Here are some notes on a few of the flavors I'm trying. I've got a fair amount to go yet, no free samples for me, paid for them all.
Honey
@2% strong smell, taste is pretty good
@3% stronger smell, taste is still pretty good, close to stand-alone flavor
@5% tastes pretty darn good on its own
Color starts @1%, 3% light amber hue
may be a winner to mix with Tab
This is a strong, but good Honey, very noticeable @2%
Dutch Apple Pie
1% slight apple scent and taste
3% slightly stronger, good starter for background note
5% starting to take form as a noticeable apple pie flavor.
7% this is about where you'd want it for strong secondary note or people who prefer light taste
9% Light but good apple flavor, pie crust undertone, a bit light for stand-alone
10% nice flavor, a bit light, probably where a lot will like it for standalone, or secondary
12% starting to show color.nice pie smell, little light yet on flavor
14% Pretty good, maybe just a bit more for stand-alone
15% is pretty good, and very close for me as a stand-alone
16% apple is starting to hit harder, not bad at all, maybe on the edge of to much.
17% additional flavor did not do much I think 16% is about max
Flavor seems to be a dirty burner/gunk coil. It needs something else to make it pop
Has a very nice smell.
Cappuccino
1% weak sauce! very slight sweetness, and taste, maybe a good BG note
2% Where are you?
3% Hmmm
5% weak but starting to show.
7% still weak, not much at all, needs steep time?
9% very light but just a bit here.
10% little change, slightly more sweetness
12% nope
14% starting to show, OK cappuccino, but pretty weak.
15% is pretty decent, a little weak, but not bad, flavor is OK, I've had better.
Overall, this is a pretty high % to get the flavor, and it is not much on its own. I'm used to other Cappuccino's that are much more potent
Salted Caramel
Not many notes on this one, a good flavor though.
13-18 % as a stand alone, start at about 5% for a background note.
Flavors are definitely subjective, and these are just my experience. Will add more as I have time to try them.
