Difference between Picon Amer, Picon à l’orange, Picon apéritif

Hi everyone,

I’ve noticed three different kinds of Picon at my local supermarket: – Picon Amer – Picon à l’orange – Picon apéritif

I’ve also come across Picon au citron, which I assume is similar to Picon à l’orange but with lemon instead of orange.

Could someone explain the differences between these three main types? And which one is best suited for mixing with beer?

Thanks in advance for your insights!
