I have used FlavourArt before, but I never used bacon.
But, it is almost the same with most of the flavors from FlavourArt. If you use too much flavor, it tasts terrible, and they (FlavourArt) state that on their Web site.
I went into the same trouble before when I used FlavourArt for the first time. I used the Calculator, and it was set already on 20%, then I used 10% and then 5%, and still tasts bad and also it did not taste or smell as the original flavor.
Well, it is very simple. Use 1% to 2%, and that's it. Let it sit for a little bit, 15 minutes, and it tastes wonderful. The next day, it would taste better.
What I have done, is reuse the calculator to thin the liquids I made already. If you need help, I will explain in more detail.
But, the key with FlavourArt is 1% - 3%. Start with 1% always. (This is how they recommend it on thier Web site).
