My experience has been that the true test of a brand is whether a loyal customer can identify the brand in a blind test.
I have carried out many such blind tests over the last decade or so and have found that a significant number of brands fail that test. I have no clue about krbl products though but the base rate i can say for sure is not too high. One interesting thing that never fails to occur is that the more enthusiastic the customer is about the brand the more prone he or she is to fail the blind tests. Just sharing as i thought it may be relevant here.
