Looking for Seltzer recommendations

Hi! I’m not a big beer/seltzer drinker, however, I recently stumbled upon these and I absolutely love them! The flavor is boysenberry and vanilla. I feel like the texture is a little different from normal seltzers; being a lot thicker and foamier. The flavor is also pretty sweet and almost a bit tart. I’m curious if anyone has tried these before and knows of any similar drinks that have that same texture and flavor profile. Thanks in advance!
