english breakfast tea is made up of a traditional mix of different black teas. It ranks among the most favourite mixes and finds its place in the everyday life of the United Kingdom and Ireland. The history of that mix starts in the 19th century when dealers travelled the oceans to trade products, and the custom of drinking tea became always more popular in Europe.

That mix usually is made up of teas from Assam, Ceylon and Kenya. Usually it also holds tasty Chinese black tea, for instance Keemun, that blends with those from Ceylon of Sri Lanka and Assam to give more strong and quick feeling in the mouth. Tea from Assam adds to the whole strong flavour with a bit of bitterness, especially when one overdoes it.

What Is English Breakfast Tea?

Some variants also include tea from Nilgiri, that brings a fresh and bright shade.

english breakfast tea is a kind of black tea, and almost all black teas form mixes. Nothing truly separates the english breakfast tea except the taste of the particular maker. Generally it is a more strong and bold mix.

The quality copies choose hand-picked teas and expert suppliers to create a special mix with brave, full flavuor, that glides in the throat with a quick finish.

In some types the leaves are short and dark. The liquid turns something heavily brown with roasted smell. The flavours are commonly simple and full, with traces of toast and honey.

That tea stays strong and simple. The malty shade shows the presence of good Assam in the mix.

english breakfast teas are not meant too be overpowered by rich foods or sharp spices. They can feel a bit more bitter when one drinks them without extras. The tea owns good strength and fullness to last with milk and sugar.

Adding milk goes well with the rich body and softens part of the edges. Honey forms another good option. One also can enjoy it alone, whether hot or cool.

A normal eight-ounce cup holds around 30 to 60 milligrams of caffeine. This is a middle amount compared to coffee, that usually has 113 to 247 milligrams each cup. The caffeine amount is close to that of matcha, that has around 70 milligrams each serving.

A bigger serving naturally will raise thecaffeine intake.

That tea is meant to provide energy in the morning and go with a big breakfast. It works also as an everyday boost. If it seems ever weak, that probably means that it got old or became stale.

Quality english breakfast tea never is weak. Irish and english breakfast teas differ a lot depending on brands, because both depend on different sources in their mixes.
