character: This is very distinctive, with an earthy hoppiness, a wineyness, lots of fruit, and toffee flavors. It tastes like cask-aged ales and the residual sweetness can be paired with heavy hoppiness. For high gravity (8-12% v/v brews) Fermentation Temperature: 15 to 20C Attenuation: 75 to 78% Flocculation: high

Methanol a.k.a. wood alcohol is generated from fermenting wood, pectin, skins of fruits, and distillation. There is a simple WHO-approved test to check for dangerous levels of methanol. The various strains of brewer’s yeast aka Saccharomyces cerevisiae that we stock will produce ethanol by fermenting glucose (grape sugar), maltose (grain sugar) and fructose (fruit sugar). Methanol is a toxic byproduct of fermentation, but its levels are so low that unless you distill your homebrew, you should be safe. If you still want to test for methanol levels, please refer to this document.
Acetaldehyde is one of the several precursor compounds produced by yeast during fermentation. It has a green apple-like aroma and flavors and is common in young beer and mead.
Glucose >> Pyruvic Acid >> Acetaldehyde >> Ethanol
Although Acetaldehyde is a natural precursor to ethanol formation, its residual levels in the finished brew is not desirable. At excessive levels, it might even give a paint solvent/ nail polish smell. Here are the few causes for this off-flavor:
- Insufficient healthy yeast count. Many home brewers end up with old or improperly stored yeast. Also to save cost and time some brewers sprinkle the dry yeast on their wort. Making a vigorous starter batch and ensuring adequate oxygen and nutrients reach the yeast.
- Fast Pressure Brewing. A brewery under pressure to churn batches as quickly as possible tries to ferment alcohol as fast as possible. This does not give yeast enough time to metabolize the precursor compounds completely. This problem is larger for lagering than for ale.
- Another reason for acetaldehyde is fermenting inverted sugar instead of natural unpasteurized honey during mead making. Adulterated packaged honey is therefore avoided by mead makers.
- 48 hours of Diacetyl rest for lagers and ales. Slightly warm conditioning and patience are all it takes for the yeast to complete its task.
- In mead tasting like acetone: Allow it to age for at least 6 months. High sugar and natural compounds in honey prevent yeast activity. Hence it takes it longer to clear up.
Does your homebrew have the stench/ smell of a skunk? It is a result of improper handling and storage of beverages (especially imported bottles). Hops react to riboflavin (from grain) under UV light to produce this skunk flavors. This is the reason why we keep the beers in dark bottles away from sunlight.
That being said, white wine is also very susceptible to UV light. In wine, it is called ‘goût de lumière’, which means the taste of light, especially in sparkling wine. In some light beers, patrons add a slice of lime before serving. This is to mask these skunk notes.
Ever wondered why Corona beer is served with lime? Imported beer in the clear glass gets skunk and citrus notes help mask the off-flavors.
Estery: It is the aroma and/or flavor of any ester (fruits, fruit flavorings, or roses). I like a few banana notes with my wheat beers but too much of anything is undesirable. The usual culprit is poor temperature control. Each yeast has different thermal sensitivity. The same yeast can give clove flavors at low temperatures but banana/fruity notes at high temperatures. Maintaining lower and constant temperatures is the key to keep them manageable.
However, isolating the contribution of the fruity notes from the fruits/ flowers/ hops and that from the yeast cannot be done without access to the recipe. Making tea from the ingredients is the first step towards understanding these notes before altering the fermentation temperature conditioning.
This could be due to a variety of reasons.
- Firstly improper mashing leads to many unfermentable sugars.
- Secondly incomplete fermentation due to poor yeast health. One of the easiest ways to replicate this is by using baker’s yeast for making beers from the same wort.
- Stuck Fermentation.
Although Indians have a slightly sweet palate, excessive sweetness in beer is a flaw. To deliberately introduce residual sweetness, one could use crystal/ caramel/carapills malts. Milkshake IPA and milk stouts have added lactose (an un-fermentable sugar) to get a balanced sweet palate.
Yeast is a living creature that is shipped in a dormant condition. So like any organism, they have a shelf life from 3 days to 24 months. It is always important to buy yeast from a reputable store and ensure that it is kept in a cool dry place (away from sunlight and not in the freezer). Using bad yeast means that all the effort you put into making the homebrew will go to waste. There are Four kinds of yeasts used in home brews.
- Dry Yeast (like the ones sold at arishtam) They have an 18-24 month shelf life.
- Commercial Liquid Yeast: which has a shelf life of 1 week. If you are buying imported yeast, it might be difficult
- Self-propagated cultures: You could take some yeast sediment (trub) from your previous batch, wash the yeast, and maintain the culture. As long as you can keep it in the refrigerator and feed it every 3rd day, you can keep it for years.
- Slants: Seasoned pro home brewers can maintain their slant bank in agar medium for 3 years by freezing them. Home oven-dried yeast is usually able to survive 1 month of storage.
Yeast is the single-celled microorganisms that are responsible for fermenting sugar (maltose, glucose, fructose, sucrose, etc.) to ethanol. In the absence of oxygen, these yeasts do the transformation which converts your grain/fruit into a beverage. Yeast nutrients, on the other hand, are food for the yeast. On their own nutrients achieve nothing more than making a comfortable home for the yeast to function at its best capacity. Yeast energizer, on the other hand, is an SOS remedy needed to recover from stuck fermentation or incomplete fermentation or excessively low-temperature fermentation which can make yeast sluggish.
Although Yeast Energizers are types of nutrient blends, they also contain components such as vitamin B, diammonium phosphate, tricalcium phosphate, magnesium sulfate, and yeast hulls. Yeast energizers are particularly useful to restart a Stuck Fermentation, as it allows yeast populations to increase in a batch of beer or wine which likely has been depleted of these components due to an earlier yeast population growth. The additional components included in Yeast Energizers are most effective when for high gravity fermentation (high sugar high alcohol), low-temperature lagering, excessively low pH, high ash content (molasses) and other extreme fermentation styles.
Typically bottled home brew beer has a shelf life of 6 months. However, most home-brew beer is consumed within a week to a month of bottling or kegging. However, some people regularly store homebrew beer for up to 6 months successfully. Beyond this, the beer is still safe for consumption, just that it will not taste fresh. However, a couple of factors need to be taken into account to determine the shelf life.
- Storage temperature: Beer is like wine, higher the temperature the faster is the degradation in flavors.
- UV light: Even a couple of hours in direct sunlight can ruin a perfectly fresh beer
- Packaging: Microbrewery Growlers don’t last 2 days because the beer was oxidized during filling. If you see packaging in proper crown sealed glass bottles or stainless steel kegs, 6-12 months life is easy
- Oxidation: Once you open the bottle, drink within an hour.
Till 1970, dry yeast was not used commercially for brewing. Most breweries would save a bit of the trub and use it for their next batch. Even bakers would mix a part of their old dough to leaven their new batch of bread. This practice has seen a comeback due to the resurgence of sourdough technique in baking.
Traditional Wine makers throughout Europe would cultivate the yeast biome. They would compost the lees and all the organic residue from the wine making process. This compost is used as a natural organic fertilizer for their fruits and grapes. In doing so the yeast strain that the particular unique natural strain of yeast (which is locally available and isolated) would dominate the biome. The fruits now just need to be juiced and they will start fermenting naturally.
Kveik yeast is also usually harvested and rarely cultured. Traditional households would make special oak rings or towers that they would insert in their brew. The yeast would attach themselves to the wood and this wood would be used to inoculate the next batch.
How to Harvest Liquid Yeast at Home
Today we are going to talk about how to harvest yeast from your old batch. Depending on which school of yeast harvesting you follow, you can either top-crop or bottom crop your yeast. If you are using a conical fermenter, then it comes with a free yeast harvesting attachment. Once you have harvested the yeast, you should wash it. Doing so will get it rid of all the hops and sediments which can lower
You can choose to use fresh liquid yeast by adding some yeast nutrient and making a starter culture. Post that you can:
- Use the wet yeast as is. Keep feeding it every 3rd day with some fresh wort to keep it alive. Store it in the refrigerator dairy section (4 degrees) so that its metabolism is reduced. Best if you are planning to reuse the yeast within a month.
- Make slants using glycerine. This will allow you to freeze them and store for ~2years
- Dry the yeast. Especially Kveik. The home-dried yeast typically have a shelf life of 90-180 days.
Yeast is responsible for carrying out the fermentation process in beer making and overall brewing. This is one of the most important part of brewing. Yeast takes up sugars like maltose, glucose and produces carbon dioxide and alcohol. It has the credit for providing various beer styles. The brewer picks up the yeast according to the recipe or the style of the beer they want to make.
Yeast is either an ale yeast or a lager yeast. The former involves warm temperatures while the later needs cool temperatures. This difference in temperature produces different flavor and aroma characteristics and thereby providing various beer styles.
Both beer yeast and bread yeast are products of a single-celled fungus called Saccharomyces cerevisiae. But they are formed from different strains of this species. The main difference between beer or brewer’s yeast and baker’s or bread yeast is that brewing requires yeast that can produce CO2 and alcohol whereas baker’s yeast has a much stronger focus on the CO2. Bread yeast is primarily used as a raising agent whereas brewers expect the yeast to be virile and reproduce at a fast rate that will transform the sugary wort into a drinkable beer.
There are plenty of examples of these two being used interchangeably. However, each comes with it’s own precautions and aspects to be taken care of.
