![]() This is especially the case if the flavour contains nicotine. The colour of the liquid can also be an indicator if a flavour needs to be steeped or not. If a flavour has any distinct chemical tastes, harshness or a flavour that shouldn’t be overpowering that seems to be overpowering the flavour, it is generally a good indicator that the flavour can yield benefits from steeping as these properties can be removed from steeping the flavour. Ultimately, if you like the taste of a flavour and notice no off notes, its well rounded enough and good to vape. If a flavour has a harsh or chemical taste, these can generally be eliminated by steeping for longer. Flavours with a higher VG percentage can take longer to steep as VG has a higher viscocity than PG, therefore it takes longer for flavours to mix together due to the denser, thicker liquid. General rule of thumb though is the more concentrates used in an e-liquid the longer it will take to steep as more flavours need to homogenise. There is no real science behind this as there are several factors at play, it really boils down to testing to determine what really works. Flavours with spices, tea’s and other similar notes can take longer to blend as well. On the flip side, some premium e-liquids do not come pre-steeped and these e-liquids can have a higher amount of concentrates used in the liquid, which means it needs more time for the flavours to blend together.Ĭreamy flavours have a tendency to require a longer a steeping time, while fruity flavours tend to steep quicker but have a higher amount of initial overpowering sharp notes. Some premium e-liquids come pre-steeped and this is what can warrant such a high price tag on many premium flavours as you can vape them right away and can enjoy them at an optimum taste point. There are a few general rules you can follow to help you to determine which flavours need to steep and for how long. It is always best to apply as much science and testing behind steeping as possible and this is why streathing is an important part of the process. Some flavours won’t change at all or change by only a small degree and these are often referred to as shake and vape e-liquids.ĭue to the vast amount of different flavours on the market it can be difficult to determine which flavours need to be steeped and how long you should steep them for. The degree at which the colour changes in your e-liquid is dependent on the presence of nicotine and concentrates with colourisation. Due to this, it takes a longer period of time to reach the full desired flavour and colour. The Mailard reaction gets exponentially slower as it progresses and this is why when e-liquid first starts to steep you see the golden and browning colour forming over a few days while the colour darkening slows the longer you let it steep. It is due to The Maillard reaction that the fastest method of steeping is hot water bathing your e-liquid as this accelerates the process. The Maillard reaction also occurs at a slower rate at lower temperatures such as the aging of wine and balsamic vinegar. ![]() A high temperature example is the change of taste and browning of potato chips as you cook them. The Mailard reaction is accelerated at higher temperatures. The change of colour and taste over time is caused by a chemical reaction between amino acids and reducing sugars. Even after shaking, the liquid will need too steep for all the ingredients to homogenize and become uniform Due to this, shaking your bottle after mixing is necessary. ![]() ![]() VG has a higher viscosity to PG which means it is thicker in texture and more easily sinks to the bottom of the bottle. When mixing e-liquid, the different components and ingredients have varying levels of density and thickness. Steeping helps reduce or remove off-notes, chemical tastes, harshness and balances out flavours. Allowing a bottle of e-liquid to steep helps evaporate, chemically breakdown and infuse the flavourings, PG, VG and nicotine in order to enhance the taste. The process of steeping e-liquids is similar to the process of aging wine in order to produce an improved flavour. Steeping allows the VG (vegetable glycerine), PG (proplylene glycol) and flavour concentrates to homogenise into a uniform mix. Steeping refers to the method used to improve the flavour of e-liquid through a process in which you allow the e-liquid to mature. ![]()
