FLV Root Beer: This Root Beer nails all the top notes just perfectly. A perfect blend of wintergreen, anise, and hints of sarsaparilla. It's a bit thin tasting, so it needs a little help with depth. We get that much needed help from FLV Vanilla Bean and FLV Caramel.
FLV Vanilla Bean: This has some elements similar to FLV Cream, but a bit more tame and a lot less dairy. Those dairy notes are replaced by a soft vanilla overtone that shows up just enough to keep the root beer authentic.
FLV Caramel: Our dark, syrupy sweetness. We don't need much here, at .5% it barely shows through at all. Lower than .25% it wasn't present enough, and at .5% it's almost too much. Wanting to balance the higher % of caramel, I added a tiny bit of FLV Lime to brighten up the back end and finish the recipe.
FLV Lime: It took just a few drops to turn this around and make a perfect bright soda finish.
FLV Ginger: My first test at .25% this didn't show up quite enough. .75% was too high for my taste and it started to wash out the more delicate notes in the Root Beer. Dialed back to .4% it seems to sit just right. Present, but not overly so.
I may come back and tinker with this, but I'm pretty happy with where it is right now.
