I hot brewed this to cool it in the fridge and drink it cold. I snuck a sip after brewing (before adding sweetener) and it was so sour it pretty much turned my mouth inside out. Woah! After cooling I had to pour a ton of simple syrup in to even get it remotely sweet. Well, it was fine once I got it to be palatable, but this is definitely not a tea you can drink unsweetened. Not too sad to see it go!
