General guidance
Florida heat and homemade soda
Warm kitchens and hot cars punish carbonation. Syrups spoil faster when left out, and a bottle that should stay sharp goes soft if it never gets cold enough.
What this climate changes
Heat drives CO2 out of solution. Serve colder than you would in a mild climate. Keep bottles out of sun and hot trunks.
Syrups
Simple syrups belong sealed and refrigerated for household use. Fruit syrups need more care — when aroma or clarity turns, discard.
Mixing
Chill the glass, chill the water or seltzer, then add syrup. Warm dilution kills fizz fast.
Not a bottling plant, not prices, not hours. Orlando Soda Company here is topic reading and inquire.
