Keurig Models Old to New

#1 Keurig K155 OfficePRO Premier Brewing System (May 2012)

Keurig K155 OfficePRO

My first encounter with the K155 was in an office setting, and it impressed me with its 90 oz. water reservoir and full touchscreen interface—ideal for a bustling environment.

In addition: You can tell from the sentiments of other users, like this enthusiastic coffee enjoyer that the K155 would be a wonderful addition to any office.

#2 Keurig K-Classic (December 2015)

Keurig K-Classic

A staple in simplicity and efficiency, the K-Classic sports a generous 48-ounce water reservoir and offers three serving sizes. It’s been a reliable companion in many of my clients’ kitchens.


The Keurig Classic stands as a bastion whenever Keurig 1.0 vs 2.0 is discussed. This brewer is just that good!

#3 Keurig K15 (December 2015)

Keurig Hot K15 Classic

Perfect for those tight on space, the K15’s compact design and straightforward two-button interface cater to the minimalist in me.

#4 Keurig K-Select (September 2017)

Keurig K-Select

I was thrilled when the K-Select introduced the “Strong” brew feature, with its sleek design and 52-ounce water reservoir, making a bolder coffee a breeze.


You would have to seek out the strongest K-Cup brands to replicate the experience of this function if your coffee maker doesn’t have it.

#5 Keurig K-Elite (February 2018)

Keurig K-Elite Silver

The K-Elite broke new ground with its iced coffee capabilities and temperature control, showing that versatility and innovation could coexist in a single model.

#6 Keurig K-Café (June 2018) & Keurig K-Latte (June 2018)

These models opened up the world of lattes and cappuccinos at home for me, each serving a slightly different need with the K-Café’s larger water tank and the K-Latte’s simpler setup.

#7 Keurig K-Mini & K-Mini Plus (July 2018)

The ultra-compact K-Mini and its slightly upgraded sibling, the K-Mini Plus, were game-changers for clients in small apartments, proving that size doesn’t limit quality.

#8 Keurig K-Duo Series (August & November 2019)

Keurig K-Duo Grey

The K-Duo series bridged the gap between traditional drip and K-Cup brewing, offering flexibility and convenience in one machine.

#9 Keurig K-Compact (November 2019)

Keurig K-Compact

With its 36 oz water reservoirs, the K-Compact became a favorite for those seeking a balance between size and capacity.

Keep in mind:

You might encounter a problem with this model preventing you from brewing all but one cup size, like this user

#10 Keurig K-Slim (March 2020)

Keurig Slim Black

Mirroring the K-Mini’s space-saving design but adding the convenience of a larger water reservoir, the K-Slim fits perfectly into my daily routine.

It is sometimes compared with the K-Classic, and both brewers have their strengths and weaknesses. 

#11 Keurig K-Supreme Series (August 2020 & 2021)

The introduction of multi-stream technology by the K-Supreme series significantly enhanced flavor extraction, marking a leap in coffee quality.  

It also turns out that being able to decide where your reservoir sits is a highly coveted feature and one major difference between both brewers in this series.

#12 Keurig K-Express (September 2021)

Keurig K-Express

As an entry-level model:

The K-Express brought essential features and affordability together, catering to the budget-conscious coffee lover.

#13 Keurig K-Slim + ICED (May 2022)

Keurig K-Slim + ICED

This model brought the refreshing twist of iced coffee to the K-Slim family, becoming a summer essential for me.


This feature also optimized how I make iced specialty drinks with my Keurig.

#14 Keurig K-Café SMART & K-Supreme SMART (September 2022)

Keurig K-Café SMART

These SMART models took personalization to the next level with their advanced features, making every brew uniquely satisfying.

#15 Keurig K-Iced (January 2023)

Keurig K-Iced

The latest in the lineup, the K-Iced, focuses on delivering the perfect iced coffee, making it a standout addition to the Keurig family.
