When making a simple syrup, my ratio was four cups water to three cups sugar, what is the end volume?

I ask because i messed up a drink recipe by measuring the next step against the amount of the water and forgetting to take into account the increase in volume due to the sugar.


6 TBS (3 ounces by volume) of granulated sugar, mixed with 4 liquid ounces of water (1/2 cup US), brought to a hard boil in the microwave yielded just over 6 liquid ounces of syrup. (A drop of color added for readability)


I would suspect that it didn't reach 7 ounces because of the air included in the volumetric measurement of granulated sugar.

So 4 cups of water plus 3 cups of granulated sugar would yield just over 6 cups of syrup if not allowed to reduce on the stove.

    What will you now do with 6 fl. oz. of blue syrup? – Boris the Spider Dec 23 '14 at 8:38

    @StephenEure All of that may be true, but not what the OP asked. – Jolenealaska Dec 23 '14 at 13:15

    @StephenEure Dude..he asked for volumetric yield after volumetric measures. Mix volumetric measures of stuff, bring to boil. Measure again. Not brain surgery. – Jolenealaska Dec 23 '14 at 14:30

    @StephenEure Simple syrup is not always a 1:1 ratio, and while I agree that final volume calculation gets complex (because the crystal structure of dry sugar breaks down in solution) J's answer is definitely field-expedient. No need to turn this into a chemistry problem. – logophobe Dec 23 '14 at 16:00
