How Much Priming Sugar Per 12 Oz Bottle Should You Use

How Much Priming Sugar Per 12 Oz Bottle Should You Use? [Answered]

Trying to brew beer for the first time, but can’t determine the exact proportion?

It is frustrating, we get that. This is why we have calculated the basic proportions for you. So that you can brew tension free. 

So, how much priming sugar per 12 oz bottle should you use? 

It is best to add priming sugar in liquid form. Here, You can use corn sugar and table sugar for your fermented beers. Then, 1 teaspoon of it will be equivalent to dry sugar. For a 12 oz bottle, use ¾ teaspoon of corn sugar. And, if you are using table sugar, use ½ teaspoon.

Now you know the basic portions. But, to know elaborately, about how to make priming sugar and calculate, keep reading!

What is Priming Sugar and Its Purpose? 

Priming sugar is a sugar that is added to a fermented beer. This sugar is added for re-fermentation or secondary fermentation. It is used for carbonating and to add flavor and aroma to beers. Priming sugar also adds fizzle.

Sometimes the sugar might be added as solid cubes. But mostly, it is added as a liquid right before the bottling process.


On the other hand, yeast and priming sugar is added to the fermented beer. And,  the yeast absorbs the sugar. Therefore, the end result of this process is carbonation by giving out carbon dioxide. 

Here, priming sugar offers the yeast more sugar to operate with. It helps minimize some risks of carbonation failures allowing yeast to live longer. However, keep your beer from an excessive amount of yeast.

Well, let’s get to the next segment, to use priming sugar the best way. 

What Are the Types of Priming Sugar for Brewing?

Now, let’s get to the types of priming sugar that can be used for brewing. Basically, you can use any sugar but, there are a few differences. Such as, if you use regular table sugars, it will do the work. But it will not add flavor or aroma to your beer. 

On the other hand, corn sugar is also quite great as priming sugar. Corn sugar will not affect the taste of the beer significantly. But, it will help you with carbonating beer very easily. 

However, natural darker sugar will give your beer a more flavored taste. It will also provide the beer with a nicer aroma and fizzle. 

How to Use Priming Sugar?

We know the most common priming sugars are all highly fermentable. These sugars will ferment off completely under ideal conditions. And leave no lingering sweetness in the finished beer.

Here, we have said above, it is best to use priming sugar in liquid form. Therefore, for preparing the sugar syrup, take 1 ½ cups of corn sugar. Add 1 cup of water to it and mix well in a saucepan

Then, Stir nicely and thoroughly. And, bring it to keep it below the boiling point for a while. Keep a close eye on the mixture so that it does not boil for more than a minute. 

Because boiling it for more than one minute can evaporate the water in it. And the proportions will not work well for the mixture. 

After simmering, the volume of the mixture will be 12 fluid ounces. And, 1 teaspoon of dry sugar will be equivalent to 1 teaspoon of the mixture. Now, your priming sugar is ready to use. 


Also, this bottle conditioning can increase ABV slightly. By this, you can fix how much sugar is for secondary fermentation to use. 

How Much Priming Sugar Per 12 Oz Bottle Can Be Used?

Here, we are going to discuss both corn and table sugar for your better understanding. We know, beers are made in batches, not one by one. Therefore, we are going to show you a calculation of how much sugar to use. Stay with us!



your batch volume is 1 gallon and the amount of corn sugar used is 0.884 ounces. 

Now, converting ounces to grams, 

We know, 

1 oz = 28.35 grams

So, 0.884 oz = (28.35 x 0.884) grams

                     = 25.06 grams 

Now, converting gallons to ounces, 

1 gallon = 128 oz

So, batch size = (1 x 128) oz 

                          = 128 oz 

Here, we have to divide batch size with the bottle size,

So, total bottles = (128/12) 

                          =10.67 bottles

Finally, we have to divide grams of corn sugar by the number of bottles. 

(25.06/10.67) = 2.35 grams priming sugar per 12 oz bottle.

We know, for corn sugar

2.5 grams = ¾ teaspoon 

So, the amount of corn sugar is ¾ teaspoon per 12 oz bottle.

And, for table sugar, 

The same calculations go for table sugar. Here, we have taken 0.806 oz for 1 gallon.

Converting ounces to grams, 

We know, 

1 oz = 28.35 grams

So, 0.806 oz = (28.35 x 0.806) grams

                     = 22.85 grams

Now, we have to divide grams of table sugar by the number of bottles.

(22.85/10.67) = 2.14 grams per 12 oz bottle.

We know, for table sugar

2.14 grams = 1/2 teaspoon per 12 oz bottle of beer

So, for a 12 oz bottle, you have to add ¾ and ½ teaspoons of corn and table sugar. 

Furthermore, you can utilize a priming sugar calculator for accurate results. 

With the calculator, you can also determine how much priming sugar is for 5 gallons. Not only that, you can figure out how much priming sugar per litre cider is required.


Now, you can also differentiate between 12 oz and 16 oz beer. And, if you want to go for bigger batches, calculate the ingredients accordingly. 


Can Bottle Priming Enhance the Level of Alcohol?

Yes, bottle priming can enhance the level of alcohol to some extent in the beer. But, the ABV generated by the initial fermentation is usually not much different. To aid secondary fermentation, priming sugar is added. Bottle priming does not bring a big change in the alcohol level. 

Can You Stir Homebrew Before the Bottling Process? 

The answer is no. You should not stir homebrew before the bottling process. Because the bottles will be filled with yeast. And, the sediment will settle down in the bottle and take more time than usual. Bottles, where they have more yeast, will take a long time 

When Can You Drink Homebrew After Bottling?

You have to stay out of drinking it for at least 2 weeks. Because the yeast needs time for consuming the liquid priming sugar. After consuming it, the beer will take time to absorb carbon dioxide. If you open the bottles before that, they will be unfinished. 


Hope you can now determine how much priming sugar per 12 oz bottle to use. For corn and table sugars, you should add ¾ and ½ teaspoons respectively. 

We hope this discussion has been helpful for you. Till next time. 

Good luck with your brewing!
