Measuring Soft Drinks Sugar Content /// Again!

Are you still interested in measuring soft drink sugar content and visualize it into tablespoons? I started a post about these on year 2010 but unable to continue due to unavailability of refractometer – a simple hand-held instrument use to measure sugar content. The instrument is within my reach again and I am thinking if I am going to continue my halted activity.

After a quick conversion (for the Cobra only), I arrived at sugar content of 43.2 grams or 3 1/2 tablespoon. However, the bottle label was telling the otherwise. The total carbohydrate it contain was 39 grams. A 4.2 grams difference. Note that this reading was made on year 2010.

Were my very own readings more precise and accurate? I think I need more research about refractometer, degree brix and soluble solids.

I think it is still worth the effort… I am going to do measurement as popular beverages cross my hand.
