In August 2014, Keurig unveiled their 2.0 brewing system, which added 2 new (big) features:
The Keurig 2.0 brewers came in 4 different series — K200, K300, K400, and K500 — with each series progressively adding more features.
Within each series, Keurig released multiple different models. For example, the K500 series includes the K500, K525, K545, K550, and K575.
Here's the important part: All brewers in each series are exactly the same. That's right, the K525 and and all other K500 brewers are the same machine. The only difference is what's included when you buy the brewer.
Specifically, each model number includes (or doesn't include) these accessories:
Our Buyer's Guide section below covers the differences between all 4 series (plus this K525 model versus other K500 brewers).
In this section, let's look at the entire Keurig 2.0 system.
First, all Keurig 2.0 models brew 10 different sizes from 4-30 oz using one of four different types of pods:
Unfortunately, K-Mug, K-Vue, and K-Carafe pods have since been discontinued, which eliminates the major selling point of these brewers.
Second, all Keurig 2.0 models have some type of digital touchscreen interface, Keurig's new Quiet Brew Technology, which actually is less noisy than their original brewers, Strength Control for a stronger cup, and a High Altitude setting.
