The Bottom Line
One of Keurig's most iconic brewers, the B45 is easy to operate with a solid 48 oz reservoir, but it has just a 10 oz max brew size and no special features. Now discontinued, check out the K45 or K-Classic instead.

Keurig B45 Overview

Want to know one of the most common Keurig-related questions we're asked?

What's the difference between Keurig's B series and K series brewers?

Answer: Nothing. The switch from B to K was solely a marketing decision as the company realized branding their brewers with a K made more sense. (They're called Keurig, after all.)

The B45 is part of Keurig's flagship B40 series. Currently discontinued, it was replaced by the K40 series.

In turn, the K40 series was rebranded as the K50 series, and eventually the B40s, K40s, and K50s were all discontinued and replaced by the K-Classic, which offers many of the features you'll find on B40/K40/K50 brewers:

  • 48 oz reservoir
  • No Strength Control or Temp Control
  • Auto-On/Off functionality and removable drip tray
  • No pod-scanning system (found on Keurig 2.0 brewers) so it's compatible with all types of K-Cups

There are just two major differences between the B40/K40/K50 brewers and the K-Classic:

  • The K-Classic's slightly expanded brew sizes (6, 8, and 10 oz)
  • Its upgraded brewing system that ensures you're brewing with Keurig's latest and greatest technology for hotter, stronger cups
Pros
  • No pod-scanning technology so brews both licensed and unlicensed K-Cup pods
  • Foolproof to use
  • The iconic brewer that put Keurig on the map
  • Comes with K-Cup variety pack
Cons
  • Discontinued model
  • Only 2 brew sizes (8 oz, 10 oz)
  • No Brew Strength, Temp Control, or other features
  • No water filter starter kit or reusable My K-Cup

Is the Keurig B45 for you?

Are Keurig B45 for you?

The discontinued B45/K45 is still worth purchasing if you can get a good deal. It doesn't have any outdated tech that limits its usability and is still a quality model if you don't mind losing the 6 oz brew size.

However, we really do recommend going with the K-Classic, which is currently in production, supported by Keurig, and has all of the features you'd find on K40-K55 brewers.

Keurig K-Duo Plus

Keurig K-Duo Plus
Overall Rating: 88
The K-Duo Plus is Keurig's most versatile coffee maker, brewing both single-serve K-Cups (up to 12 oz) and full 60 oz carafes with a convenient swivel water reservoir designed to fit your counter's configuration.

Keurig K-Express

Keurig K-Express
Overall Rating: 85
Keurig's cheapest, most basic brewer, the K-Express measures less than 5" wide (just like the K-Mini and K-Slim) with 8-12 oz brew sizes, Strength Control, a 7" cup clearance. For compact Keurigs, it beats the K-Mini easily.

Keurig K-Mini

Keurig K-Mini
Overall Rating: 84
The super-slim successor to the K10/K15, the Keurig K-Mini is just 4.5" wide and brews 6-10 oz with its "fill before each use" reservoir. If you want fancy features, look elsewhere. If you want compact coffee, look here.

I'm Bryan but most people know me as The Coffee Maven. I grew up outside Boston, Massachusetts and received my Bachelor's degree in Biochemistry from Providence College. My first introduction to coffee was during my college days, when I used it as a source of caffeine to fuel late-night study sessions, but soon I became obsessed with the chemistry of coffee. How did changes to water temperature or contact time affect its taste? Why do beans from Africa taste fruity while beans from Indonesia taste spicy? I launched The Coffee Maven in February 2017 to explore these questions and help others brew their perfect cup. Welcome to my site, and thanks for reading!
