Narrative:

On the last day of a 4 day trip; flts consisted of ZZZ1-ZZZ2; ZZZ2-ZZZ3; ZZZ3-ZZZ4; ZZZ4-ZZZ5. We arrived in ZZZ4 slightly behind schedule with a 32 min turn. The flight was full with a jumpseater in the cockpit. Pulling into the gate at ZZZ4 we noticed 2 management types proceeding to the jetway as it was positioning to the aircraft. Before the cockpit door was even opened; there was a knock at the door. The 2 mgrs waited for the jumpseater to leave and then both squeezed into the cockpit closing the door. They introduced themselves and dialed a number into their cell phone stating that we would have a conference call with the chief pilot in ZZZ4. The chief pilot stated that the 2 mgrs were trained evaluators and that a report had been filed with the FAA by a passenger on the ZZZ2-ZZZ3 leg that saw the first officer pour what they thought was a liquor miniature into coffee. Immediately; I could only think of getting coffee for myself and the captain at the gate in ZZZ2. I put creamers in both coffees! Apparently this is what the passenger saw. Needless to say; the evaluators judged me not impaired or under any influence. The chief pilot was satisfied; the FAA was satisfied; and the company was satisfied. I contacted the FAA office in ZZZ3; which told me that they had called the passenger back to tell him of their findings. The passenger was satisfied. When confronted with the accusation; I was very disturbed that my integrity and professionalism was at jeopardy. I wanted to immediately take drug and alcohol tests; but the company said that was not necessary and would cancel the flight. This incident caused me and the captain undue stress for the last leg from ZZZ4-ZZZ5. We proceeded to ZZZ5 without incident; but in hindsight; I feel the stress of this false accusation reduced concentration on my flying duties. This distraction was uncalled for. If a passenger feels that a safe flight is at risk; they should not have gone on the flight. They never talked to an agent; flight attendant; the captain or myself.
