Learn Portuguese (Portugal): A gente acha que o chouriço está muito saboroso. - We informal think that the chorizo is very tasty.

The expression a gente literally translates to "the people". Because it is a singular feminine noun phrase, it requires the third-person singular verb form (acha). Even though it means "we" in casual conversation, the grammar strictly follows the singular noun.

Could I say nós achamos instead of a gente acha?

Yes, absolutely! Nós achamos is the standard way to say "we think" and is safe for any situation. A gente acha is a very common, informal alternative used mainly in everyday spoken Portuguese.

Why use acha for "think" here instead of pensa?

In Portuguese, achar is used when expressing a personal opinion or assessment (similar to saying "we find the chorizo tasty"). Pensar is used for the literal cognitive action of thinking or pondering something in your head.

Why does the sentence use está instead of é for the chorizo being tasty?

Using the temporary verb estar (está) means you are talking about the taste of this specific piece or batch of chorizo right now. If you used the permanent verb ser (é), it would change the meaning to a general statement like "chorizo is a very tasty food".
