Should the control be included in every first-round test?

Usually yes. An existing or sucrose control gives the team a reference for sweetness timing, acid balance, body and finish.

Are four samples enough to approve a formula?

No. Four samples can answer a first comparison question. Production, packaging, storage, documents and target-market checks still need follow-up.

Which time points should be used?

Use consistent points that match the beverage. Initial, peak, 30 seconds and 90 seconds are a practical starting set, not a universal rule.

Can this scorecard be used for an erythritol-free system?

Yes. Mark erythritol-free as a project constraint and record the body, sweetness and finish trade-offs in the actual beverage.
