Time and temperature measuring

Whether it’s your favourite cake or a boiled egg for breakfast, to achieve perfect results in the kitchen, two measures are decisive: time and temperature. TFA has the right measuring instruments for both tasks at hand.

In the beginning was the egg

It’s not for nothing that kitchen timers are often called “egg timers”. Time plays a big role in the preparation of this breakfast classic and has a personal preference. The German comedian Loriot illustrates this with a lot of humour in his sketch “Das Frühstücksei” (the breakfast egg). 

When is an egg hard, soft or still raw?

The cooking time is also closely related to how the eggs were stored. If they come straight from the fridge into the saucepan, they will need to boil for a few more seconds to reach the desired consistency. It’s therefore recommended to take the eggs out of the fridge a few minutes beforehand.

Our table helps you to cook perfect eggs for breakfast (based on a medium sized egg):

Hardness Cooking time
Runny eggs 3 minutes
Soft-boiled 5 minutes
Medium-hard 7 minutes
Hard-boiled 10 minutes


Bring the water to a boil. Once it boils, add the eggs and set the egg timer. Now you can look forward to perfectly boiled eggs for your breakfast, every time.

It’s coffee time!

Let’s continue with the breakfast. Are you a coffee drinker or do you prefer tea? For the preparation of these two hot drinks, the correct water temperatures as well as the brewing times are crucial.

Coffee lovers will be probably surprised now. A mild coffee should take about four to six minutes to brew! For mocha and espresso, 30 to 60 seconds are enough. These brewing times are standard in most coffee machines. With a pour-over coffee – using a drip coffee filter holder – you can regulate the time by adding the water slowly.

The ideal water temperatures for brewing are between 86 ºCand 96 ºC. You can check the water temperature with a probe thermometer. The convenient fold away probe thermometers “THERMO JACK” are ideal for easy temperature measuring at home.


Perfectly frothy

Viennese mélange, cappuccino or latte macchiato are now standard coffee options on most hotels, restaurants and high-street cafés or coffee shops.

The variations around coffee are impressive. Have you ever observed a barista working? The coffee is ground and brewed with the most concentration and attention to detail. The masterpiece is the milk froth and the how the froth is mixed with the coffee or simply put on top of it. The challenge is to froth the milk at the correct temperature. For wannabe baristas to coffee maker experts, we have the perfect tool for this task:

There’s always time for tea!

Serious tea drinkers know that their favourite hot beverage is only perfect if the appropriate brewing time is given. Depending on the type of tea, this can be between three to eight minutes.

Black tea and green tea have a stimulating effect if left brewing for three minutes; from five minutes the tea will often taste bitter. Important is the correct water temperature during preparation. Now it’s time to debunk this popular belief: you should always pour boiling water onto tea. The water for brewing black tea has the right temperature immediately after boiling; with green tea, you should wait at least a minute before pouring the water. Thankfully you can count on our probe thermometer or the tea thermometer, which has been specially designed with tea lovers in mind.

Tea type Water temperature Brewing time
Black tea 90 °C – 95 °C 3 – 5 minutes
Green tea 70 °C – 85 °C 3 – 4 minutes
Rooibos tea 90 °C 5 minutes
Herbal tea 95 °C 6 minutes
Fruit tea 95 °C 6 minutes


By the way, the ideal drinking temperature for hot beverages is between the average body temperature 37.0 °C and a maximum of 43 °C.

Here’s another time that plays an important role: the time for your enjoyment! Instead of a “coffee to go” why not take your time and enjoy this amazing drink? Give caffeine time to develop. We’ve never heard of rushed tea drinking, so our advice is: Keep it up, relax and enjoy your tea!

Temperature for beverages

A well-tempered wine as a companion to food is no challenge with our digital wine thermometer. Whether white, red or rosé, wine remains entirely linked to the taste and choice of food. The drinking temperature for this fermented grape juice is between 8 and 18 degrees.

 White wines are best consumed cool and at 8 to 14 degrees. A red wine has the perfect temperature between 12 and 18 degrees. Those who prefer a rosé or a Rotling wine, enjoy this best at moderate 10 to 14 degrees. With our wine thermometer, the temperature can be easily determined from outside the bottle.

A cold beer is the ideal companion for after work or for a BBQ. Here, cool has a different meaning. While you drink a non-alcoholic beer at 4 to 6 degrees, a larger (e.g. pilsner) should, however, be tempered to 8 degrees to savour its full taste. The recommended drinking temperature of Belgian-style beers (i.e. beers with high alcohol content and low bitternesssuch as pale ales, dark ales, fruity beers and sour ales) is 12 to 14 degrees – which could be described as warm by comparison. Our wine thermometer can also determine how warm your bottle of beer is. Just place it around the bottle, read it and cheers!

Another piece of advice: It’s best to ensure the ideal storage temperature in a wine fridge or refrigerator.

This is how it happens at home
