After enjoying some of Butiki’s flavored guayusa blends (Good morning sunshine is my favorite, but the Killer’s vanilla is good, too!) my husband asked me to get some straight guayusa so we could taste it by itself. It is quite nice! Not too strong a flavor, actually. Pretty mild and grassy, and sort of nutty. Very stimulating! It is very drinkable straight but I would still prefer to drink a flavored one because why not?
