Definitely not a bad tea. To me, it’s sort of like a Genmaicha, but without all the toasty rice flavour that I find so off-putting. I often find Genmaicha way too vegetal and sort of dirt-y tasting. The maté thankfully has none of those notes, just a subtle toasty-ness that is definitely not unpleasant :)
Nice on a summer evening after a light meal, or as a companion for your morning commute.
