I got this at starbucks once and it was flavorless, so I bought the teabags myself, thinking it would taste better. I've used up to 3 teabags at a time and it's still WEAK and flavorless. Im caffeine sensitive and this tea doesn't seem as high in caffeine as it says it is. It didn't cause any heart palpitations or anything. Try PG tips tea bags- it's WAY better, strong and robust
