Brewing my own drinks?

So i was thinking about how many drink companies are kinda horrible, this was mainly brought to my mind because i enjoy a crisp energy drink every now and then, but my preferred drink is partially owned by coca cola, so i don't really fuck with that, so i was thinking "can i make my own delicious caffeinated health hazard?" probably yes!

I'm a bit of a chemistry nerd, and my entire family has dabbled in alcohol brewing before, and i genuinely mean everyone. Making an energy drink can't be that difficult, right? It's just sugar and artificial flavors + caffeine and some funny alchemy stuff. 

Could i technically invent my own? 

I like designing stuff so i totally could make a design for an energy drink :0 ALSO i really want it to be in a glass bottle (mostly because idk how to can a drink yet)

Also i could have different levels of caffeine, like how beer and stuff has different levels of alcohol like 4,6 and 5,5 and of course my preferred 8,0

I need to get into drink mixing, my dad was really good at it, and i believe i could be as well, i did make a gonster (guiness beer + monster energy) a few months back and i enjoyed it, like the heathen i am. (PSA, DON'T MIX ALCOHOL AND ENERGY DRINKS) I usually don't really dilute what i drink, i usually just get the strongest beer or a bottle of 20% flavored vodka and just drink from the bottle (this is once a year, usually i just chill)

This is just my excuse to get back into chemistry, i loved it so much omg, was sorta good at it too :')

I'm just wizard pilled lmao, brewing potions and smoking herbs, all i'm missing is the hat and robe :D
