I believe that, if you are from Portugal, you can just say
"Portuguese". Brazil was colonized by Portugal so that's why we speak
Portuguese in Brazil. I'm Brazilian and I always emphasize that I
speak "Brazilian Portuguese"
I'm a little bit curious about what you said @heMarceloR, because I'm Brazilian and I've never had to say "Brazilian Portuguese" to someone, actually, when you are filling your profile in some website, 99% of the cases you see something like: Portuguese | Portugal Portuguese. A good example of that is the Google translator, is there a way to set the Portuguese from Portugal? I don't think so. Given that, when someone says "Portuguese", most of the people are going to associate it with Brazil. I don't know why you've put the "colonized" matter in your response, it's like comparing England with US. When someone says: I speak English, you will associate it with the US, and it's ok.
Answering the question, you can say: Europen Portuguese or Portugal Portuguese. If you want to say Portuguese from Brazil, you can just say: Portuguese.
