Best Products To Keep A Cup Warm

1. Keep Your Cup Warm With A Mug Cover

If you drink hot beverages out of a tea cup or coffee mug, try using a mug cover! Mug covers are silicone lids that securely seal the tops of open cups and mugs. Not only do they help keep a cup warm for a long time, but they also protect your beverage from dust, bugs, and curious household pets. They also fit most cup sizes!

I highly recommend purchasing a set of mug covers to use at home. You can buy a large quality set of mug covers for a low price (like this 6 pack mug cover set from Amazon).

Mug covers come in a variety of styles and colors. Choose a design you like best! If you are looking for a budget, cute way to keep your cup of tea or coffee warm at home, opt for a mug cover!

Not only will these mug covers help keep your cup warm, but they are also dishwasher and microwavable safe (just take off the diamond knob before microwaving)!

2. Drink Hot Beverages Out Of An Insulated Cup

Not sure how to keep a cup warm? Why not switch to an insulated cup to keep your coffee or tea piping hot all day long? To keep drinks warm long term, I highly recommend using a high quality insulated cup like this amazing Hydro Flask tumbler.

Although highly quality insulated cups are more expensive than an average coffee mug or tea cup, you can’t beat the insulation. A good insulated cup will literally keep your coffee hot all day! It’s the perfect tea or coffee cup to drink hot beverages on the go or at your desk.

It’s a simple way for keep coffee hot without electricity.

Best Insulated Cup For Hot Beverages

I’m a huge fan of Hydro Flask. Not only are their insulated products excellent at keeping beverages cold and hot, but they also have many beautiful color options.

Their insulated tumbler is an excellent cup to use for hot drinks. I personally use their tumbler to drink hot teas and it will literally keep your drinks hot FOR HOURS.

If you plan to use their tumbler for hot beverages, I highly recommend allowing your coffee or tea to cool down for a few minutes before closing the lid. Since the insulation is so good, you might burn your lip if you drink hot coffee out of it!

I would also note that the lid has an exposed mouth opening. I personally don’t mind it, because it doesn’t impact the insulation. Unless you fill the tumbler all the way up to the lid, your drink won’t spill out if you are driving.

3. Use A Mug Warmer

If you enjoy drinking your morning cup of tea or coffee in your favorite mug, try using an electric mug warmer. A mug warmer is clever product to keep a cup warm for a long time.

Simply place an electric mug warmer on a desk or side table and turn it on. Place a hot cup of coffee or tea on the mug warmer to help keep your beverage hot all day.

Mug warmers are intended to help maintain a beverage’s heat. For best results, I recommend placing a freshly brewed cup of coffee on the mug warmer, rather than using the mug warmer to heat up a cold cup of coffee. This is a great idea on how to keep drinks hot all day!

Looking for the best way to keep coffee hot? This coffee mug warmer by Vobago is absolutely beautiful. Not only is the design gorgeous, but the colors are amazing. I love their blue shade! This product also comes in four other color options.

This mug warmer has three temperature settings so you maintain your coffee’s heat to a temperature of your liking. It also has an automatic shut off after four hours. This is great safety feature in case you accidentally leave your mug warmer on unattended for extended periods of time.

4. Store Your Coffee/Tea In An Insulated Thermos Until You Are Ready To Drink

How do you keep a large batch of coffee or tea piping hot? Store your hot beverage inside an insulated thermos until you are ready to drink!

Although this is not a tip on how to keep a single cup warm, this is a great hack for people who make large amounts of coffee or tea to drink throughout the day. A quality thermos will help keep coffee hot all day long (Looking for an excellent thermos? I highly recommend this thermos from Stanley).

With A Microwave

  1. Fill up your cup with water.
  2. Microwave the cup in the microwave for about a minute.
  3. Pour out the water and fill your cup with a hot beverage of your choice.

  2. Wait for about 5 minutes.
  3. Pour out the water and fill your cup with hot coffee or tea.

This is an easy hack for people who don’t want buy additional products to keep their coffee warm. Although it won’t keep your coffee piping hot all day like a mug warmer or insulated cup would, this is a quick method to keep a cup warm without using electricity or additional products.

A classic method on how to keep a cup warm is to use a cup cozy. Not only are cup cozies effective at preventing burns from hot cups, but they will also help keep your cup of coffee or tea warm longer.

Cup cozies are adorable and fun to use. You can crochet your own cup cozy or purchase one from sites like Amazon. Unfortunately for mugs users (or anyone who uses cups with a handles), most cozies will only fit handleless cups.

However, if you like to buy takeout coffee, this is a great single use cup sleeve alternative. It is also a great way to keep your coffeeshop coffee or tea hot longer without electricity.
