For no particular reason, years ago I stopped drinking coffee very much and maybe have a cup once every two months or so, tops.
Today I walked down the grocery store aisle that had coffee beans, and wow - did that smell great!
Didn’t buy any, but sure did smell good.
I really like the smell of egg nog, but the texture is so thick that it doesn’t appeal to me very much. I could sniff it all day, though. 
Custard.
Never been a custard person.
Herbal teas smell lovely. They just taste like hot water to me though.
My sister makes this quiche that really smells great, but I can’t stand the texture and consistency when I’m eating it.
Pipe tobacco smoke, wonderful smell but awful taste
Gasoline.
Coffee, pipe tobacco when it’s not burning, apple pie, all of my attempts (so far) at curry.
Vanilla extract; spoken from childhood experience.
What’da I win?
Coffee. I don’t mind the smell of it, but can’t stand the taste (and I know that coffee’s taste is 90% smell).
DAMNIT!
Once, my dog was really bugging me about it. I mean jumping up and down, barking, begging for it. So I let him lick the spoon after I had poured it out.
Wow, that dog got cured of begging fast.
Rum thins it out nicely.
Snausages and Beggin’ Strips.
Liver and onions. It smelled so good I was dying to taste it. I couldn’t even swallow it and almost puked at the table. Blech.
Liver and onions, coffee and red wine. When I was a young meat-eater, I would get tricked into trying liver and onions at least once a year because of the smell alone. I just couldn’t believe that something that smelled so wonderful tasted so rank!
Anything from a fast-food joint. Smells great, tastes like cardboard.
You and Shayna posted exactly what I wanted to post, but didn’t feel like posting from my slow ass phone. I knew by the time I got to my pc, someone would have had posted it.
The only difference is, I actually started to love it all of a sudden, right when I was about 18, for some mysterious reason.
Then, I stopped eating meat all together about 6 months later, so that gave me about a 6 month window of actually liking liver and onions, which I am sure is 6 months longer than most folks.
Bisque smells awesome, but the taste is a little incongruent and slightly sweet & bitter. It tastes good, just not as good as it would belie.
Perfume…smells great, tastes awful.
Crayola scented markers… mmmm…
Vanilla extract has already been mentioned, I know, but it reminds me of the day my father showed me as a young tyke that a touch of vanilla extract dropped onto a spoonful of brown sugar is absolutely delicious and is a rather close approximation for the flavor of cookie dough. It was important, however, to only enjoy this treat when mom wasn’t home.
I also second pipe tobacco. When I was little I had a great uncle who smoked a pipe. I would park myself on his lap and just breathe in the sweet aroma whenever he visited. It’s a wonder I didn’t develop childhood cancer.
Peanut butter cookies also smell much better than they taste. I love peanuts and peanut butter, so the smell of peanut butter cookies makes my mouth water, but I’ve never actually liked them.
Oh, and, from my youth, Play-Doh. It smelled so good! Why do they make it smell so good if they don’t want me to stick it in my mouth? Thankfully, I’ve never been allergic to wheat gluten.
