Should a syrup sample be approved from a water test?

No. Water can be a screening step. Final approval should use the real coffee, tea, soda, fruit or other beverage base and the intended serving conditions.

Which physical checks matter first?

Use the checks that match the application: Brix or solids, pH, viscosity, pour or pump behavior, clarity, sediment, separation, crystallization, color and foam.

Does a day-zero taste test prove shelf life?

No. Repeat the agreed physical and sensory checks in the intended package and storage conditions before making a shelf-life decision.

What information helps a supplier prepare the right syrup sample?

Send target market, product type, packaging specification, estimated quantity, required certificates/documents and whether samples are needed, plus the real base and process.
