K-cups have been around for a long time, home units around 2004, with up to 5 billion k-cups sold last year. It is huge competition to coffee sold in a bag. But is there something else coming? Keurig also sells brewers that use new Vue Packs instead of K-Cup Packs. The Vue system offers more control of the brew with a wider range of mug sizes.[18] Unlike K-Cups, Vue Packs can be emptied and recycled after use.
