Try a local specialty roaster, most will have decaf. There are different processes as you mentioned, the one I see a lot is called Swiss Water process, that’s generally going to be the muddiest in terms of flavour. I’d steer away from that, and focus on other options. I’ve found Sugarcane/EA/ethyl acetate to be the best from my experience and it’s probably the second most common. It’s got a few names so I mentioned them all but they’re all the same process. Aside from that, go for flavour notes you know you’ll enjoy. Do you have much experience buying specialty coffee? If not I could try and give you a guide for decoding flavour profiles on bags to try and find what you’ll enjoy.

I have enjoyed these beans:

They are not as good as a good caffeinated bean but better than a mediocre caffeinated bean. I use them for my 2nd cup of the day to limit my caffeine intake.

Let us know whatever you try and enjoy!

I had to give up cafine as well. I’m out in the middle of nowhere so roasters is not a great option. I like kicking horse coffee pretty well. Their decaf tastes like regular coffee to me.

Seconding the advice to just check local roasters.

If you’re looking for cheaper it’ll be challenging. Wegmans carries a couple whole bean decaf varieties (espresso and something medium roast). Trader Joe’s always seems to have whole bean French roast. And there’s some bulk ones on Amazon probably worth a shot - used to get SF Bay decaf there.

Colombia, El Carmen. But you have to find a roaster who does it well. In the UK I recommend James Gourmet Coffee’s roast of it. Somehow they’re able to get the kind of sweet fruity notes that you normally never expect from a decaf. I’ve tried the same beans from other roasters and they taste like a run of the mill high quality decaf, chocolate and nuts, meh.
