Get yourself a little Coffee Arabica plant and grow it in a pot at home. If you put it outside in summer, it will like that along with humidity and acid soil (plus it doesn't like nights that go below the 50s, so watch the weather in fall). It does well as an "understory" plant.
I have one overwintering in the basement right now. It takes about 7 or more years before it is mature enough to flower when growing from baby sprouts but the flowers have a nice jasmine scent and will form clusters along a branch, eventually producing berries. Obviously young shrubs won't have much but over time as the plant matures, you can get a couple handfuls of beans and at least you know the source!
Mine is almost floor size (I had one previously about 20 years ago and had gotten as big as the below but some plant that I bought ended up with mealy bugs that got on the coffee and battling that was a nightmare, and I finally gave up) -
Below is Logee's that sells them (my current one is from there but it was a 4" plant when I bought it about 7 years ago) -
