I've got 25'+ of duct to run to exhaust outside the house.

An option(?), I can run duct 3' horizontal and 3' down from my hood and be at the bottom of my utility sink.

Anyone care to comment on whether this is a viable option?

Sounds like you got lost if you wanted to go outside, but ended up under your sink.

I'm confused too. Are you saying either:
a) Discharge it under you utility sink - I think this would end up with a lot of moisture in this area
b) Discharge it into your utility sink's drain pipe - could have issues if you a using the drain for water at the same time, resticted flow to the sewer and smells/gas coming up from the sewer (exploding toilet anyone?)
c) Cut a hole in the wall behind your utility sink and vent it outside down low - no big issue just make sure the grate would allow anything to crawl back up and build a nest in there.

Rereading your post it sounds liek option b but not actually tied into the drain pipe, I would think you would end up with a little bit of each negatives from a & b.

Your option "b)" is what I was aiming for, mattd2.

I was hoping I could just connect an inline duct fan to the hood with a flexible dryer vent to push the condensation into the utility sink. Something that could be taken down and put out of the way after boiling.

Attached is a crude drawing of what I was thinking.

If this is inside you probably want the hood to vent outside due to carbon monoxide, not only a moisture issue.

Sorry for not mentioning earlier, but this is for an electric brewing setup, not propane.

Good point, are you using gas or electric? Edit:Never mind, I type too slow!
I would think you would want to actually "connect" the duct to the sinks drain hole. That way you would be forcing the discharge down the drain and into the sewer (as long as there is not too much back pressure). Then just run the tap afterwards to fill the s-pipe up again.

Ejecting the exhaust fan into a drain won't work. You really need to get it run outside with a duct run the will move the appropriate amount of air. Your talking about a lot of moisture from each brew session building up in your house. If you don't want mold you need to exhaust enough air outdoors.
