Production

Matcha is made from shade-grown tea leaves also used to make gyokuro
Gyokuro
Gyokuro is a fine and expensive type of green tea from Japan. It differs from the standard green tea known as sencha , because it is grown under the shade rather than the full sun. Another Japanese green tea that is shaded during growth is kabusecha , which differs from gyokuro in the length of...

(jade dew) tea. However, if the leaves are laid out flat to dry, they will crumble somewhat and become known as tencha . Tencha can then be de-veined, de-stemmed, and stone ground to the fine, bright green, talc-like powder known as matcha.

It can take up to one hour to grind 30 grams of matcha.

Note that only ground tencha qualifies as matcha, and other powdered green teas, such as powdered sencha

Grades

Matcha is generally expensive compared to other forms of tea, although its price depends on its quality. Grades of matcha are defined by many factors.

Location on the tea bush

Where leaves destined for tencha are picked on the tea (Camellia sinensis
Camellia sinensis
Camellia sinensis is the species of plant whose leaves and leaf buds are used to produce Chinese tea. It is of the genus Camellia , a genus of flowering plants in the family Theaceae. White tea, green tea, oolong, pu-erh tea and black tea are all harvested from this species, but are processed...

) bush is vital.

The very top would have developing leaves that are soft and supple. This gives a finer texture to higher grades. More developed leaves are harder, giving lower grades a sandy texture. The better flavour is a result of the plant sending all its nutrients to the growing leaves.

Treatment before processing

Tencha leaves are traditionally dried outside in the shade and are never exposed to direct sunlight. However, these days, drying has mostly moved indoors. Quality matcha is vibrantly green also as a result of this treatment.

Stone grinding

Stone grinding is an art form in and of itself. Without the right equipment and technique, matcha can become "burnt" and suffer degraded quality.

Oxidation

Oxidation is also a factor in determining grade. Matcha exposed to oxygen can easily become compromised. Oxidized matcha has a distinctive hay-like smell and a dull brownish green colour.

Traditional preparation of matcha

There are two main ways of preparing matcha: and .

Prior to use, the matcha is often forced through a sieve
Sieve
A sieve, or sifter, separates wanted elements from unwanted material using a woven screen such as a mesh or net. However, in cooking, especially with flour, a sifter is used to aerate the substance, among other things. A strainer is a type of sieve typically used to separate a solid from a liquid...

 is used to force the tea through the sieve, or a small, smooth stone may be placed on top of the sieve and the device shaken gently.

. Otherwise, it can be scooped directly from the sieve into a tea bowl.

A small amount of matcha is placed into the bowl, traditionally using a bamboo scoop called a chashaku, then a modicum of hot (not boiling: 70–85°C or 158–85°F) water is added. The mixture is then whisked to a uniform consistency, using a bamboo whisk known as a chasen. There must be no lumps left in the liquid, and no ground tea should remain on the sides of the bowl. Because matcha can be bitter, it is traditionally served with a small wagashi

sweet (intended to be consumed before drinking), and without added milk or sugar. It is usually considered that 40 g of matcha will provide for 20 bowls of usucha or 10 bowls of koicha:

Usucha, or thin tea, is prepared with approximately 1.75 grams (amounting to 1.5 heaping chashaku scoop, or about half a teaspoon) of matcha and approximately 75 ml (2.5 oz) of hot water per serving, which can be whisked to produce froth or not, according to the drinker's preference (or to the traditions of the particular school of tea
Schools of Japanese tea ceremony
"Schools of Japanese tea ceremony" refers to the various lines or "streams" of the Japanese Way of Tea. The word "schools" here is an English rendering of the Japanese term ryūha .-san-Senke:...

). Usucha creates a lighter and slightly more bitter tea.

Koicha, or thick tea, requires significantly more matcha (usually about doubling the powder and halving the water): approximately 3.75 grams (amounting to 3 heaping chashaku scoops, or about one teaspoon) of matcha and approximately 40 ml (1.3 oz) of hot water per serving, or as many as six teaspoons to 3/4 cup of water. Because the resulting mixture is significantly thicker (about like liquid honey), blending it requires a slower, stirring motion which does not produce foam. Koicha is normally made with more expensive matcha from older tea trees (exceeding thirty years) and thus actually produces a milder and sweeter tea than usucha; it is served almost exclusively as part of Japanese tea ceremonies.

Basic matcha teaware

For the Japanese tea ceremony the list of tea ware is large but just for the making of Matcha is actually not difficult and doesn't require much equipment.
Tea bowl (茶碗, chawan) – large enough to whisk the fine powder tea around 4 ounces.
Tea whisk (茶筅, chasen) – a bamboo whisk with fine bristles to whisk or whip the tea foam.
Tea spoon (茶杓, chashaku) – a bamboo spoon to measure the powder tea into the tea bowl. Not the same as a “teaspoon” of British tea culture.
Tea caddy (棗, natsume) – container for the matcha powder tea.
Tea cloth (茶巾, chakin) – small cotton cloth for cleaning tea ware during the tea ceremony.

Health Benefits

The health benefits of green tea and matcha have also raised significant interest in North America and indeed the rest of the World. Consequently, it can now be found in numerous health food products ranging from cereal to energy bars. In 2003, researchers from the University of Colorado found that the concentration of the antioxidant

 available from drinking matcha is up to 137 times greater than the amount of EGCG available from other commercially available green teas.
Matcha is also said to boost metabolism and help reduce cholesterol levels when drunk regularly.
The aforementioned health benefits of matcha green tea can largely be attributed to the fact that the whole tea leaf is ingested, as opposed to just the steeped water in the case of 'bagged' green teas. This means that it delivers a much higher potency of catechins, chlorophyll
