What sort of traps would Kobolds set up around a brewery? (new DM)

I recently got some superb advice here on making a fun brewery adventure, and I had a few more questions for the more experienced DMs out there. To reiterate, I am DMing a group of lvl 3 characters for only 1-2 sessions so I can learn the ropes, and I would like to include some fun traps they need to look out for. I'd love to also make sure that everyone gets a chance to contribute, and not just have the rogue (our most experienced player) do all the detection and disarming.

What sort of things would be fun to set up so that players would all need to watch their step, but could also contribute a bit?

Party has a bard, ranger, druid, and rogue.
