Why is this sqlite3 UPDATE giving a syntax error?

I have a function that drops some tables and reinitializes a new set which are working fine, then when it updates the existing table with the following:

self.cursor.execute('''UPDATE beers1 SET (beer_name, og, fg, beer_desc, ibu, glass_type, keg_size) 
    VALUES (?,?,?,?,?,?,?) where id=1''',("Beer", 1, 1, "Delicious!", 0, "Pint Glass", 640))

Which then gives me:

OperationalError: near "(": syntax error

Any insight would be incredibly helpful. Thanks!
