More reasons to brew kombucha

Have you heard about kombucha?  It is a fermented tea.  I read that it originated in China and other parts of Asia over 2000 years ago.  


To brew it, you will need:

-water
-tea
-sugar 
-SCOBY (Symbiotic Colony Of Bacteria and Yeast) pellicle with kombucha (the starter tea) 

A new batch can be brewed with just the kombucha as starter tea as the SCOBY culture is present in it but it will take a longer time to ferment without the pellicle.  The SCOBY pellicle is usually supplied with kombucha.  However, if you only have the pellicle, you can use two tablespoon of distilled white vinegar to replace the kombucha as the starter tea. New SCOBY pellicles will form as a by-product of the fermentation process.  

I became interested in learning about kombucha when I found out that the SCOBY pellicles used in the production of kombucha can be dried to become a leather like fabric that you can use as art and craft material.  Watch this video to see how the material can be created with kombucha.


As shown in the above video, you can make SCOBY pellicles in petri dishes:
-by pouring two tablespoon of kombucha (must be unflavoured starter tea) into each dish.

If your intention is to make art and craft material with the SCOBY pellicles produced, you can: 
-add colourings of your choice to each dish.
-leave them to ferment for 2-3 weeks till pellicles are formed.
-check thickness of pellicles.
-when thick enough, take them out of the dishes to dry under the sun for a day.
-bring them in to air dry in a well ventilated area.

You can start crafting with them when they are dry.  As to what you can make with them, check out videos shared at GiY: Bio Buddies.  I like how they were able to make lanterns with them.


Other than that, why should anyone take the trouble to brew kombucha?  Based on my research, it is a beverage filled with:

-amino acids
-vitamins B
-vitamins C
-minerals
-antioxidants 
-probiotics

Drinking it regularly will:

-boost immunity.
-enhance mood.
-fight allergies.
-detoxify and defend body of infection and disease.
-detoxify liver which will put you in a happy mood.
-increase metabolism.
-improve digestion.
-rebuild connective tissue. 
-helps with arthritis, gout, asthma, rheumatism.
-cancer prevention
-reduce glucose levels.
-aid healthy cell regeneration.  

The tea you buy to brew kombucha should be organic as you do want them coated in pesticides which can inhibit the fermentation and brewing process and can eventually kill your SCOBY.  These are the type of tea you can use:

-pure black tea (reported to make it much more flavourful).
-green tea
-white tea 
-oolong tea 
-hibiscus tea
-a blend of the above

You should avoid using teas:

-that are scented or flavored teas which can effect the growth of your kombucha culture.
-like Earl Grey that will introduce naturals oils as they float on top and suffocates the SCOBY.
-like Chai which contains cinnamon, cloves and cardamom, all of which have antibacterial properties, that will kill the SCOBY.
-that are herbal like peppermint or chamomile as they will not be able to provide the nutrients necessary to feed your kombucha culture. 

Do not start the process till you have the following utensils on hand:

-stock pot or sauce pan
-long *wooden spoon

-glass jar with a wide opening to ease adding or removing SCOBY pellicles in size of: 
1/2 gallon or 2 quarts (64 oz / 1.9 Liter) glass jar - 2 units 

-Tightly woven cloth to cover the jar like:
clean napkins or
tea towels or
coffee filters or
paper towels

-Airtight Bottles:
Six 16-oz glass bottles with plastic lids or
swing-top bottles or
clean soda bottles

-Small funnel to ease pouring into bottles

*Note: prolonged contact between the kombucha and metal both during and after brewing can affect the flavor of your kombucha and weaken the SCOBY pellicles over time.

To start, wear a pair of gloves and spray Isopropyl Alcohol (IA) on the utensils you will be using:

-spoon
-sauce pan
-jars
-funnel
-cookie tray work surface (if you are also making kombucha leather)

Here are the steps based on all the articles I have read about brewing kombucha.


If you still have doubts about your ability to start, you can watch this video I found on You Brew Kombucha Youtube Channel as the brewer shares a lot of answers to questions that you are most likely to ask as you start brewing your own kombucha. 


You can also learn from Raw Brewing on how to start a Kombucha Brew Log so you can record the processes correctly.  It will help you nail the acidic flavour that you prefer best for your kombucha.

Once you have started brewing your own kombuca and have a collection of pellicles in your SCOBY hotel, check out this article:

Edible Water Bottle

"Containers" for drinking water from Skipping Rocks Lab are made of plants and seaweed which makes it possible for you to swallow it, with the water, whole.



Since, they are biodegradable, I wonder if it will be possible to leave a few blobs to water plants in my garden while I am away on a holiday.

Green enough to re-use bath water?

If being environmentally friendly means re-using your bath water, would you?  It may sound gross to anyone, but if you can get yourself a Hotaru, why not?

With a Hotaru you can even shower anywhere you want as it is a portable pop-up nylon tent set up over a plastic base that holds about five gallons (20 L) of water.  As an added plus, there is a purification filter in its base to clean up your dirty soapy water good enough for you to use it again.

If you use it on a camping trip, the unit needs to be connected to a car's cigarette lighter which will provide a shower of cold water.  If you need hot showers, you will have to use it where there is a power outlet or a generator to plugged it in to.

The filters are expected to last about two months and there is a built-in sensor to let you know when it is time to change them. Just remember to use mild body cleansers.

Check out how it looks in action.



Currently, the unit weighs 32 kg but founder, Ryo Yamada, says they are working to reduce it.

Plastic bottles? Light for some!

Every problem has a solution.  Sometimes you find them in the most unlikely way.

Illac Diaz, created a way for poor people, living in windowless, closely built homes in slum areas to light up their homes with plastic bottles.

The plastic bottles are filled up with water with bleach added to prevent any formation of bacteria.  The idea is that water inside the bottle refracts the sunlight during the daytime and creates the same intensity of light as that given out by a 55 watt light bulb.

Light from a bottle of water?  Check out to see if it really works.



If you are interested to make yourself one, watch this video.



You can also find the free tutorials at instructables.com. 

Share this idea if you think it could help your community.

Water? Before you drink...

I have written about why we should be concern when we are drinking or eating out of plastic containers.

No water? What would you have to do?

Actress, Jennifer Connelly, shows what she would have to do if there is no drinking water in New York, where her family lives.



You do not have to be famous to highlight the efforts of Charity: Water. Take a leaf off members of Twitter.

On 12 February 2009, members from Twitter community in 202 cities around the world held "Twestival" and raised USD250,000 (and still counting) for Charity: Water. That equates to clean water for just over 17,000 people living in Ethiopia, Uganda and India.

You don't have to crack your head for ideas on what you can do. Just visit Twestival or Charity: Water.

So, how did I come to know of this? My Twitter friend, Oiver Ding, emailed me a video of Twestival in New York he attended.

He even wrote about it in Mandarin on www.TEDtoChina.com. Way to go, Oliver.

Tap water. Taken for granted.

When water is always available at a turn of the tap, we tend to take it for granted. Here are some facts to help you review your usage.



If you wonder if it is likely possible that 80% of all sickness in the developing world is due to water-related disease, think about what could possibly make water too dirty for safe consumption. Think; as the population increases with industrialization and development where do the human, animal, and chemical wastes flow to?

As eco-conscious as a...

First you have to be aware about the amount of water you are actually using based on the stuff you opt to have in your life, be it for your physical or mental growth or well-being.

Save water? Found a way.

Do you feel that your children do not value water? Note that they are when they do one of the following:

1) Take long baths.
2) Don't turn off the tap properly.
3) Don't finish the water in their school containers.
4) Play water when they should be cleaning or watering the plants.

As soon as you see one of these signs indicating that they have taken water for granted, "shock and awe" them with this video.



You never know, they may be inspired to create their own version of "Watercone".

Water sources? Not from taps only.

I read with interest that occupants at the D’ Cempaka residential area are getting their water free. Are they stealing from the public water utilities? No, they are just occupants who bought homes with water tanks fitted to collect rainwater. Since it rains all year round in Malaysia, that is a very smart move.

Why use treated water to flush your toilet, wash cars, water your plants or do your cleaning up when you can collect rainwater from the environment? So, is rainwater the only source of supply for free water you can tap on?

If you answered yes to that, then you ought to take a look at the lists of possible sources of water from the environment posted on:

Wilderness Survival.

So, look around you. Are you living near one of these sources? I think the children would enjoy working on building gadgets to procure water that they can pick up from Wildwood Survival:

Plants

Wilderness

Tree through transpiration

Can we drink water from such sources? Now that is very ambitious. You need to learn some water Purification Processes.

What if the odour of the water from these sources is too strong to swallow? Add charcoals to the container of water and let it stand for 45 minutes before drinking. Picked that up from a free eBook, "Life and Death Matters: Must Have Water" by Discovery Channel.

Talk about being ambitious; Singapore beats us to it again. To curtail their reliance of buying water from Malaysia, they are recycling wastewater or sewage water. So, when you are down in Singapore and want to do the "being there done that" thing, make sure you buy a bottle of their "safe to drink" NEWater.



May be psychologically hard to swallow but this treated sewage water is, in fact, cleaner than the other sources of water in Singapore. So, who said that one cannot make money from waste?
