A K-cup adapter for the Keurig Vue is available at Amzaon.com, Bed Bath & Beyond, and Wal-Mart, as of 2015. Amazon.com and Wal-Mart both offer the K2V-Cup brand, while Bed Bath & Beyond has the Solofill K-Cup K-Converter for sale.
Both products allow the owner of the Keurig Vue to use any K-cup rather than the ones specifically designated for the Vue. The refillable K2V-Cup can also brew any brand of loose coffee grounds, while the Solofill is specifically designed for K-cups. Place these converters into the Vue and start the brew cycle to make a cup of coffee, tea or hot chocolate.
