Buyers Guide for the Best Insulated Coffee Mugs

What size would you need?

Insulated coffee mugs vary in capacity. They are available anywhere from 12 oz to 20 oz or more.

If you’re just an average coffee drinker, you might be okay with smaller capacity mugs. A 12 oz to 16 oz would be fine.

On the other hand, if you’re a coffee binger, you’d need a larger capacity. An 18 oz or more capacity coffee mug might be enough for your caffeine appetite.


Ceramic or Metal?

The preference between ceramic and metal differs for each individual. Most coffee enthusiasts would prefer a ceramic insulated coffee mug because it allows you to enjoy better-tasting coffee than their metal counterparts.

The downside of a ceramic coffee mug, however, is durability. Ceramic is tough, but it’s not shatter-free, unlike metal.

On the other hand, stainless steel insulated coffee mugs are also great at insulating temperature. But the metal feel is not so pleasant to the lips as you take each sip.

On the other hand, insulated stainless steel mugs are tough and could last a lifetime. So, depending on your preference, would you pick ceramic or metal?


Aesthetics Count

As you will discover, insulated coffee mugs come in different designs. Most stainless steel mugs were coated with paint, and ceramic mugs are often glazed.

Insulated ceramic coffee mugs do not have much problem with paint scratching off their surface because of the glaze treatment. On the other hand, stainless steel mugs coated with paint usually have issues of color being peeled-off, scratched, and fade.

However, with proper care, paint-coated stainless steel mugs may last long without any damage to its surface. But if you don’t want to have trouble with paint-related problems, you may always choose the polished stainless steel mugs.


With or Without Handle

Handle gives you more control and is more comfortable to hold, especially if you’re sipping coffee from a wide mug. It also slightly protects you from scalding when accidental splash or spill occurs.

On the other hand, a handle may cause your mug to not fit in some car cup holders.


Lid Design

Not all mug lids are designed equal. Most insulated coffee mugs come with a slider lid, which is easier to use, but the downside is when it comes loose.

A loose slider lid may block the opening when you try to tilt your mug to get a sip. There are some insulated mugs with a flip-top to open a sip hole.

These flip-top lids may not be convenient for some users as some would need to use both hands to open the cover. And also, when the lid’s not tough enough, it may break off easily, affecting your mug’s insulating capabilities.

Frequently Asked Questions

What is the best insulated coffee cup?

The best insulated coffee cup would depend on your specific needs. Going over on our buyers’ guide will help you decide which insulated coffee mug is best for you.

However, we’d pick Contigo for daily commute to work as you don’t have to worry about leaking. But if you want something smaller in capacity, the Thermos King is our favorite.

If you love the outdoors, we’d recommend the Stanley Admiral’s mug. It has a wide base that provides more stability on uneven surfaces, which makes it perfect for campings.


What coffee mug keeps coffee the hottest?

How long an insulated coffee mug retains hot temperature depends on some factors. The temperature in the surroundings could affect the efficiency of a mug’s insulation.

If the weather’s too cold, an insulated mug may not hold hot temperatures well. Keep in mind that insulated coffee mugs are not built to be as efficient as thermoses.

Additionally, these insulated coffee mugs were tested at room temperature.

Another factor that affects how an insulated coffee mug retains hot temperatures is how often you take a sip. As you take a drink, you’d be opening the lid, and hot temperature escapes through the opening, lessening the efficiency of the vacuum insulation.

So, what coffee mug keeps the hottest? Based on our review, we’d give the most efficient heat insulation to Contigo for the 20 oz capacity, and Thermos King for the 16 oz capacity mugs.


Who makes the best insulated tumbler?

One brand could be useful for one user but may be worse for another. It’s merely because different coffee lovers have different views for each product.

From our review, you’d find different pros and cons for each insulated coffee mug—the question of who makes the best insulated tumbler would still depend on your own specific needs.
