The Keurig single-cup brewing system uses special packaging for coffee, tea and hot cocoa called K-Cup portion packs or "K-Cups". Each K-Cup pack is an airtight pack that locks out oxygen, light, moisture and humidity while locking in freshness and flavor. Simply insert the no mess K-Cup pack into the brewer and hit the brew button for a fresh-brewed, perfect cup of coffee or tea in under a minute. These 2.0 K-Cup packs can be used with all K-Cup brewers. The 2.0 K-cup packs utilize the latest Keurig technology embedded in the foil lid which allows the Keurig 2.0 brewers to read the label and create the perfect brew.
