DNWing the main opinions is always some level of problem (imagine what you would do if your recip had DNW gen and ship) but if you gave examples of drinks you do like (“I love chocolate, spiced drink mix for ciders, water flavorings and infusers, and soda mixes!”) then that negates any burden you may have otherwise placed on your gifter by taking the big two off the table. Tea and coffee will always be easier but as long as you give them some guidance its not a dealbreaker.
