PHP/mySQL question about groups

Let's say I have a PHP-based wine application, and it's taking a set of mySQL data that looks like this: wineid name size 123 Silver Oak 750ML 123 Silver Oak 1.5L 123 Silver Oak 1.5L 456 Liberty School 750ML 456 Liberty School 750ML 456 Liberty School 750ML 456 Liberty School 1.5L If I do a: Select * from wine where name = 'Silver Oak' GROUP BY 'wineid' I'd get: Silver Oak However, what I'd REALLY like to return is: Silver Oak 750ML Silver Oak 1.5L I'd like the groupby to group by wineid, BUT ALSO separate the groups by 'size'. So there'd be a '750ML' group, and a '1.5L' group Can anyone tell me how I'd do that? I'm hoping I don't have to write a PHP script that loops through the results and separates things manually.
