I’m a container, but if you reverse me, I talk a lot about nothing.

I stand in place, firm and tall, sometimes a fence, or a wall. I keep apart what shouldn’t meet, yet let the cautious pass discrete.

A savory bottle from town With a name that can make a man frown Though the letters are plenty The sounds are but twenty Its the trickiest sauce to gulp down

I have a thousand keys, but I cannot open a single door. I can give you a space, but I have no room. I can allow you to enter, but you can never leave.

I serve one of the five senses, Two dark tunnels run through me, giving passage to fair friends and foul enemies, I am a special comrade to perfumers and canines
