It's the strongest stuff I've ever had. (And I drink Turkish coffee over here from time to time.) It's also delicious.
On my first trip to Argentina, they served yerba matte in the morning and had these little demitasse cups. I said "To hell with that," and poured mine into a regular coffee cup.
Right before an all-day meeting.
I was kicking the table legs, shifting in my seat and had a huge desire to climb the walls in the conference room.
I never made that mistake again.
