I'll start at the beginning. I heated up 1.5 gallons of water just hot enough to dissolve 4 pounds of sugar. I let that cool down while I sanitized my equipment. Then I mixed the sugar water with 3.5 gallons of water from the refrigerator. It wasn't cold but definitely wasn't hot. Kind of semi-warm, I guess. I pitched the yeast on the mixture and stirred it in. I bottled in 2-litre bottles. Now I'm starting to worry if the mixture was too hot for the yeast and if I pitched incorrectly, if that's possible. Sorry for the noob post. I've never made soda before.
