What is e-Liquid?

E-liquid, also known as vape juice, is the liquid used in electronic cigarettes (e-cigarettes) and vape devices to produce vapor. It consists of a blend of base liquids, nicotine (optional), and flavorings, all of which are heated to create a satisfying vapor for inhalation.
Despite its rising popularity, many vapers and smokers considering the switch to vaping donโt fully understand whatโs inside their e-liquid. Some worry about its safety, while others question how different types of e-liquid affect the vaping experience.
This guide will cover:
- What e-liquid is and how it works
- The core ingredients in e-liquids
- Different types of e-liquids and nicotine strengths
- How e-liquid compares to traditional smoking
- Why Black Noteโs e-liquids stand out as the best choice for tobacco lovers
By the end of this guide, youโll be able to make an informed decision about which e-liquid best suits your vaping needs.
E-cigarettes, aka JUULs and vape pens, use a battery to heat up a special liquid into an aerosol that users inhale. It’s not just harmless water vapor. The “e-juice” that fills the cartridges usually contains nicotine (which is extracted from tobacco), propylene glycol, flavorings and other chemicals.

What Is E-Liquid and How Does It Work?
E-liquid is the substance that fuels vape pens, pod systems, and box mods. When heated by a vape coil, it turns into vapor that users inhale. Unlike traditional cigarettes that burn tobacco, e-cigarettes use heat to vaporize the liquid, providing a smokeless nicotine alternative.
How E-Liquid Works in a Vape Device
- The coil inside the vape heats up, causing the e-liquid to reach its boiling point.
- The liquid turns into vapor, which the user inhales.
- Nicotine (if present) is absorbed through the lungs, delivering a sensation similar to smoking.
Since no combustion occurs, vaping eliminates the tar and toxic byproducts found in cigarette smoke, making it a potential harm-reduction alternative for smokers.
What Are the Main Ingredients in E-Liquid?
Most e-liquids contain a base liquid, flavoring, and nicotine (optional).
1. Propylene Glycol (PG) and Vegetable Glycerin (VG) โ The Base Liquids
E-liquids are primarily made of PG (Propylene Glycol) and VG (Vegetable Glycerin). These ingredients are responsible for the consistency, throat hit, and vapor production of the e-liquid.
- Propylene Glycol (PG): A thinner liquid that provides a stronger throat hit, often preferred by ex-smokers.
- Vegetable Glycerin (VG): A thicker liquid that produces denser vapor clouds and a smoother inhale.
Most e-liquids come in a PG/VG ratio, such as 50/50, 70/30, or 80/20, depending on the desired vaping experience.
2. Nicotine (Optional) โ The Addictive Component
E-liquids can contain varying nicotine levels, allowing vapers to choose their preferred strength:
Nicotine Strength | Equivalent to Cigarettes |
0 mg/mL | Nicotine-free |
3 mg/mL | Ultra-light cigarettes |
6 mg/mL | Light cigarettes |
12 mg/mL | Regular cigarettes |
18 mg/mL | Strong cigarettes |
50 mg/mL (Nicotine Salt) | Equivalent to 1+ pack per day smokers |
Nicotine is optional, and many vapers gradually reduce their nicotine intake over time.
3. Flavoring โ The Key to Customization
E-liquids come in a variety of flavors, including:
- Tobacco โ Designed for ex-smokers who prefer a traditional taste.
- Menthol โ Cooling and refreshing.
- Fruits & Desserts โ For a sweeter vaping experience.
However, not all e-liquid flavors are created equal. Many mass-produced e-liquids use artificial flavors and additives, which can impact both taste and safety.
Types of E-Liquids: Freebase vs. Nicotine Salts

Freebase Nicotine E-Liquids
- Provides a strong throat hit.
- Best suited for high-wattage devices.
- Typically comes in lower nicotine strengths (3-18 mg/mL).
Nicotine Salt E-Liquids
- Uses a different nicotine formulation for smoother inhalation.
- Allows for higher nicotine concentrations (20-50 mg/mL).
- Best for pod systems and low-wattage devices.
What are the available ratios?
Are you becoming interested in the offered ratios? After understanding the definition of ratios, you must now examine the ratios we may consider. Well, it depends on your taste. However, the most popular ratios are 50/50, 60/40, 70/30, and 80/20. These are the PG to VG ratios. All three of these ratios are favored for vape juice. The 70:30 and 80:20 proportions are quite traditional blends. They are compatible with any machine and tank and produce more flavorful and dense clouds. These ratios even boost the coils’ longevity.
In a 50/50 ratio, the amounts of VG and PG are identical. And in the 60/40 ratio, PG concentration is 60% of the overall substance, and VG concentration is 40%. Similarities exist between the 70:30 ratio and the 80:20 ratio. Here, the PG/VG ratio is 70/30 and 80/20, respectively, of the total quantity.
Difference between 50:50 and 70:30 vape juice
To better comprehend the two ratios, let’s attempt to draw a line between their alignments. A critical examination usually enhances comprehension and decision-making success. Therefore, let’s go into the assignment and outline the two viable alternatives in further detail.
Flavor
Concerning the two ratios, 50:50 and 70:30, the choice with the strongest flavor is the ratio containing 70% PG and 30% VG. There are a seemingly endless number of flavors available for purchase. While tobacco and menthol flavored E-liquids are still the most popular, there has been a recent explosion in the popularity of the fruit, candy, dessert, and breakfast cereal flavors. In addition to these basic flavor categories, several E-liquid companies specialize in creating unique and interesting flavor combinations.
Nicotine Strength
E-liquids are available in a wide range of nicotine strengths, from 0mg (nicotine free) to 36mg/ml. The vast majority of E-liquid on the market is between 3mg and 18mg/
The throat hit
Propylene glycol, or PG, is responsible for throat hits. Therefore, the one with a larger PG content will provide more hits. Thus, of the above ratios, 70:30 is the winner.
Clouds
VG (vegetable glycerin) is added to a mixture to create larger clouds. Consider purchasing the e-liquid with the highest VG content. Choose between 80:20 and 70:30 for a better viewing experience.
Discreet Vaping
If you are interested in discreet vaping, a 50:50 ratio would be the optimal choice. This ratio offers no additional value.
Once you understand the distinctions, you can make a more informed decision and determine what constitutes a suitable ratio for vape juice. This is perfect for you.
How to pick a suitable ratio for yourself?
To find a suitable ratio for vape juice, you must evaluate your preferences and comprehend the significance of each ratio. Then, match your preferences with the ratio’s characteristics.
VAPE GUIDE
New to Vaping or Black Note?
Whether you're transitioning from smoking to vaping or seeking an upgrade to natural tobacco e-liquids, Black Note has you covered. Our quick, 15-second quiz and comprehensive guide are tailored to help both smokers and current vapers discover their ideal natural vaping alternatives.
The 50:50 mixture of PG and VG provides the strongest throat impact. If you like a stronger flavor, you might select vape juice with a 50:50 ratio. If you’re transitioning from cigarettes to vaping, you may find this ratio more appealing because it’s similar to smoking. So, new vapers seeking the best option might choose this option.
Those more interested in flavor and taste should go for a 70:30 ratio
Those more interested in flavor and taste should go for a 70:30 ratio. This ratio may produce more clouds, making it ideal for hobbyists. You should know that picking up a 70:30 ratio demands more powerful technology to prevent clogging and overheating. An 80:20 ratio is best for producing large clouds. However, you should also be aware that this option might create a less intense flavor. No matter what your vaping style is, there’s a ratio out there for you. All you need to do is research and find the right one.
The 80:20 ratio is ideal for experienced vapers
If you’re experienced in vaping, you might want to try an 80:20 ratio. This is especially true if you’re looking to find it. It would help if you first understood your vaping preferences to determine the most suitable ratio. Do you prioritize flavor or clouds? Once you know what you’re looking for, finding the perfect ratio is a breeze. If you’re all about flavor, go for a 50:50 or 70:30 mixture. These ratios provide more flavor than clouds. However, if you’re looking to produce large clouds, an 80:20 ratio is your best bet. Keep in mind that this option might result in a less intense flavor.
