My favorite decaf is Hydrangea’s El Paraiso decaf. It’s an alt process but it’s not too funky. Very fruit forward. In Canada, hatch has a roast of the same coffee I think.
Rogue Wave’s current decaf offering is good for more traditional medium roast. Along the same lines I’ve enjoyed Mother Tongue’s decaf a lot. Onyx just put out a decaf version of their Geometry blend that sounds interesting but I haven’t tried it yet.
Re: method, if you’re brewing pour over, decaf poses certain challenges due to the brittleness of the beans leading to clogged drawdown. So you may need to grind coarsee or change how agitate to get the best results. (Onyx’s decaf brew guides are useful points of reference)
