What is Priming Sugar?
Priming sugar, also known as bottling sugar, is a type of sugar that is added to beer just before bottling. The sugar is then consumed by the remaining yeast in the beer, which produces carbon dioxide, creating carbonation in the bottle.
There are several types of sugars that can be used as priming sugar, including table sugar, corn sugar, turbinado, inverted sugar syrup, and Belgian candy sugar. Each type of sugar will impart a slightly different flavor and level of carbonation to the beer. Therefore, it’s important to choose the right one for your recipe.
How Do I Know Which Priming Sugar to Use?
Ultimately, the choice of which sugar to use for bottle priming is up to you and the flavors you wish to imbue in your homebrew. To help you choose, here are some of the characteristics of the common priming sugars:
- Corn Sugar: Also known as dextrose, corn sugar is a popular choice for priming beer. It is highly fermentable and produces a clean flavor profile that doesn’t alter the taste of the beer.
- Table Sugar: Table sugar, also known as sucrose, is another option for bottle priming beer. It is readily available and inexpensive, but it can sometimes produce a slightly cidery taste if used in excess.
- Honey: Honey can be used as a priming sugar and can add a unique flavor and aroma to the beer. However, it is important to note that honey is less fermentable than other sugars, so it may result in a lower carbonation level. (And yes, honey beer is a thing!)
- Malt Extract: Some homebrewers choose to use malt extract as a priming sugar. This can add additional flavor and complexity to the beer, but it is important to use the appropriate amount to avoid over-carbonation.
- Belgian Candi (Candy) Sugar: Belgian Candi Sugar is a highly fermentable sugar that is commonly used in Belgian-style beers. It can add a unique flavor and aroma to the beer, but it is also more expensive than other types of priming sugars.

What Does Bottle Priming Mean?
You may hear other homebrewers discussing priming sugar and bottle priming and wonder what they are. More importantly, are they the same thing? Bottle priming is the technical name for the process using in homebrewing beer to carbonate the near-finished product. After the beer has finished fermenting in a secondary vessel, priming sugar is added to the beer before bottling. The priming sugar is then consumed by the remaining yeast in the beer, producing carbon dioxide that carbonates the beer. The carbon dioxide produced by this process is trapped inside the sealed bottle, creating the carbonation that is characteristic of beer.
If you do not want to force carbonate your beer with CO2 tanks, bottle priming is the next best thing.
How Much Priming Sugar Do You Need?
Too much or too little sugar can be disastrous for you beer, so you want to make sure you get it right. The amount of priming sugar you use will depend on the style of beer you’re making, as well as your personal preference for carbonation levels. A general rule of thumb is to use around 3/4 to 1 cup of priming sugar per 5 gallons of beer. However, it’s always best to consult a priming sugar calculator to get an accurate measurement for your specific recipe.
Curious about how much priming sugar per bottle you need? To calculate the amount needed per bottle, you first need to determine the volume of CO2 desired. This can vary depending on the beer style, but a typical range is between 2.2 and 2.8 volumes of CO2. Once you have determined the desired volume of carbon dioxide, you can use a priming sugar calculator or formula to calculate the amount of sugar needed per bottle.
For example, if you have a 5-gallon batch of beer and want to carbonate to 2.5 volumes of CO2, you would need approximately 4.5 ounces (128 grams) of priming sugar. If you plan to bottle 50 12-ounce bottles (355 ml), you need to add about 0.36 ounces (10 grams) of priming sugar per bottle.
When to Begin Bottle Priming Your Beer
When brewing beer, it is important that everything is done in the proper order. You cannot begin bottle priming while fermentation is incomplete. As such, priming sugar should be added to the beer just before you wish to start bottling, commonly referred to as “bottling day.”
You should not start bottle priming too soon or too late. If priming sugar is added too soon, before the yeast has finished fermenting all of the available sugars, there may not be enough yeast left to properly carbonate the beer. On the other hand, if priming sugar is added too late, after the yeast has already been removed or has died off, the beer will not carbonate at all. It’s important to wait until the beer is at the proper stage of fermentation before adding priming sugar. Typically, that is when the beer has reached its final gravity and has no more active fermentation.
How to Use Priming Sugar When Bottle Priming
So far, we have established that priming sugar is a crucial step that can make or break your beer. Without priming sugar, you won’t have those bubbles dancing on your tongue with every sip. While bottle priming beer is a relatively straightforward process, it is important to follow the steps completely. Don’t skip over anything. Otherwise, you may end up with over- or under-carbonated beer!

Or if you would rather read the directions, here’s a step-by-step guide on how to use priming sugar to properly bottle prime your beer:
Step 1: Calculate the Amount of Priming Sugar You Need
The amount of priming sugar you need depends on the style of beer you’re brewing, the volume of beer you’re bottling, and the level of carbonation you desire. There are plenty of online priming sugar calculators available, but a general rule of thumb is to use around 3/4 to 1 cup of corn sugar (dextrose) per 5 gallons of beer.
If you want to go a bit more in-depth with these calculations, you are going to need the formula to figure out how much priming sugar you need. The formula commonly used is: (V * (CO2 – 3.0378) * 2.535) / SG. The V is the volume of beer in gallons, CO2 is the desired level of carbonation in volumes, and SG is the specific gravity of your beer at the time of bottling. The 3.0378 and 2.535 are conversion factors.
However, to save your brain from arithmetic, there are plenty of bottle priming calculators available online for free use, such as the one mentioned earlier.
Step 2: Clean and Sanitize Your Bottle Equipment
Before you start bottling, make sure your bottles, caps, and bottling equipment are all thoroughly sanitized. Any bacteria or contamination can ruin your beer, so it’s important to take sanitation seriously.
Although you may already know how to clean and sanitize your brewing equipment, here are some steps to prevent any contamination:
- Always clean your equipment first with hot water and mild detergent. Rinse the detergent thoroughly.
- There are many sanitizing solutions available out there. Choose the one that is best for you. Follow the manufacturer’s instructions when mixing the solution together.
- Once you have prepared the sanitizing solution, soak all of the equipment thoroughly. Generally, you should wait between 30 seconds and a couple of minutes. You do not have to soak the equipment for too long.
- Rinse off the equipment with clean water.
- Let everything air dry. Do not use a towel or cloth to dry off the equipment, as this may spread bacteria.
- Now your equipment is ready for use.
Step 3: Boil Your Priming Sugar
To ensure that the priming sugar is evenly distributed throughout your beer, it’s best to dissolve it in a small amount of boiled and cooled water before adding it to your bottling bucket. You can use a ratio of 1:1, meaning one cup of water for every cup of priming sugar. Optionally, you can adjust the ratio based on the amount of sugar needed. Boil for about 10-15 minutes, then let the priming sugar solution cool to room temperature before proceeding.
Step 4: Add the Priming Sugar Solution to Your Beer
Once the priming sugar solution has cooled, you’re ready to add it to your beer. The easiest way to do this is to rack the beer from your fermenter into a bottling bucket, leaving behind any sediment or trub at the bottom. Make sure you avoid as much sediment as possible. One of the best ways to do that is to make sure your fermenter is positioned higher than the vessel you are siphoning the beer into. This helps create a natural flow and prevents any unnecessary agitation of the sediment at the bottom of the fermenter.
Use a sanitized spoon or paddle to gently stir the beer and sugar solution together to ensure even distribution. Do not be too zealous about it, though. You do not want to splash or aerate the beer.
Step 5: Bottling Your Beer
Now for the fun part: bottling your beer. Attach a bottling wand to the end of your siphon and fill each bottle to the desired level, leaving about half an inch of headspace at the top. Use a bottle capper to seal each bottle with a sanitized cap. Make sure the caps are securely in place and give the bottles a gentle swirl to help distribute the sugar evenly.
Unfortunately, the bottle priming is just beginning.
Step 6: Now For Conditioning
Brewing beer is a labor of love and patience, especially when you need to wait for it to sit and carbonate. This process is known as bottle conditioning, and it usually takes about 2-3 weeks. You must find a cool, dark place at a consistent temperature between 60-70°F.
During the next 2-3 weeks, the yeast remaining in the beer will start to consume the priming sugar. Carbon dioxide is a byproduct of this consumption. As the CO2 gathers, your beer will be naturally carbonated.
Step 7: Drink Up!
Finally, the moment you’ve been waiting for. Crack open a bottle and pour your homebrew into a glass. You’ll notice a beautiful head of foam, and the carbonation will give your beer a pleasant and refreshing effervescence. Savor the flavors, aromas, and mouthfeel of your creation, and be proud of the fact that you made it yourself.
In a Hurry? Try Priming Sugar Tablets
Now, there is a way to avoid the whole process of measuring out the priming sugar of your choice, dissolving it, and then bottling your beer from there. The more convenient option would be priming sugar tablets. They are pre-measured tablets of sugar that you can add to your beer during bottling in order to create carbonation. The tablets come in various sizes, typically ranging from 3 to 5 grams per tablet. You can choose from a variety of sugars, including dextrose, sucrose, and maltodextrin.
One of the biggest pros of using priming sugar tablets is convenience. Since they are pre-measured, you don’t have to worry about measuring out the right amount of sugar. Also, you don’t have to make sure it’s evenly distributed throughout the beer. This can be especially helpful if you’re brewing a large batch of beer and want to make the bottling process as efficient as possible.
Another benefit of using priming sugar tablets is consistency. Since each tablet contains a precise amount of sugar, you can be confident that each bottle of beer will have the same level of carbonation. This can be especially important if you’re entering your beer into a competition or giving it as a gift. In other words, if you are a perfectionist, the pre-measured method may be ideal.
This may sound like a dream come true, but there are a few caveats. First, the priming sugar tablets may not dissolve completely, which increases the likelihood of uneven carbonation or a dreaded bottle bomb. Another drawback is the expense. Purchasing tablets is useful when you are working with a smaller batch while buying priming sugar in bulk is better when you are trying to be more industrious.
Delicious Beer With Bottle Priming
Bottle priming with priming sugar is an essential step if you want to carbonate your beer just right. By using the steps outlined above, you should have no problem carbonating your beer to your liking. It may take some trial and error, however, to strike that balance between how much sugar you need for a specific amount of fizz. With a little practice and attention to detail, you can create a carbonated beer that is every bit as good as your favorite craft brews. So, go ahead and give it a try—your taste buds will thank you.
Frequently Asked Questions
Priming a bottle of beer refers to the process of adding a small amount of sugar to the beer. The goal is to develop carbonation. The sugar is consumed by the yeast, creating carbon dioxide as a byproduct. This carbon dioxide then dissolves in the beer, forming bubbles, known as carbonation.
There are many types of priming sugar, and each of them have benefits that may add to your beer. The two most popular options are dextrose (corn sugar) and sucrose (table sugar). Weigh the pros and cons and consult with the recipe you are following before deciding.
To achieve this level of carbonation, a commonly used amount of priming sugar is 3-4 grams per 16 oz bottle of beer. Make sure the priming sugar is evenly distributed to avoid over- or under-carbonation.
