Ninja PB051, Ninja CFP101 or Cuisinart SS-9?

The Ninja PB051, Ninja CFP101 and Cuisinart SS-9 all brew one serving, but their cold-drink routes and vessel choices are not interchangeable. The PB051 keeps a pod or grounds menu in a compact unit; the CFP101 adds a glass carafe; and the SS-9 separates grounds Cold Brew from pod Over Ice. Decide first whether you need a pot for more than one person, then decide what “cold coffee” actually means to you.

PB051: the most compact two-format routine

The Ninja PB051 review covers a single-cup brewer with grounds sizes from 6 to 24 ounces and regular pod sizes from 6 to 12 ounces. Its grounds filter and Ninja Pod Adapter share one brew basket, so changing formats involves switching inserts. It offers Classic, Rich, Over Ice and Specialty. The Specialty option is a fixed roughly four-ounce concentrate for a milk drink; it is neither a four-ounce pod-size choice nor a demonstrated espresso shot.

The Over Ice button works with pods as well as grounds, but it brews hot coffee into a cup already filled with ice. There is no separate grounds Cold Brew mode. Its fold-away whisk can foam milk but does not heat it; it is not a steam wand. Select this one when a compact single-serve footprint, pods and grounds, and an occasional iced or concentrate drink matter more than carafe capacity.

CFP101: same cup routes, with a full pot

The CFP101 also accepts grounds and compatible pods and can brew Over Ice with pods. The difference is that it includes a 12-cup glass carafe and a warming plate, alongside its single-serve menus. It is better when one household needs individual cups on some days and a shared pot on others. The trade is counter space, a carafe cleanup, and a warming-plate routine. It does not solve a requirement for grounds Cold Brew or heated milk frothing.

Neither model's Over Ice setting should be confused with cold steeping: both put hot coffee into a serving vessel of ice. If you want the machine to keep a large batch ready, choose the CFP101's pot configuration; if most brews are one cup and space is tight, the PB051 is the more direct shape of machine.

SS-9: two genuinely different cold paths

The Cuisinart SS-9 lacks a carafe too, but the manual documents grounds Cold Brew with its reusable HomeBarista XL cup and a separate pod Over Ice route. The grounds cup has a 16-ounce size, larger than the PB051's grounds menu does not include. Its distinction is useful if you specifically want cold-water grounds brewing and pod convenience in one machine. The Cold Brew cycle is not the quick hot-over-ice recipe: it uses ambient water and takes longer.

Make the answers fit one routine

For a regular pod Over Ice cup, all three have a documented path. For a grounds Cold Brew path, the SS-9 is the one of these three with that operation in its manual. For a glass carafe plus pod cups, the CFP101 is the fit. For a compact, carafe-free grounds/pod brewer with a built-in whisk and fixed Specialty concentrate, look at the PB051. If your essential requirement is both a carafe and true grounds Cold Brew, none of these three facts describes that combination; broaden the search rather than joining features from separate products.

Before buying, confirm the exact model code and package. Pods do not have a universal physical format, the PB051 manual warns against forcing a pod that does not fit, and the SS-9's 16-ounce grounds selection is not a pod size. If you need hot milk, choose a steam-capable machine or plan to heat milk separately; a whisk alone only adds foam.
