Making a good cup of tea takes a little time, patience and practice. It's no different to other types of food preparation - how many of us made a perfect cake first time ? So use the basic principles of tea making and then experiement until you get the tea you enjoy drinking. You'll be surprised how quickly you can master it.

Whether you are making tea in a teapot or in an infuser mug the basics are -

Use clean, fresh water. Filtered water is probably best as spring and some tapwaters have strong mineral tastes.

Never let the water go to a rolling boil, even on teas that can take boiling water as this removes all the oxygen from the water and affects the taste. Using a kettle with a built in thermostat like the Aquagrad available on Amazon.

Use fresh tea - buy tea in small quantities and use it as fresh as you can to get the best taste experience you can

Use the right amount of tea - use a measuring scoop/spoon or scales

Infuse for the correct amount of time - use a timer, preferably one with minutes and seconds.

Infuse at the right temperature - use a thermostatically controlled kettle or a kitchen thermometer. 

If you use an infusion basket take it out of the tea as soon as it is ready.  

Store tea well when not in use. Keep in an airtight, dark container away from any other strong tasting or scented items.  

Finally, you can adjust the times and temperatures for various teas until you get your perfect cuppa. It's really well worth the time and effort. You'll soon find that when you are travelling rather than put up with the bland teabags offered in some hotels you develop your own little travelling kit - tin of tea, strainer,thermometer and timer..aahhhh bliss.....
