I am a teacher and sometimes I will brew a cup or two in my room.  My students have more than once commented that my room smells like tuna.  I didn't realize it at first, but now I can see what they mean. Has this happened to anyone else? Am I roasting something incorrectly?

OK, I'll "bite":
Do you live near the ocean?
I lived in Miami for 21 years, and you could smell sea air 15 miles from the beach.

You're not crazy IMO, and I doubt it's the sea air. ;)

I've noticed this before and posted about it elsewhere, though I thought the odor was more noticeable with a particular dark roast and with slightly stale, unbrewed coffee grounds. Back when I would drink this coffee--warning, potential TMI---I thought it made my urine smell like tuna as well. Sorry. ;0 Several years later I caught a whiff of whatever compound is responsible for the tuna effect when I opened a can of chicken breast packed in water (for lazy man's chicken salad). So, it's something meaty in a way I have trouble verbalizing.

Here's another tuna report: Click Here (www.smellingthecoffee.com)

And another (well, the same thing crossposted, but check out the comments!): http://www.jacobgrier.com/blog/archives/695.html

I've smelled the tuna coffee as well, more than once. I think it was Peet's coffee. I didn't notice it in my urine.

Maybe it will become the next new thing: The tuna bomb?

I saw those articles while looking around the web.  I can't figure out what I'm doing to get that smell.  One person mentioned rancid oils being a possibility.  I use a plastic melita single cup brewer. I wonder if that has something to do with it.  

This has been with fresh roasted coffee. A couple of different types at different roast levels.  I don't notice it at home so I guess it has to be the plastic cone, or maybe a combination of smells in my classroom.  I teach science, so there are sometimes an interesting combinations of smells anyway.
