Vape juice, also known as e-liquid, is the liquid used in electronic cigarettes (vapes) to produce vapor. It is typically composed of a mixture of propylene glycol (PG), vegetable glycerine (VG), flavourings, and sometimes nicotine. Vape juice comes in various nicotine strengths, allowing users to choose their desired level of nicotine or opt for nicotine-free options. The flavourings used in vape juice can range from traditional tobacco flavours to fruity, dessert, or beverage-inspired options.

Determining the "best" e-liquid is subjective and can vary depending on personal preference. Some people may prefer tobacco-flavored e-liquids, while others may prefer fruity or dessert flavors. Additionally, nicotine strength, PG/VG ratio, and pricing can also play a role in choosing the best e-liquid.

To find the best e-liquid for you, it's recommended to try out different flavours and brands to see what appeals to your taste buds. Additionally, reading reviews and recommendations from other vapers can help you narrow down your options.

E-liquid comes in various sizes to accommodate different vaping needs and preferences. The most common sizes available for vape juice bottles are:

1. 10ml: This is the smallest size and is typically used as a sample or for those who prefer to switch flavours frequently. It is portable and convenient for on-the-go vaping.

2. 50ml: A 50ml bottle offers even more vape juice and is suitable for vapers who vape regularly and prefer to have a larger supply on hand. This size is popular among regular vapers who have a favourite flavour they use consistently.

4. 100ml: These larger-sized bottles are ideal for heavy vapers who use a significant amount of e-liquid. They provide an ample supply and are often more cost-effective for those who vape frequently.

5. 200ml and above: Some brands offer even larger-sized bottles for those who want to stock up on a particular flavor or prefer to buy e-liquid in bulk. These sizes are commonly used by individuals who have high vape juice consumption or prefer to have a long-lasting supply.

Remember, when selecting the size of your vape juice bottle, consider your vaping frequency, preferences, and how much e-liquid you typically go through. It's always a good idea to have a backup supply to avoid running out and to ensure continuous vaping enjoyment.
