You can add more yeast to a stuck fermentation, but there are a few things you should consider first:
Wait for one day before determining whether your ferment is stalled or not. Some brews are very slow and releases tiny, difficult to spot bubbles whilst others will ferment like crazy. A sure fire way to check if a ferment has stalled is to siphon some of the liquid into a plastic bottle and screw the lid on tight. Leave it for about an hour (in the sink or bath tub) and if the bottle expands, your yeast is active.
If you are certain your yeast is stalled. Try to identify why this has happened before adding any more, if conditions aren't right you'll only be sending more yeast to their death which can ruin the flavor in the long run.
Different yeasts have different temperature thresholds, too hot or too cold could kill the yeast or put it to sleep. Check the conditions your yeast works best in and, if appropriate, try to relocate your carboy/brew bin to a warmer or cooler location before adding more.
Certain brewing additives can also kill your yeast, such as sodium metabisulphate (present in Campden Tablets, stabilisers and some sterilizing agents) - if you have used any additives, make sure twenty four hours have passed before doing anything else.
Once you have gone through the above and are certain you have done your due diligence in trouble shooting - you can add more yeast. The best way to do this is through the 'starter bottle' method. Siphon some of the liquid into a small glass or bottle, add your yeast (following any instructions required to activate it) and wait. Once the contents of the glass or bottle have started to foam, you know that yeast is active. Go ahead and tip it back into your carboy or brew bin.

How is the process of brewing lager beer different from other types of beer?
The process of brewing lager beer is different from other types of beer mainly because of the yeast and fermentation temperature used. Lager beer is brewed with bottom-fermenting yeast at cooler temperatures, resulting in a cleaner and crisper taste compared to ales, which are brewed with top-fermenting yeast at warmer temperatures. This longer, colder fermentation process gives lager beer its characteristic smoothness and lightness.
Is hops the fermenting agent that converts the wort into beer?
No yeast, is the fermenting agent used to make beer.
What micobes are in beer?
Generally yeast is the main agent in fermenting beer.
What is product of glucose and yeast?
fermenting glucose and yeast produces beer and wine.
What is the difference in production processes of ale beer and lager beer?
The main differences between ale and lager production are in temperature and type of yeast used. Lager is fermented at a lower temperature than ale and uses a bottom fermenting yeast whereas ale uses a top fermenting yeast.
What is lager and clarification in brewing beer?
A lager is fermented at relatively cooler temperatures using bottom-fermenting yeast. Compare to an ale, which uses top-fermenting yeast at warmer temperatures. Clarification is the precipitation of the yeast from the finished brew.
How much yeast should be used for brewing beer?
The amount of yeast needed for brewing beer varies depending on the recipe and batch size. Typically, a packet of yeast or a liquid yeast culture is sufficient for a 5-gallon batch of beer. It is important to follow the specific instructions provided with the yeast strain being used to ensure proper fermentation.
What distinguishes mead from beer in terms of ingredients and production processes?
Mead is made from honey, water, and yeast, while beer is made from malted barley, water, hops, and yeast. The production process for mead involves fermenting honey and water, while beer involves mashing barley, boiling with hops, and fermenting.
What is brewers yeast?
Brewer's yeast is an ingredient that is used to ferment sugars to alcohol in the brewing of beer.
What is a gill of yeast as used in recipes from the Colonial Era?
A gill is a half cup. A gill of yeast would have been a half cup of brewed yeast or beer. Colonial era housewives, often called ale wives, would brew the beer or ale for consumption by the whole family. Yeast was necessarily grown in this manner for use in bread making as well as ale or beer making, often in a cool room adjoining the kitchen, so that a gill of yeast would have been a half cup of this brew kept fermenting for this purpose. Today's equivalent would be about a tablespoon of active dry yeast.
Is barley used to brew Corona beer?
Yes, along with rice and/or corn, hops, and a number of other ingredients.
What is the process of brewing beer with wine yeast and how does it affect the flavor profile of the final product?
When brewing beer with wine yeast, the process involves fermenting the beer with the wine yeast instead of traditional beer yeast. This can result in a different flavor profile for the final product, as wine yeast may impart unique flavors and aromas to the beer. The specific impact on flavor will depend on the type of wine yeast used and the brewing process, but it can potentially add fruity or floral notes to the beer.
