If they are that bad I'd compost them. While I'm a big supporter of food banks and such I want all the stuff I donate to be at least "acceptable" in quality.

Many times bitter tomatoes can be salvage by canning them in highly seasoned recipes such as Italian Tomato Sauce if one is willing to put in the work. But since home canned foods can't be donated that fact doesn't help the food bank.

I agree with Dave about not donating tomatoes that you wouldn't use yourself. I would not put them in the compost either because you will end up with a lot of volunteers in places that you don't want them next year. Try making sauce with a lot of herbs, then freeze it.

Let a few other people taste them and see if they agree. Compared to store tomatoes they may pass.

I agree. What may be "bitter" to you could be tasty to someone else.
