Because the Mix between water and coke syrup is different. I don't think it tastes better thoughLike the Coke at McDonald's taste better then a can of Coke
That sh1t don't even make sense how McDonald's gon murder Coke on their own sh1t???
How do I buy a 2 liter of McDonald's Coke????
She doin heroin in this clip brehI prefer pure columbian
Everyone above is wrong
Real answer:
Because they sell a lot it doesn't sit around as long. So the Coke syrup at McDonald's is fresher than their competitors. Fresher syrup makes better tasting fountain drinks. McDonald's also controls freshness by cleaning everything daily.
You'll notice soda at pizza places are a lot better for this same reason
Fountain drinks areSyrup, probably better ratio of water to syrup compared to the bottlers who get more money by stretching their syrup out.
Sometimes though they get better recipies at the fast food places. I cant drink Sierra Mist no more because I hate the taste of the real sugar ones they sell in the store and to canners and bottlers, but Taco Bell still has the corn syrup formula at the fountain and it takes so much better
