This was always the problem with Vietnam, they grew shit coffee because they had nothing, and something is better than nothing.

I was there 8 years ago, and the coffee is absolute crap, even the premium stuff with a fancy hotel.and branding.

When I was there, the landmass had been almost filled with coffee where applicable. It led to lots of income, but efforts were underway to provide loans and education on how to grow better Coffee to utilize the same amount of land, same amount of production, but get more money out of said grown Coffee.

Perhaps this article is an acknowledgement of the hard work of the people of Vietnam to produce more valuable coffee from their land.

I can't say. I can only say it used to be absolutely horrendous, to the point that "Mixto" was a thing. Producers would roast with corn syrup and other stuff to try to make a better coffee bean. The beans really really were that bad.
