I can't remember which building produced these on top of my head, but if you hover over the small "!" sign at the right of the quest requirements, it should tell you which building produces the required elements.
As gimccla said, the Sailmaker creates the Streamers at five minutes each.
That's 20 minutes if you have the sailmaker already built. I'm not sure of the timing for the beer (have already torn down the building for that), but pretty sure the kegs are at least an hour run each.
