Pink Label in 50PG takes 2 months to steep for me. Set it aside for a long steep and then it will lose the tartness and really come together. It may take longer with 100VG. But if it turns out that you just don't like berry mixes then it probably won't ever work for you.
I wonder if it is the berry mixes that you don't care for? Maybe try something with a single berry like Strawberry Vanilla Cake, Strawberry Shortcake, or Blueberry Vanilla Cake. Rumor is that there is a Lemon Vanilla Cake that you can try to request as a sample. I'm dying to try that one! It would be interesting to see if you like an individual berry flavor.
Pineapple Cream is really good! So is lemon and lime. None of them are tart and the only one I like sweetened is the Pineapple Cream. I figured I would like the lime and lemon both sweetened since that's how I love the pineapple but they were too sweet and ruined the taste for me. The pineapple is a bit different from the others since it started as a pineapple ice cream flavor they were making.
Make sure to reply to the feedback email or use the contact us form to ask for more pineapple. It needs to be added to your profile before placing the order.
Yeah I plan on setting the pink label aside for quite a while before giving it another try. Blueberry Vanilla Cake is going to be the next flavor of theirs that I try. I haven't tried any blueberry flavors yet so I'm looking forward to seeing how it tastes. Plus, they have it as an express item so I can try vaping out of the box. I look forward to reporting back on my next order. Ahlusion has been great so far. Seriously, this company is all about making the customer happy.
One other thing I was thinking about....before I ask them to adjust the pineapple flavor in the pineapple usd cake, I might want to wait and try the flavor in a carto tank. I should be getting my new IBTanked setup in this next week so I might hold off and test my current batch in the new tank before I contact them. I've read that their juices are designed specifically for drippers. I'm definitely going to let them know in my feedback email what type of tank setup I'm using and see if that makes a difference.
