Very tart and apple cidery, as most people have noted.
Not sure if I like it, but I don’t hate it. But it’s a nice tisane, or ‘herbal’ tea.
Edit: For the 12g sample I had, I got 2 cups out of this. Reminds me of the Apple Cinnamon oatmeal I usually give my kids. No… I don’t like the tart, bitter flavour of the apples in this. Not going to get this again, but glad I tried it to see what the fuss was about. My cousin had also gotten a sample of this and rather enjoys it.
