Tea and how it tastes is such a personal preference thing. I have found drinking tea instead of coffee is easier on my stomach. I must confess I still like the smell of coffee and the taste. Twinings English Breakfast Black Tea is a somewhat mild blend and easy on the stomach. During the day I often have three or four cups. Because they come as K Cups they are very convenient to use in a Keurig Coffee Machine.
Have purchased several Keurig coffee makers and have 2 automatic ongoing coffee and tea orders, which I have had for years. Have never experienced any problems with my orders nor with any of the products we have purchased. Extremely happy with everything about Keurig and their products.
