You say you are an old coot - so am I - 47 years of smoking, drinking, and eating spicy food have killed my sense of taste. I kept buying e-
juice, and except for some tobacco flavorings I did not like, I could not taste a thing.
I started buying flavorings and adding to bought juices to get some flavor and by the time I got enough flavor to taste, they were so watered down there was hardly any nic left. I started DIY about a month ago. I now buy flavorings and 60mg/ml nic
juice. By the time I get enough flavor to taste I have 1/2 to 3/4th flavorings and ez-sweetz (a sweetener liquid that works with e-juice) and no added vg or pg.
Look on PA's web site, pick flavorings that she said are extra strong. Some I have had that work for me are granny smith apple, cinnamon red hots, and peach. I tried plum and watermelon and caramel candy and could not taste them even when at 2/3 rds of my mix being flavorings. English Toffee and bittersweet chocolate I have got some taste from also.
I can't hardly talk to most DIYers because they use 15% flavorings and thinks it is too much - but I can't even start to detect flavor before 50% - and since it has been months now since I quite smoking, I do not expect my taste to come back.
I have not tried much with Loranns flavorings, except when I was adding flavorings to bought e-juices - I plan to next when I run out of what I got - but will not buy from their natural line when I do since they say on there website that their natural flavorings are much weaker then there others. I did buy Flavorarts Pomegranate - 5ml, mixed it with 3ml 60mg/ml nic and could not taste a thing - but I have heard their tobacco flavors are strong. BTW - if you want sweetener buy ez-sweetz (or go to there website and they will send a free sample) - it is very concentrated. I bought sweetener from PA and from Tasty Vapor and both were so weak I could not taste it.
Hope this helps you -
