Hi Rosa. Nice song. Amusing video - it gives me a new angle on "comparsa". :)

A couple of points about the English:

1st stanza 3rd verse: I think you intend "by" as part of the phrasal verb "go by"? If so, you need to follow it with a comma to prevent "by filling...." being read as an adverb phrase indicating the means of going. But I can't see any reason for not just saying "we fill...." other than perhaps to up the syllable count in the line.

2nd stanza first verse: it's more nomal to say "bathe...in" or "water...with" than "bathe...with" unless talking of treating a lesion with a topical antibiotic or analgesic. (yes, I know some people consider red wine as an analgesic, but surely an internal one not a topical one unless it's really awful wine :) )

3rd stanza 1st verse: "Por que" is more "Why should" than "How could", maybe?
2nd verse: missing "does" after second "why", and "wonders" should lose its "s".
4th verse: needs "do" after second "why".

4th stanza (missing space line before)
verses 1 to 4: "would" doesn't present a hypothesis to test, it introduces a condition; here you need "could".
verse 1: "of your beautiful women" is pretty low register: you could say "on account of ... ", which is a higher register equivalent, but I think that "your women are beautiful" would be betterthat any "because of" or "onm account of" version.
verse 2: you need to swap "your" and "the" - as it stands, you're saying that wine cheers Portugal's heart instead of that Portugal's wine cheers everyone's heart.
verse 3: because can't be followed by a noun phrase, it needs either a clause or "of" followed by a noun phrase (but see comment on verse 1); what is wrong with "your roses smell wonderful" or something like that?

The rest is repeats, so the comments above apply to them too.

Kind Regards

Tom
