Chakotay holding a bottle of his Antarian cider
Antarian cider was a beverage, made by the Antarians, and originating from the Delta Quadrant.
Chakotay obtained several bottles of the cider in 2377, and kept them hidden aboard USS Voyager in Cargo Bay 2. When he was discovered hiding the last couple bottles by Icheb, Chakotay asked him to keep it a secret from Neelix. Icheb advised him to keep the rest in the Borg parts container, as Neelix found it to be "too creepy" to inventory. (VOY: "Shattered")
