Why buy a tea thermos?

Some tea drinkers like to brew tea separately with leaves, then remove the leaves with a strainer. This hassle is eliminated with a thermos tea infuser, which can brew and strain the leaves with ease.

We understand that the importance of having a thermos infuser lies in the type of infusion you like to make. Indeed, there are infusions of tea bag drinks and loose tea. While the former is limited in terms of antioxidant production, the latter is not.

Clearly, loose tea offers tremendous health benefits and is packed with flavor. The leaves fully expand and release potential antioxidants to:

  • fighting the cold;
  • improve heart health;
  • maintain brain health.
  • Therefore, to enjoy a perfect cup of healthy brewed tea, you need a tea thermos with an infuser.


What size infuser thermos to choose?



Infuser thermos jugs are available in a variety of sizes and it should be noted that this refers to their capacities. Depending on the needs, there are three size formats for infuser thermos:

  • The small size: it takes into account infuser thermos ranging from 250 to 500 ml ;
  • The medium size: with thermos jugs with a capacity of 500 ml to 750 ml;
  • The large size: with thermos jugs with a capacity of more than 1 liter.

When selecting the size, think about your daily tea consumption.


How to recognize a good thermos jug?

When you are looking for a tea thermos, there are some things you need to take into account to choose the best product on the market. Let's read together the important points to keep in mind when making your purchase:

Focus on insulation

Thermal insulation is the technique by which your beverages will keep warm for a long time. It is a criterion not to be neglected if you intend to take your thermos tea infuser everywhere. To this end, check if your container has the right insulating structure:

  • Vacuum insulation

Vacuum insulation works by preventing heat transfer from the outside of the infuser thermos to the inside. It does this by creating a vacuum in an inner wall. Since there is no air in the vacuum, convection cannot occur and the temperature of the liquid remains stable.

  • Foam insulation

Foam insulation works by using foam to prevent convection. It is then difficult for air to move through the foam. Therefore, heat cannot be transferred from the outside of the bottle to the inside.

Choose the material carefully

The material is one of the most crucial factors to consider when selecting the best thermos jug. Generally, there are three types of materials: stainless steel, glass and plastic.

  • Focus on stainless steel

Stainless steel wall infusers are exceptionally durable and stronger. They are also lightweight, which is a great quality, in case you want to take your infuser tea thermos with you. In addition, stainless steel infuser thermoses are usually vacuum sealed. This allows them to keep drinks cold or hot for long hours. Finally, they are resistant to discoloration, odors and scratches.

  • Focus on glass

Glass infuser tea thermos jugs offer an aesthetic touch to your drinks, as they are both beautiful and elegant. With them, you can see exactly what's inside. In addition, the thermos jugs allow you to control the strength of the infusion according to the color. Finally, they are safe to wash in the dishwasher.

  • Focus on plastic

Thermos jugs made of plastic are the least used, as the boiling water and the material do not complement each other very well. However, you can find plastic infuser thermoses that are BPA-free. They are excellent for drinking hot tea without health hazards. Finally, plastic infuser thermos jugs are lightweight and unbreakable if dropped.

Think about the type of infuser



The type of strainer you choose will impact your finished brew. Therefore, choose a fine mesh strainer. It will allow you to get a more refined tea, as it can filter out even the smallest pieces. On the other hand, you can also choose stainless steel strainers. These are excellent solutions to obtain more dilated leaves during the infusion because of its sieve with large holes.

Further, some infuser thermos packs include a two-part strainer. This is a filter to be used for the brewed water and a leaf infusion basket.

Don't forget the infuser lid

You should not overlook the lid when purchasing your infuser thermos. It is an important accessory to ensure the bottle is watertight. Most of the time, they come with a flip top or screw top.

At Healthy Lunch, we take the experience to the next level for your enjoyment with silicone flip top lids that sport a sporty look. With this equipment, you can comfortably hold and sip tea with one hand without any risk of leakage.
