I was excited to crack open a nice cold soda and burp for you. Come to find out, i hadnt stocked the fridge so all i had to work with was warm soda. The difference in temps make them quite different. Fizzy and kinda spicy burps fall out. With almost each sip, i roar out belches, loud and in charge. I do have a burp stuck pretty deep. What do you prefer? Warm or cold?
