Why change something from good to terrible

I started buying c***** creamel last year and enjoying it with my coffee until I ran out this month and found the the 1 with a new improved recipe. I don't know why change it. The new improved recipe tastes terrible, it has a bitter after taste and have to try finishing because I don't want to waste my money. But honestly I regret buying it because I honestly don't have the luxury of money to waste.
