Here are my standard NN recipes, all 30ml bottles. Flavors are measured using drops from a glass dropper (31 drops/ml is what I've found to be average for the flavors). Ratios are pg/vg.
I've been making these like this for a couple months and feel like I have found the sweet spot for me at the following concentrations:
Tobacco - 60/40, 8mg Nic, .75% flavor
Citrus Slap - 50/50, 4mg, 2.5% flavor
Apple Pie - 50/50, 4mg, 3.5% flavor
Shirley Temple - 50/50, 4mg, 3.5% flavor (read that it's a tank cracker but I haven't had that issue at this %)
Very Berry - 50/50, 4mg, 5% flavor (may try 6% sometime)
Strawberry Kiwi - 50/50, 4mg, 5% flavor (may try 6% sometime)
I just got these in a couple days ago. I just mixed up some "standard" test concentrations to try and create a baseline for concentrations. Test bottles are all 17ml, 3.6mg Nic, 50/50 and 3% flavor. All were sampled within a day or so, with no steeping, since I'm trying to get a taste of the juices as they are initially.
Minty Menthol - Used at 1% as a mixer with Patchouli Vanilla and Melon Madness. Has a great "natural", bright flavor, mostly spearmint for me.
Mayan Mocha - Really great. It's not very sweet, not like coffee or milk chocolate. I tastes like cocoa and spices, exactly like the Mexican hot chocolate I tasted back in spanish class in middle school.
Guava Papaya - It's ok, not what I was hoping for (I love MBV's Guava). I think the % is close to where it needs to be but it needs more time.
Coffee & Creme - Pretty good, I looking forward to seeing what 4% tastes like and I plan on blending with other flavors.
Peaches & Creme - Good peach flavor, light, clear and subtle at 3%. Interested to see if the flavor deepens.
Patchouli Vanilla - I haven't tried it straight yet but I did make a Patchouli Vanilla Mint and it shows lots of promise. It's not a thick, sweet vanilla, definitely light with a pleasant vapor smell. edit: I just tried it and it either needs a lot more time or more flavor. The mint one is better at this point. I think it could be a good one if I can figure it out.
Banana Creme Pie - Tastes great at 3%, I would even try it at 2.5% next time. Nice Banana flavor, not sure the pie part is very prominate. Maybe it will come out over time.
Melon Madness - Not real sure about this one, almost nothing there. Definitely needs more flavor (5%?) I made a "Watermelon Mint" by mixing this with the Minty Menthol. I still need to work on this one.
Passion Fruit Coconut Creme - I ordered this thinking maybe it would be something like a Pina Colada flavor, but it's not. At All. I don't even know what passion fruit tastes like so... this tastes like a weird hard candy? My wife loved it though, so it's got that going for it.
