2. John ran as fast as, or even faster than, Paul

i thought both of them are correct.. but latter one is correct and former one is wrong

comparison confuses me always.. kindly help!

1. French wines taste better than American wines

[David L.]

Who told you it was incorrect? You are understandably going to be confused if some book or friend is giving you wrong advice.

[tedtmc]

It could have been an American who thinks that American wines taste better than French wines.
Otherwise, there is nothing wrong with the sentence.

[kiranlegend]

what about the second sentence?

[tedtmc]

John ran as fast as, or even faster than(,) Paul

The sentence is fine, 2nd comma not required.

[David L.]

It would be better as:
John ran as fast as, and even faster than Paul.

There may be some question, or context or other where 'as fast as, or even faster' would be a suitable reply/response; but as it stands, 'and' makes more sense.
