Question

The recipe goes on to tell you that for best flavor , the 40% tequila (80 proof) must be diluted to a final concentration of 5%. You want to mix the 600 ml of smilple syrup, 250 ml of lime jucie and enough ice to a total margarita volume of 1800 ml.

How much tequila will you need to add to your recipe ?

Answer 1

Total Volume of margarita= 1800 ml

V_syrup= 600 ml

V_lime= 250 ml

Total Volume of Margarita = V_syrup+ V_lime+ V_5%tequila (Assume volume of ice as negligible)

1800 = 600+250+V_5%tequila

V_5%tequila = 950 ml

Now, make alcohol balance since alcohol content is same before and after dilution.

0.05* V5%tequila =  0.40 * X   

Where X is volume of tequila before dilution

0.05*950 = 0.40*X   

X= (0.05*950)/0.40 = 118.75 ml

So, 118.75 ml of 40% tequila (80 proof) needs to be added to the recipe for best flavour.
