Use precise measurements when mixing, for instance, use milliliters to maintain consistency. Begin by adding the PG and VG into your mixing bottle, securing it tightly to prevent spills. Next, incorporate nicotine. Whether you prefer a low or high concentration, always use caution as nicotine is a potent substance. It’s recommended to use gloves and protective eyewear during this step. The nicotine content varies typically between 3mg/ml to 12mg/ml, while some prefer 0mg for purely flavor enjoyment without the nicotine hit. Once the base is complete, flavoring comes into play. E-cigarette liquid flavors are wide-ranging and include options like fruity, minty, sweet, and dessert-inspired. You can even blend flavors for a unique vaping experience. Utilize flavor concentrates to avoid diluting the overall mix. Commence with small percentages, such as 5-10% of the total volume, then adjust to your taste preference. Shake the bottle thoroughly to ensure that the ingredients are well mixed. A steeping period afterwards can enhance the flavor elements considerably; this involves letting the mix rest for at least 24-48 hours in a cool, dark place. During steeping, regularly agitate the bottle to facilitate flavor fusion; longer steeping may be necessary depending on batch size and ingredient nature.
