Why do some name brand items taste differently than off-brand items, yet they have the same ingredients?

Answer 1

Mostly same ingredients in different amounts, different packaging techniques/environments, different base ingredient purity and quality.

But also potentially a psychological element. There is a chance that if you took one product, split it in half, and told someone that one half was a certain brand (say one they’re familiar with) and the other was a different brand, they may tell you they taste different.
