ELI5: Why don't you hear about "fair trade" or "single source" when it comes to hop farmers for beer and grape farmers for wine, but you hear it all the time when it comes to coffee bean farmers?

You always hear about coffee bean farmers getting ripped off and the initiative for consumers to help alleviate this issue by only buying fair trade or single source or both. Why don't you hear about these issues with grapes or hops for example?

Fair trade is mostly to protect international farmers.  They get ripped off in third world countries.  Coffee is grown in tropical areas, so there are not many places in America or first world nations in general where they can be grown.  Coffee is native to Africa and much of it is still grown there.  Jamaica is another big growing market.  In the U.S., there are Hawaii growers but they are very small and "premium".

Hops, on the other hand, are overwhelmingly grown in Washington State.  The vast majority of hops in the US are from Yakima Valley.
