Identification the quality of spring tea

According to the spring and the quality characteristics in two ways to tell.
The first is the dry look. Be judged on three factors from the dry tea color, smell, shape. Where a color of green tea Green Run, tea color zeu Yun, tea, fat and heavy real, or more pekoe and black tea, green tea, the cable tight knot, Gunpowder particles round and tight, and flavorsome, the quality characteristics of spring tea.

The second is the wet look. Open soup Review of tea, for further judgment. After brewing the tea, sinking fast, strong and lasting aroma, the taste of alcohol; green tea liquor color green was yellow, black tea liquor color Yan cash ring; the tea Securinega soft and thick, normal shoots more than in, for the spring tea.

The experts pointed out that due to caffeine, active alkaloids in the new tea and a variety of aromatic substances with higher levels of easy to make people excited, nervous system and the nervous breakdown, cardiovascular and cerebrovascular diseases have an adverse effect. In addition, the new tea oxidation of polyphenols and aldehydes content more strong stimulating effect on the gastrointestinal mucosa, gastrointestinal function, especially patients with chronic gastrointestinal inflammation, drink tea, could easily cause stomach pain, fullness, constipation, dry mouth symptoms. Therefore, the spring and the best place for some time, auto-oxidation of polyphenols in tea, gastrointestinal irritation lower after the drink.

The Storage of Green Tea

(1)Avoid wet: green tea is a porous hydrophilic material, so it has a strong moisture also moisture resistance. Storage of green tea, the relative humidity of 60% is more appropriate, more than 70% will be due to moisture absorption and mildew, and then acidified deterioration.

(2) Avoid high temperature: green tea best storage temperature is 0-5 ?. Temperature is too high tea in the amino acids, carbohydrates, vitamins and aromatic substances are broken down and destroyed, the quality, aroma, taste has been reduced.

(3)Avoid the sun: the sun will promote the oxidation of green tea pigments and esters, can chlorophyll is broken down into pheophytin. Green tea is stored in a glass container or a transparent plastic bag by the sunlight, its intrinsic material from a chemical reaction, so that the deterioration of the quality of green tea.

(4)Avoid oxygen: green tea chlorophyll, aldehydes, esters, vitamin C and so easy to combine with oxygen in the air, the oxidation of green tea tea make green tea liquor color red, darken, greatly reduced nutritional value.

(5) to avoid odor: containing polymer Palm enzyme and dilute terpene compounds in green tea. Such substances naturally live wave of extremely unstable, widely suction odor. Therefore, tea and smell articles mix storage, it will absorb the odor and can not be removed.

Professional save
Divided into two types of professional and family according to the different objects and green tea have and save, green tea preservation and storage methods, professional save merchants over their tea saved, the family is a small amount of green tea preservation, including green tea professional save in three ways:

(1) lime block Preservation Act. Quicklime block mounted on the white muslin bag. Green tea is loaded white tissue paper bag, coat brown paper bags, and small mouth pottery jars dry cleaned, Xiadian White, green tea tea bags in a small mouth pottery jars, in the middle embedded in twelve lime bags. Sealed with several layers of quality of the grass the altar, and the final compaction of the bricks and mortar or the thick woodblock in order to reduce the amount of air exchange. Since then we should always check to save the situation, the timely replacement of lime deliquescence.

(2) carbon storage method. Basically the same method of operation and lime block Preservation Act. With the material but extinguished with burning charcoal, Sheng tea utensils can be replaced with an earthen jar or a small mouth tin bucket. Increase or decrease the visual size of the container of the capacity of the charcoal bags and green tea, tea bags.
(3) green tea frozen method. Tea drying water vapor, moisture content between 3-5%, not more than 6%. Green tea into the aluminum composite bag, heat sealing, breathing air pump out of the air bag at the same time into the nitrogen, sealed seal affixed, placed on the tea box, and then into the low-temperature cold storage preservation. This method is the best tea in the conditions of the current technological level Preservation Act. Save a large amount of a long time.

Family save green tea
Green tea family preservation method, in general there are five:

(1) crock Chu Tea Act. This method is ancient times. Ming Feng Meng Zhen <fast Xue Tang Man recorded saying: "real tea urn, the bottom set Ruo, cementing upside down, over the summer is not yellow, its gas is not compromised." Tea water content can not exceed 6%. Available lime dehumidification. To do the same lime block Preservation Act.

(2) canning. Container selection loaded pastries or other food, listen to metal, boxes, cans, boxes, or iron or aluminum or paper or paper products, or square or round or flat or irregular. The important thing is that the tea should be dry, seal the bag. This method is simple, take the same convenience.

(3) plastic bag storage Tea Act. Selection of high-density, high pressure, thick, good strength, no smell of food packaging. The tea can be pre softer net wrap, and then placed in a food bag, seal Serve.

Thermos receptacle Tea Act. Available insulation is poor and abandoned thermos filled with dry green tea covered cork, sealed with wax.

(4)Refrigerator France. The high density of green tea is loaded, high pressure, thick, good strength, no smell of food packaging bags, and then placed in the freezer or freezer. This method to save time, the effect, but the bag must seal securely tight seal, otherwise it will resurgence or odor, but detrimental to the quality of green tea

How To Grow Tea

I’m obsessed with the idea of growing my own caffeine!  I’m addicted, there are no two ways about it.  And I really love my coffee and tea.  But it’s not grown locally, to be sure.  I ordered seeds last year, but we moved right after I planted them.  And they never came up.  So this weekend, I bought a seedling to plant with my mother’s ornamentals.  As a camellia, it should fit right in!

I thought I’d share some of the research I did last year about growing tea….

Types of Tea


Green TeaBlack TeaOolong Tea and White Tea all come from the same plant.  Surprise!  They all come from the leaves of Camellia sinensis.  There are two different varieties of the plant:  Sinensis sinensis and sinensis assamica.  The former has smaller leaves and thrives in cool, high mountains (eg, central China and Japan); the latter is a much taller plant and thrives in the lower elevations of moist, tropical regions (eg, Northeast India, and the Szechuan and Yunnan provinces of China).  There are also hybrids of the two varieties.

Picking Tea

Where Does It Grow?


Camellia sinensis is indigenous to China, Tibet, and northern India.  The major tea growing regions today include India, China, Sri Lanka, Japan, Taiwan, Kenya, Turkey, Argentina, Tanzania, Malawi, Zimbabwe…. and more.

That said, you can grow it outdoors in Zone 8 or above.  Or if you’re colder than that, you can grow it in a greenhouse or a pot that you bring indoors in the winter.  They’re a camellia, so if you grow camellias, chances are you can grow tea!

What Does It Look Like?


The fragrant flowers are white with yellow stamens inside (above).  The leaves are shiny and dark green, with new growth being much lighter. The fruits are small and hard, looking similar to a hazelnut (below).  The seeds are about 1/4” in diameter.  The sinensis variety can reach a maximum height of 10 feet or so; the assamica variety (think Assam tea) are much larger:  up to 65 feet tall.  So, for a garden plant, you’re probably going to want to go for the sinensis.

How Do You Grow It?


Propagation


You can propagate tea from cuttings or from seeds.  According to the flier I received with my seeds from Whatcom Seed Company: “Sow seeds 3/4” deep in standard soil mix with coarse sand added.  Keep damp.  Ideal night temperature of 55F, day 68F.  High humidity and filtered sun.  Fertilize often.  Ideal pH 5-6.”

Cultivation


Plants should be placed approximately 3 feet apart in a sunny to semi-shaded area.  Plant them so that a house, wall, tree, or something else will protect them from strong wind.  They should be pruned back every four years to rejuvenate the bush and keep it at a convenient height.

Harvest


Tea plants have a growth phase and a dormant phase.  The dormant phase is in the winter, so as soon as shoots (“flush”) emerge in the spring, the new growth is plucked for tea.  In hotter climates, there may be several flushes per year.  The two uppermost leaves and the new buds are picked during each flush.

Here’s the tricky part for the home gardener: propagating a tea plant from seed is like propagating asparagus, rhubarb, or a number of other perennials from seed.  It takes time.  If you grow a tea plant from seed, it can take three years before your plant is ready to harvest.  So until then, think of it as an investment, and experiment, or just a nice plant.  If that sounds like too long for you, you can buy a plant or propagate from a cutting.

Given the right conditions, a tea plant can grow and produce for 50-100 years.  Wild tea plants have been found to be as old as 1,700 years.

Black Tea

I want to introduce the black tea for everyone.
Black tea is a type of tea that is more oxidized than the oolong, green, and white teas. Tea Ancestor in China, the world’s first black tea from China Fujian Wuyishan tea area tea grower invention, called” Lapsang souchong”. Belongs to the fermented tea, tea is tea leaves as raw material, after wilt, rolled ( cut), fermentation, drying and other typical refining process. Do because of their color and brewing tea in the red as a main tuning, named Black tea. More types of black tea, Qimen tea producing area is wide, the famous congou black tea, and tea is fragrant, in addition, from the introduction of China developed India, Sri Lanka tea is also very famous origin.

Generally, unblended black teas are named after the region in which they are produced. Often, different regions are known for producing teas with characteristic flavors.
Souchong tea is one of the oldest tea, but also other tea ancestor, other black tea are small tea evolved. It is divided into Lapsang and small mountains, all originated from Wuyishan region.
