numerous tmidis and 100% supervised sounds complicated to me. plants with numerous ingredients are not that complicated to supervise if you have a proper system in place. Ensuring no goy touches anything from pressing till bottling (or more accurately cooking/pasteurizing) is complicated. That's besides the kulos that may be relied upon.
This is the reality not perception.
Again, can you point to specific Kula that OU relies upon?
Of course it’s complicated, but what makes you say the OU relies on Kulos in this case?
Sounds like you’re saying “the OU is not a heimish hecsher so they must be using kilos”.
