How Many Drinks Can You Make with One 8g Carbon Dioxide Soda Charger?
Table of Contents
Carbonated drinks are a refreshing delight, and with the growing popularity of DIY soda makers, many people are turning to 8g carbon dioxide soda chargers to carbonate water and beverages at home. But a common question arises—how many drinks can you actually make with just one 8g carbon dioxide charger?
In this article, we’ll explain everything you need to know: what an 8g carbon dioxide charger is, how it works, how many drinks it can make, how to use it properly, and how to get the most fizz for your money. Let’s dive in.

What Is an 8g Carbon Dioxide Soda Charger?
An 8g carbon dioxide soda charger is a small, disposable 8-gram cartridge of compressed, food-grade carbon dioxide gas. Those small chargers are designed to carbonate beverages—most typically water—using compatible siphons or makers for soda. Each charger is sealed and under pressure, and punctured in an appliance, it releases carbon dioxide into the liquid, creating those great bubbles we love so much.
Carbon dioxide (CO₂) is a harmless gas naturally and entirely safe to ingest if of food grade. It’s the identical gas that mass-produced soda beverages utilize to give their fizz.
The chargers are utilized in homes, restaurants, and bars for:·
- Producing carbonated water
- Making fizzy cocktails
- Fizzy fruit juices or chilled teas
They are simple to use, portable, and compatible with most standard soda siphons or carry-along soda makers.
How Many Drinks Can You Get from One 8g Carbon Dioxide Charger?

8 Gram CO2 Soda Chargers
This is something home users and hospitality industry professionals both want to know. Here’s the short answer:
One 8g carbon dioxide charger will carbonate roughly 1 liter (roughly 34 ounces) of water.
So, depending on your glass size and how fizzy you like your drink, you can usually get:
- 3 to 4 average servings (8–12 oz per glass)
- 2 tall servings if served in tall glasses or if extra fizz is added
- 1 liter bottle of fizzy water that will be ready to mix with syrups or flavorings
Why the Amount Might Vary
While 1 liter is a typical measurement, some things come into consideration which might influence how many drinks you actually have:
- Water temperature: Cold water is more efficient at dissolving carbon dioxide, so you’ll get improved carbonation
- Effectiveness of the device: Some siphons work more effectively with gas than others
- Level of carbonation wanted: Want a little more fizz? You might need a larger quantity of gas per liter
- Quantity of water: Tightening your bottle too much can waste gas and reduce efficiency
By being careful with your technique and using cold water, one 8g carbon dioxide charger can give you the same solid, restaurant-style bubbles every time.
How to Make Soda Water with an 8g CO2 Charger?
Homemade soda water preparation is simple and quick. You will not require a huge machine or an expensive device. Your compatible soda siphon and 8g carbon dioxide charger are all you need.
What You’ll Need:
- A soda siphon or portable soda maker (compatible with 8g carbon dioxide chargers)
- A single 8g carbon dioxide soda charger
- Cold water (refrigerated for best use)
- Optional: lemon, syrups, mint, juice, etc.

Step-by-Step:
Step 1: Prepare Your Equipment
Before you start, please make sure that your soda maker or your siphon is clean and dry. Inspect the seals and valves to ensure they are fine so that there won’t be any gas leak.
Step 2: Fill the Bottle with Cold Water
Remove the bottle from the soda siphon and charge it with cold fresh water to be filled to the marked fill line (approximately 3/4 full). It is important to use cold water because carbon dioxide dissolves more in cold liquids than in hot liquids, forming better carbonation.
Step 3: Tuck the Bottle Back onto the Soda Siphon
Carefully screw the bottle back onto the siphon or soda maker head until snug and tight. Avoid cross-threading it. Align it right to avoid leaks.
Step 4: Insert the 8g Carbon Dioxide Charger
Utilize one 8g carbon dioxide charger and place it in the charger holder on the soda siphon. Tighten the charger holder on the siphon head firmly. You should notice a definite “hissing” when the gas ejects and starts to carbonate the water.
Step 5: Shake the Bottle Gently
As instructed on your device, shake the bottle 5–10 times gently. This dissolves the carbon dioxide gas evenly into the water, making sure that they form even bubbles. Avoid over-shaking to ensure that there will be no excess pressure.
Step 6: Let It Rest for a Moment
Place the bottle upright for 1–2 minutes. The resting time ensures that the carbonation process reaches completion, making the bubbles last longer in your soda.
Step 7: Pour Your Fresh Soda Water
Carefully press the siphon lever or slowly open the spout to pour your freshly carbonated soda water. Enjoy it on its own or with your favorite flavorings like lemon, fruit syrups, or herbs.
Step 8: Store Any Remaining Carbonated Water
If you’re not going to drink the entire soda water at once, make sure to cap the bottle tightly and store it in the fridge so as to maintain the fizz for several hours.

Want More Fizz per Charger? Try These Tips
Want to get the most from each cartridge? These helpful tips optimize efficiency:
Use Chilled Water
Cold water holds carbon dioxide much better than room temperature water or hot water. Store your water in the fridge before carbonating.
Don’t Overfill
Fill to the line on your siphon or soda bottle. Excess filling reduces carbonation efficiency and wastes gas.
Don’t Rush
Allow the bottle to rest for 30 seconds to 1 minute after charging. This enables full dissolution of the carbon dioxide in water prior to consumption.
Keep Your Equipment Clean
A well-maintained, clean carbonator or soda siphon ensures smooth gas transfer and does not leak.
Store Cartridges in a Cool Place
Carbon dioxide is a temperature-expanding gas. Placing chargers in a cold area reduces the risk of leakage or pressure loss.
