When you say in general that something is good, use bom either for masculine or feminine words, or even verbs. Ex: manteiga é bom, vinho é bom, andar de bicicleta é bom. If you are specific, then you change the adjective: ESSA manteiga é boa.
Right! But if you use articles, then you must use the feminine boa.
Manteiga é bom
A manteiga é boA
