In how much joose?
In my experiences, it's not so much 'bout tang as a slight enhancement in da flav(s). When I first started using LJ and ACV, I was using 1 drop/3ml; some folk use more.
Also, 'drop' is a relative term. Just keep track of how many you're using in any given recipe.
Good luck and please let us know your results!
I used 1 drop per 5 ml of juice. I like the flavor better this morning. Of course it's always better in the morning, before I assault my tongue with all these wonderful and different flavors.

I might still increase the lemon juice, though, just as an experiment, to see how it turns out.
Well that ain't nice ... telling us you got something new but not what it is. Now you'll have to post pictures when you get 'em.
Also ... please make sure you're using quality batteries particularly if you're building sub-ohm coils.
I was gonna answer, but I see Rich already did.

As for the batteries, I think we have good ones. Samsung 25-somethings... oh hell, Rich is the battery guy, he knows what we have. Anyway, a couple other ECF battery experts also recommended them, so I think we're OK there.
Lannie,
It seems to me that fruit flavors often suffer from flavor loss over time. I've started making smaller batches so they stay fresh, plus it gives me an excuse to go into mad chemist mode and DIY.
I also find that flavors taste different depending on the power. I have one that if I vape it lower power, I get more of the ice cream flavor but if I crank it up I get more of the Irish Cream/Kahlua zing. Sometimes it's just fun to play.
That's the truth! I love coming up with new creations in the kitchen (when I have the time to play!), and this is just as much fun, if not MORE fun, because a bottle of juice lasts longer than dinner. Also, I've been keeping notes on the juice that I make, so unlike dinners, if I make something really good, it's written down and I can duplicate it later. Sometimes I make the absolute best thing for dinner, but it's a one-shot thing because I didn't watch what I was doing and forgot what I put in it!
I read on the Flavor Apprentice thread that sometimes a very low percentage of raspberry can make other fruit flavors pop. Very small %, not enough to add flavor, just to make flavors pop. No personal experience yet, so just passing on what I read (on the internet no less!, but BillsMagicVapor is a quite talented mixologist).
Oh, YES, I'd heard that before about the raspberry as well, and totally forgot! So far, the CAP Sweet Strawberry has no problems with fading, at least in my opinion, but maybe a little touch of raspberry would go good with other flavors. There's already raspberry in this Harvest Berry flavor - I believe it's strawberry, raspberry, blueberry, and blackberry (if you go by the picture on the bottle). I can taste the blackberry most of all, then the blueberry, and the red berries are way in the background, undetectable as their own flavors, but adding to the whole mix. However, maybe a bit more raspberry would help. I think I might already have a bottle of that, but if not, I'll get one and try it out.
You know what I think this berry cheesecake REALLY needs, though, is a bit of added graham cracker flavor. It's there in the cheesecake, but it's very subtle, and (bear with me while I try to put this into words) it seems like the berry flavor and the cheesecake flavor are blurring together too much. It's very soft and it tastes very good, but it's almost TOO soft. It would be good for beddy-bye time, you know? But a touch more graham cracker would put a sharper dividing line between the two flavors, and make it seem more like a real piece of cheesecake with berries on top. Since I really love this flavor, I'll make two bottles next time, one with a little extra raspberry, and one with a little extra graham cracker, and see which one I like better.

It's not like I won't use 'em both up, right? LOL!
