Twinings has been blending my family tea for years. Today, I am proud to continue this tradition with the tea celebrated throughout the world known as Twinings Earl Grey. Legend has it, that my ancestor, the second Earl Grey, was presented with this exquisite recipe by an envoy on his return from China. Each of the two boxes come packed with 24 K-Cups that can be used with any style or model of Keurig brewing machines.The Keurig single-cup brewing system uses a special packaging for coffee, tea and hot cocoa called K-Cup portion packs or "K-Cups". Each K-Cup is an airtight, mini-brewer that locks out oxygen, light, moisture and humidity while locking in freshness and flavor. Simply insert the no mess K-Cup into the brewer and hit the brew button for a fresh-brewed, perfect cup of coffee or tea in under a minute.
