Recent studies have shown some of the effects of tea on brain function.
- A recent human study examined the effect of the unique tea amino acid L-theanine on attention related task performance. Task performance was measured by tracking electrical activity produced by the brain ( via EEG). The results suggest L-theanine plays a role in processing attention in synergy with caffeine. (1)
- A published randomized human clinical trial found that subjects given a daily supplement with green tea extract and L-theanine extracted from tea experienced improvements in mild cognitive impairments (MCI). (2)
- Caffeine and L-theanine in tea may offer cognitive benefits and improve mental clarity and work performance. A cross-sectional study showed that participants who consumed more tea felt less tired and reported higher levels of subjective work performance. (3)
- A double-blind, placebo controlled crossover study showed that the flavonoid EGCG (found in green tea) was associated with a significant increase in self-rated calmness and reduced self rated stress. This is in keeping with the widespread consumption of green tea for its purported relaxing/refreshing properties.

Here are a few examples to get you started:
White tea is subtle so pair it with light tasting foods such as vegetables and white chocolate.
Green tea has a light vegetal/grassy taste so pair it with mild fish or chicken. Salads are also a good choice as is simple fruit like melon
Oolongs are more complex and cover a range from light (closer to green tea) to more oxidized (closer to black tea). Try a lighter oolong with seafood or cheese and crackers. Use a more oxidized oolong with grilled salmon or smoked meat
Black tea is more robust and can be paired with spicy foods. Flavored black teas also do well with a sweet dessert.
Follow link to a great chart from the Tea Association of Canada with even more ideas on how you can pair teas with food! Enjoy.
Energy efficient and simple, cold steeped teas have less bitterness and less caffeine. Unlike "sun tea", where you leave your tea in the sun to brew, there are no food safety concerns with cold steeping. Cold brewing also brings you a cleaner, less astringent cup. Any type of tea can be used but green , white and oolong teas produce the best cups. Herbal fruit teas also do well. Experiment with your own favorite and let us know!
To make cold steeped tea simply add one teaspoon of loose leaf tea per cup of fresh cold water, place in a suitable container and leave in your fridge overnight (at least 8 hours). Strain out the leaves and enjoy!
All tea comes from the Camellia Sinensis plant. The difference is in how much the leaves are oxidized and processed after they have been plucked. During the oxidation process the leaves undergo chemical reactions that result in the variations of taste and colour. Heating stops the oxidation process.
There are 4 main types of tea:
Green tea may be rolled or processed and then heated quickly to stop oxidization before it truly begins to happen.
White tea is left to oxidize for a very short period before heating. White tea is usually not processed at all.
Oolong tea is partially oxidized and has some of the characteristics of both green and black tea. Oolong leaves may be rolled or twisted. Oolong are very aromatic and full of flavour.
Black tea is the most common type of tea in North America. It is fully oxidized and results in a full rich flavour and amber liquor.
Herbal teas are not made from the Camellia Sinensis plant but are infusions of herbs, leaves, flowers, fruit or other plants.
Tea Storage 101: Or how to make your quality loose leaf tea stay as fresh as possible for as long as possible!
Resist the temptation of storing your tea in a clear glass or plastic container, light will degrade your tea quickly.
Keep your tea in your pantry or cupboard and away from any heat source such as your stove or toaster. There is some evidence that storing tea in your refrigerator or freezer can extend the life of your tea, however, be sure to let the tea warm up to room temperature before opening as the cold leaves will attract moisture and degrade your tea. As with any other organic matter, tea, when wet, can create mold and ruin the taste of your cuppa!
Store your tea away from spices or other strong odors. Tea (especially green tea) will take on any odors that it is exposed to.
Keep these tips in mind when you store your tea and you will have the best tasting tea with ever cup!
Legend has it that tea was first discovered by the Chinese Emperor Shen Nong, who was boiling water for drinking one day in 2737BC when a tea leaf happened to fall into his pot. By the time of the Shang dynasty (1766-1050BC) tea was being consumed in Yunan for it's medicinal properties.
Tea spread to Japan around 1191 when a Zen priest brought tea bushes to Japan and planted them in Kyushu. It was not until the seventeenth century that tea was introduced to Europe by the Dutch. Only green tea had been consumed until this time but it was found to spoil easily on the long trip tin damp ships to Europe. The Chinese realized that if the tea were darkened, fired and bake dried it would survive the trip without spoiling. Thus black tea was introduced to the western world!
