That’s heavy on the robusta side, right? I guess it is adapted to the way it is brewed. I drink my coffee as espresso shots, some blends are simply not made for that.

High quality single source Vietnamese robusta can be great for super rich flavoured, and high caffeine espresso! In general Vietnamese robusta has higher caffeine and more complex flavour pallet. My personal favourite is cherry bean with ice in the summer! So if you like flavours and high caffeine try it!
