Espresso mugs live or die on small details. If a mug is a fraction too tall, it will not fit under your machine. If it is too small, your usual pour overflows it. If it has no handle, a hot shot is awkward to pick up. The YETI Rambler 6 oz stackable mugs, sold as the 177 ml size, are built around those frustrations, and Pete, a big YETI fan, says he is absolutely loving them.
YETI calls them 177 ml stackable mugs, but Pete is clear about what they really are: espresso mugs, made to fit under most espresso machines. His came in Camp Green, one of his favourite YETI colours in some time, alongside a wide range of other colours. The design combines a stainless steel body, a ceramic lined interior, a handle and a stacking shape.
Watch the video above for Pete’s look at the mugs, including how they stack, how the mug fits under his espresso machine and why the ceramic lining matters for dishwasher use.
Sized to fit under your espresso machine
The headline measurement is height. These mugs stand just under 3 inches tall, which sounds minor until a mug will not slide under your machine. Pete says most espresso mugs he has tried are just a little bit too tall for his Nespresso Inissia, whereas this YETI fits perfectly. He gives the height in the video so you can check your own machine’s clearance before ordering.
Capacity is the other half of the fit. The 177 ml size is, for Pete, perfect for the espressos he likes to make, a little bit more than what his machine considers a standard espresso. The mug holds his usual pour with room to spare, and the description notes it also works for a mini cup of coffee.
Ceramic lined stainless steel that resists staining
Under the colour finish, these are stainless steel mugs like other YETI drinkware, and they are dishwasher safe. The twist is inside: a ceramic lining, the first Pete had seen on a YETI product. YETI gives little information about why it uses the lining, so Pete’s read is based on his other coffee cups, which stain over time, particularly if they are only washed in the dishwasher.
His thinking is that the ceramic lining eliminates that problem, and so far his mugs support it: he has put some miles on them, yet they still look brand new, with no staining whatsoever. The description makes the same point, describing the lining as a way to prevent staining. For cups that live in the dishwasher between uses, that is a practical benefit.
Stacking, the handle and the Camp Green finish
As the name promises, the mugs stack. Pete shows two stacked on each other, and notes that four would stack just the same. For small mugs that tend to multiply in a cupboard, stacking keeps a set tidy in far less space, making a set of two or four realistic in a small kitchen.
The other design choice Pete singles out is the handle. YETI also makes an even smaller version, but that one has no handle, and he does not think it would be as comfortable, nor would it fit the coffee he likes to make. Camp Green also gets an endorsement: one of his favourite YETI colours in some time, and he thinks it looks great on this mug.
Heat retention and the no lid trade off
Because it is a YETI, Pete says the mug keeps an espresso warmer than a little glass espresso cup would. There is a limit to that: there is no lid. The mugs do not come with one, and YETI does not sell one for them, because they are meant for espresso at home rather than travel. No lid makes a difference to how long a drink stays warm.
That trade off makes sense. An espresso is a short drink, finished quickly at home, so an open top and a comfortable handle matter more than hours of heat retention. Anyone wanting a sealed, portable YETI should look at a lidded tumbler instead. YETI describes the build as ultra durable.
Frequently asked questions
How tall are the YETI 177 ml stackable mugs? Pete measures them at just under 3 inches tall, which is why they fit under his Nespresso Inissia when most other espresso mugs he tried were slightly too tall.
Why do these mugs have a ceramic lining? The stainless steel interior is ceramic lined to help prevent staining, and Pete found his mugs still looked brand new with no staining after regular use and dishwasher washing.
Do the YETI stackable espresso mugs come with a lid? No. They do not include a lid and YETI does not sell one for them, because they are designed for drinking espresso at home.
Are the mugs dishwasher safe? Yes. Pete confirms they are dishwasher safe, and the ceramic lined interior is part of why they hold up without staining under that kind of washing.
Verdict
Pete’s conclusion is simple: if you like espresso and you love YETI gear, you are going to love these cups. The size holds his usual pour, the height fits under his machine where other mugs failed, the handle makes a hot drink comfortable to hold, and the ceramic lining has kept his set looking new. The lack of a lid is the only real compromise, and a deliberate one.
For espresso drinkers tired of mugs that are too tall, too small or too awkward to pick up, this is the considered option. Check colours and pricing for the YETI Rambler 6 oz stackable mugs on Amazon and measure your machine’s clearance against that just under 3 inch height first.
