Can Higher Nicotine Strengths Affect an E-Juice’s Flavor?

When we shop for e-liquid, there are two things that we are primarily concerned with: flavor profile and nicotine strength.  One of the wonderful things about vaping is that we can choose from a wide variety of flavors and nic strengths for a more customized experience that uniquely suits our preferences and desires.

But what if the nicotine strength that you choose actually plays a role in how your vape juice tastes?  We have been asked often whether or not higher strengths of nicotine actually impact the flavor of the e-juice.

In Short, Yes

Yes, the level of nicotine in your e-liquid can impact how it tastes.  E-liquids contain four basic ingredients: nicotine, vegetable glycerin, propylene glycol and flavoring.  As these ingredients mix and meld together, they bond molecularly and change each other.  Furthermore, the nicotine in e-juice carries the flavor molecules into the mouth in a way that can change how you experience the taste of your vapes.

Higher Nicotine Strengths Seem to Promote Stronger Flavor

Generally, higher nicotine strengths tend to offer a stronger flavor experience.  

  • One reason for this is because the nicotine molecules may intensify the potency of the flavor molecules.  
  • Nicotine enables the delivery of flavor molecules in a unique way.  For instance, we know that stronger nicotine levels produce a stronger throat hit, which is the sensation of the vapor hitting the back of your throat.  This means that high-nic vape juices feel different when they are inhaled.  That unique feeling may come with a more potent flavor experience.
  • The overall output level of your device.  If you are vaping a strong nic e-liquid at a remarkably high wattage, that flavor will be stronger no matter what.  Low wattages tend to produce a slightly weaker taste, regardless of the nicotine strength of the vape juice.

Some Nicotine Has Impurities that Interfere with Flavor

One thing to keep in mind is that some low-quality nicotine may contain impurities that alter the flavor of your vape juice in a negative way.  Nicotine should be tested for purity before being added to a formula, but some companies may cut corners to save money.  Nicotine used in e-liquid is extracted from the tobacco plant, with the exception of TFN, or tobacco-free nicotine, which is synthetic nicotine made in a lab, and is not used by many companies just yet due to how new it is to the market.

Because nicotine is taken from the tobacco plant, if it’s not purified properly, it can carry some flavor molecules from the plant along with it.  This would have an effect on how your e-juice tastes, and stronger strengths would give you stronger tastes of these impurities.

Fortunately, it’s very rare for this to happen.  It would mean that you are buying extremely low-quality e-liquid from a shady company, and those companies aren’t really around as much as they were in the early days of vaping, because vapers quickly developed more demanding palates and put those companies out of business.  

Still, it is always good to make sure that the company you are buying from uses high-quality ingredients, from the nicotine to the flavoring.

E-liquids with Higher Nicotine Strengths Tend to Produce Stronger Flavor Experience

But vaping has so many variables in terms of output, coil resistance level and so on that there are many reasons why your flavor may taste stronger or weaker now and then.  Therefore, make sure you use high-quality e-liquids as this is the most important factor when it comes to enjoying a tasty vaping experience.
