Looking for a cheap replacement for White Claw Surf Pack

The White Claw Surf Pack have been my favorite drinks lately, but rising prices have made it so I can’t really justify buying them anymore.

If you haven’t tried the Surf Pack, they’re different from regular White Claws in that they’re vodka based and taste way sweeter and pretty sour.

I’ve found that vodka in a Bubly tastes similar to a regular White Claw, but I’m not sure how to recreate the sourness of the Surf pack. Does anyone have any ideas?
