Hm I'd say Yorkshire Gold is the best tea bag. Second tier are Williamson Afternoon and Ringtons Breakfast, Yorkshire Red. Third tier, Twinings etc, acceptable but not lovely. PG Tips is on the third or fourth tier, at least.
Am gonna have to try it!
I'm assuming you can't get Irish tea where you live? Because Punjana would be above all of them.
I would def put Punjana in as super sub for Yorkshire Gold if I couldn't get YG.
