Perhaps perhaps the most important criterion when choosing the right thermos, to maintain the temperature of your drink for as long as possible. Whether it's a hot or cold beverage, we want to enjoy it a few hours later. The thermos should have a double wall to help maintain the temperature, ideally made of stainless steel. Equally essential is the cap, which should not only seal well, but should also serve for pouring. We often use a thermos to serve coffee or tea, so safety is important. A smooth flow will prevent the risk of burns and spills. After all, a dirty tablecloth certainly doesn't look good.
We mustn't forget about washing up either. The thermos is best cleaned with a long-handled brush and detergent. It's a good idea to choose the right one depending on the type of beverage, but the best products are those that also clean coffee or tea deposits.
