Capitalization

Which is correct? (capitalization)

1) I do not like Tropicana orange juice.
or
2) I do not like Tropicana Orange Juice.

This, too, could go either way. I probably would not capitalize it. Of course, if I abbreviated it, it would be OJ.

On the packaging, they seem to just use Tropicana, with the type of juice displayed elsewhere, so I would probably use lower case as it's not part of the name.

Does it really matter?;-)
