Absolutely!! letting certain juices steep will defiantly bring out or settle flavor. Depending on the vendor and order, your juice was either mixed right before it was sent out. Or it has been sitting on a shelf for a while. You can defiantly tell when you vape outta the box, which is fresh and which has been hanging out. I have had flavors that were too intense with sharp, chemy tastes. Come back to them 2 weeks later and they have smoothed out, and the flavor had exploded.Other times flavors were way to strong. Gave them time and they mellowed out. Opening the bottle will just speed up the process a little. Keep them open for a couple days then seal them up and forget about them. Come back in a week or two to a wonderful surprise.
Its pretty obvious that fresh juices need to settle. You have never gotten a juice that changed color? I got some samples last week that were completely clear when i got them. Now some have a pink or yellow tint to them. One is straight up orange! When this happens you know you are getting a fresh mix.
Quote from a favorite supplier that comes with ever order.
" Nicotine,flavors and bases are all within expiration dates of one year. Liquids may last longer, but the nicotine strength will start to degrade at that point. For maximum freshness, we suggest you use your products within 6 months.
Color change is normal in many liquids. Many start out clear and will turn brownish or orangey in the weeks following mixture.
Flavors may intensify or mellow over time, coming into final flavor in 1 to 2 weeks."
