General Questions

Quality Matcha isn't just another type of green tea, it's the champagne of green tea. Matcha comes from the same plant as all tea, Camelia Sinesis but the way it is cultivated and processed is what makes matcha so special. Real matcha comes from Japan and is made from the finest shade-grown leaves stone-ground to a fine powder.

Translated from Japanese, matcha means "powdered tea". With regular green tea, which is infused in hot water, 85-90% of the nutrients are discarded with the leaves. However, with matcha, you're drinking the entire leaf so your body benefits from all the soluble and non-soluble elements of the tea first hand.

Matcha comes from the same tea plant (Camelia Sinensis) as all teas but about 4 weeks before it's harvested the Matcha tea field is shaded in bamboo (or a man-made bamboo equivalent), this special shading technique results in a 90% reduction of sunlight. The plants, now growing almost in the dark, compensate for the lack of light with an intense production of chlorophyll making the leaves rich in amino acids. The process encourages the chlorophyll to rise to the top and then at the time of harvest only the youngest most tender, emerald green leaves are picked from the top third of the bush.

After being steamed and then freeze-dried, the highest quality leaves are selected and the stems gently removed. The last step in producing our Matcha takes place in the factory where special granite stone mills grind the Tencha tea into superfine Matcha powder. The grinding itself is done in a cleanroom in which temperature and humidity are kept constant. Industrial quality air filters keep the air clean and eliminate bacteria and germs. One single stone mill grinds only up to 30-40g of tea per hour, which is the amount of one of our OMGTea Matcha tins. More rapid grinding would burn the leaves.

This very fine powder is mixed with water and drunk rather than being brewed and the leaves (or tea bag) discarded. This means you get all the benefits of the Matcha tea in every cup you drink - nothing is thrown away.

Yes all of our products are certified organic with Organic Farmers and Growers (OF&G).

OMGTea Matcha cultivation involves shading the plants with bamboo three to four weeks before harvesting. This process boosts the nutrient levels to of matcha to extraordinary levels.

The plants, which grow in near-darkness, compensate for the lack of light by producing an intense amount of chlorophyll. The leaves become packed with amino acids and the chlorophyll rises to the top, making the leaves a rich emerald green.

A Matcha rich and green in colour means that the leaves used were grown very well, with just the right duration of pre-harvest shading and other cultivation controls to encourage the plant to produce more chlorophyll. It tells us that the tea is rich in nutrition; higher in antioxidants and amino acids like L-theanine.

Yes it does but each ½ teaspoon serving (1gram) contains 34mg of caffeine, compared to 70-180mg for a cup of coffee. It is easily tolerated by most people for whom coffee makes them jittery this is because all of the other components that make up Matcha slow down the release of caffeine into the body. It usually takes three to six hours for this minimal amount of caffeine to be absorbed into the bloodstream; however the mental alertness and energy are apparent almost immediately upon drinking it.

The 'type' of caffeine in Matcha is different to that of caffeine in coffee, called Theophylline, which gives you a much more sustainable release of energy throughout the day.

In contrast to coffee, this timed-release mechanism tends to inhibit any sudden insulin increases, so there is no “crash” associated with quick drops in blood sugar that so many coffee drinkers feel an hour or so after drinking a cup. Nor does Matcha stimulate the production of cortisol, the stress hormone, as coffee can.

In other words, Matcha doesn’t give you that “wired” feeling. If you’re wary of caffeine, you can relax! And let Matcha help you relax!

So in a nutshell the combination of caffeine, phytonutrients, antioxidants and amino acids produces a fabulous effect on Matcha drinkers – the envious ability to be able to focus and be productive over an extended period of a few hours (for some, up to six hours). 

OMGTea comes from the Kagoshima prefecture and our award winning matcha is the pride and joy of our tea farmers. Kagoshima is on the southern island of Kyûshû, known for its lush vegetation and unspoilt landscape. The warm, humid climate provides the perfect conditions for growing matcha. Kagoshima is a volcanic island and as such has extremely nutrient-rich soils, at least eleven active volcanoes continue to provide the valuable minerals that help these extraordinary tea plants grow. Such optimum conditions enable the cultivation of the best quality organic matcha and it has been cultivated here for over 700 years. This long history and the ongoing optimisation of cultivation processes has made Kagoshima the second-biggest tea prefecture in Japan, specifically offering optimum conditions for organic matcha cultivation.

We run tests for heavy metals across our full product range on a regular basis and as a result of robust quality controls and laboratory analysis, we can guarantee that our matcha green tea is safe for consumption and does not contain any contamination of heavy metals outside of the legal limits. According to our General Specification we guarantee a value of no more than 5mg/ kg however in our analysis we detect around 0.1 mg / kg and in some cases the lead content is so low it is undetectable.

Furthermore, our matcha tea is 100% organic and produced in a sustainable way, so that the health promoting properties and taste are preserved.

Believe it or not, lumps are a sign of quality! At OMGTea we only use high-quality organic leaves that are gently and slowly stone ground to make sure the leaves are not burned and that the powder is fine.? This process not only ensures a smoother taste but it also ensures your matcha mixes better with water. The finer the powder however, the more prone it is to clumps. Clumps forming can be avoided if the matcha powder is sifted before adding water or if the clumps are broken down by whisking after you have added water.

To avoid clumps, we always recommend using a tea strainer which is made of very fine mesh. Simply hold the strainer over your mug or bowl and put the matcha through it before mixing and this will set you well on your way to making the perfect cup of matcha every time!

Due to Its caffeine content it might be advisable for pregnant women to avoid drinking Matcha, particularly in the first trimester. There are studies that suggest that 200-300mg of caffeine a day is a safe limit for pregnant women. A typical serving of Matcha has 30mg of caffeine.

The BBD for Matcha is usually 2-3 years (at OMGTea we set it at 2 years) if it’s kept in a dark, dry place at room temperature. The ideal way to preserve Matcha is of course to be refrigerated below +5C (41F) or fridge temperature after opening. The more it comes in contact with air and light, the faster the degradation.

Tins are the ideal packaging method for protecting and preserving Matcha tea. The tin is mechanically sealed air tight in Japan to ensure freshness; the lid is lined with a rubber sealant so that an airtight seal can be made again if the lid is screwed on properly. This ensures it is kept fresh as long as possible.

Definitely and probably the best alternative option for those addicted to coffee. Matcha gives an energy release 4-6 times longer than coffee, while also regulating blood sugar, meaning that you will feel both energised and content. The L-theanine effect relaxes and calms the nervous system, rather than over- stimulating it. Switch to Matcha and we can almost guarantee that you won’t need coffee to get you through your day. You might still like the coffee taste so go for de-caff as the coffee “hit” won’t be required anymore.

L-theanine (chemical name g-ethylamino-L-glutamic acid) is a rare, water soluble amino acid and has been shown in scientific and clinical studies to have a direct influence on brain activity, particularly reducing stress. It is found only in certain species of tea plants and most abundantly in Japanese Matcha. It was first discovered in 1949 and not only does it provide one of the important health benefits of tea, it is also the major flavour of green tea. 

L-theanine is responsible for increasing alpha brain wave activity, which in turn promotes relaxation. When combined with the stimulant caffeine it allows tea to induce a feeling of increased concentration over a longer period of time, compared to caffeine alone. This is because the effects of caffeine are being moderated by L-theanine.

Matcha has been used by the Zen Buddhist Monks for exactly these seemingly contradictory qualities. The timed release of energy by the caffeine and theophylline is at a rate that the body can deal with naturally (sustained 3-6 hours) while the powerful amino acid effect of the L-theanine relaxes and focusses. L-theanine encourages the transition from the beta brain waves of mental arousal to the alpha brain waves of relaxation. 

Since the Fukushima disaster, checking our teas for radioactivity has become a standard process. We mainly source our tea from cultivation areas in the Kyushu region in the southwest of Japan. These tea fields are more than 1,000 kilometers away from Fukushima. Since the incident we regularly analyze our products for radiation and all of our products are in the non-detectable area.

Matcha is naturally gluten-free. No colour or flavour enhancers, sugar, or anything added. Just pure Japanese organic matcha green tea.
