Moments of aromatic pleasure with the right vacuum jug for you
Be it at breakfast, mid-morning in the office or during your afternoon coffee break: nothing beats a hot, aromatic cup of coffee or tea with that freshly-brewed taste. But how can these tasty hot drinks keep their flavour and stay at the perfect temperature? The right vacuum jug will keep coffee & co. deliciously hot even for up to twelve hours, giving you many moments of pleasure. So how does it work? We reveal all!
Vacuum jugs – the multi-talented choice for every household
Vacuum jugs can be found in almost every home. With all sorts of designs ranging from traditional stainless steel to brightly-coloured plastic, they make a truly eye-catching addition to any laid table. The insulating action of these vacuum jugs keeps coffee, tea & co. tasting delicious and (most importantly) hot for up to twelve hours, so they are an absolute must for the office, at parties or when enjoying a coffee with family and friends.
The inside of the vacuum jug is what makes it work
Heat always flows from hot objects to cool objects – that’s what the second law of thermodynamics states. But how does the vacuum jug manage to prevent the temperature inside the jug from adjusting to the colder outside temperature?
- The jug is fitted with a double-waller liner made from either glass or stainless steel.
- The liner works in exactly the same way regardless of the material: there is a vacuum between the two walls, and this prevents the heat from the jug escaping to the outside.
By looking inside a vacuum jug with a glass liner, you will be able to see that the inside is a silver colour. The reflective surface inside the jug also helps ensure that less heat can escape. This is down to the reflective effect of the interior. With hot objects such as a vacuum jug filled with coffee, part of the heat is emitted by heat radiation. The mirror-like interior of the jug reflects this heat radiation and makes sure the heat is kept inside.
The EMSA vacuum liners keep beverages like coffee or tea hot and full of flavour for twelve hours. The liner consists of five layers: firstly, two layers of hardened borosilicate glass preserve the natural flavour. Then two additional genuine silver layers reflect the heat to keep the beverage perfectly warm. A vacuum layer is also included to provide additional heat insulation. But it isn’t just the interaction between the five layers that makes the break-proof liner so unique; it is also hand-blown and hand-made.
Why hot drinks stay the same temperature inside the vacuum jug:
- The inner vacuum liner facilitates heat storage.
- What’s more, the reflective interior in vacuum jugs with glass liners ensures that less heat can escape.
Turn, tilt, press: finding the right closure
A safe closure is another important criterion for a good vacuum jug.
Vacuum jugs: what different kinds of closures are available?
The EMSA vacuum jugs come with a wide range of closures:
- Easy Open closure: the Easy Open closure is designed to help you serve exactly the right amount. All it takes is a simple press of the lever to pour out the contents – then nothing can stand in your way of enjoying a delicious hot or cold drink.
- Quick press & Quick Tip closure: the Quick Press and Quick Tip closures are 100% leak-proof, allowing you to pour the exact amount you need drip-free with just one hand – either with the touch of a button or the tip of your finger.
- Basic twist-off closure: a quarter of a turn is all you need and the jug is ready for serving. 100% leak-proof, for 100% flavour.
- Aroma Control: a vacuum jug that indicates whether or not the coffee still tastes good – this is something only Aroma Control can do. Thanks to the built-in aroma disk in the 100% leak-proof Basic twist-off closure, the integrated precision needle immediately points to the right when freshly brewed coffee is poured into the jug. The needle then points back to the left once the drink has lost its taste. So coffee lovers can rest assured that only the best flavour will ever make it into their cup.
Help your vacuum jug last longer
Cleaning your vacuum jug: tips and tricks
Whether you wash it in the machine or by hand, prolonged use of the vacuum jug can result in coffee and tea residue accumulating in the vacuum jug, and this is sometimes also accompanied by unpleasant odours. These four tips, which range from quick fixes to more time-consuming solutions, will help you clean your vacuum jug so you will be able to use it for a long time:
- The smart fix: one to two teaspoons of table salt or a dishwasher tab mixed with hot water will have your jug looking as good as new in no time at all. Just remember to give it one good shake!
- Just leave it to stand: pour some hot water over a packet of baking powder and leave it to soak for half an hour. Then rinse well and enjoy the wonderful new sheen of your vacuum jug!
- Farewell, odours: denture cleansers can also be used to get rid of unpleasant odours. They are normally used to dissolve the dirt that accumulates on dentures, but they will also give your jug a thorough clean. Once again, the magic word for this solution is hot water. Simply pour it over the tab, give it a shake and everything will be nice and clean!
All EMSA vacuum jugs, for example the AUBERGE Aroma Control or the ELEGANZA, are guaranteed for at least five years.
Teapots for unique moments of pleasure
Feel like getting away from the daily grind? Have a large cup of tea – preferably from an EMSA teapot "Made in Germany". EMSA teapots will keep your tea hot for up to 12 hours and aroma fresh thanks to the aroma tea-strainer.
And by the way: Delicious tea leaves unfold their full aroma when brewed between
122 °F and 203 °F. Then, let the tea cool off a bit and enjoy.
