1. Hydrochloride HCL
2. Sulfuric acid H2SO4
3. Nitric acid HNO3

Message in a bottle

Hello bloggers,

In wananga  we wrote a story about a message in a bottle here is my story look below

I was walking along a river near a big mountain and I looked at something in the river that looked like glass. So I followed it and I grabbed it. There was a bit of paper that looked like a map. So I grabbed it out of the bottle and it was a map and at the bottom it said “hello  this is a message  telling you that there is  a treasure so follow the map.” 

I got my friend Fred and then we started. There were two paths. There was one path that said  “short cut and there was one go the right way”. To be continued...

ginger beer

 Aim: I want to find out how to make ginger beer

research: 

    

Fermented beverages have been a staple of the human diet since practically the dawn of (recorded) time (or at least 9000 years ago).  Without modern refrigeration techniques, people sought other methods to preserve food and mitigate spoilage.  Fermentation is one of the ubiquitous methods of preservation utilized by all cultures.

Using naturally occurring bacteria and yeast to ferment native foodstuffs didn’t only protect them from spoilage, it also added pro-biotic food to their diet and boosted their nutritional intake. Not only that, many fermented foods contain enzymes humans need to more effectively derive nutrition from their food.  Whether they knew it or not, ancient peoples benefited in many ways from fermented foods.

Most people today are pretty disconnected from the natural world, especially the natural bacteria that are disinfected out of our lives.  In some cases, that is good.  Certainly nobody wants to catch the plague! However, I believe that our “war on bacteria” is at the root of a whole host of heretofore never before heard of “modern illnesses,” both mental and physical. As a society, we are severely out of (bacteria) balance. Correcting that balance is what fermented drinks are all about!

So, to that end, let’s take a look at a few interesting drinks from around the world.  Many of these are ancient beverages and their popularity throughout the ages demonstrates the power of fermentation.  It’s hot baby!

5. Sima

Sima is a traditional beverage of the Finnish people. It is made and served during Vappu, the Finnish May Day celebration. While normally a stoic people, Vappu is considered the one time of year that they really let their

hair down.  Like most May Day celebrations, its roots are from the Pagan tradition.

Sima is a quick and easy ferment (warning: pdf!) with lemons, sugar and yeast. The short fermentation cycle (of which the conclusion is indicated by raisins added to the bottling stage that float to the

top) reduces the amount of alcohol present.

While drunk by adults, it is also popularly served to kids, as many other cultures have more accepting attitudes towards low doses of alcohol for children.

4. Boza or Bouza

Boza is a traditional fermented drink whose roots have been traced all the way back to Mesopotamia, 8000-9000 years ago. It is mainly made from hulled millet, which is boiled in water and then poured into broad shallow pans. When cool, the mixture is strained through a sieve, and water and sugar are added.

Boza is produced in most Turkish regions and in Bulgaria, Albania and Romania. Bouza is produced in Egypt and is most likely the forerunner of beer in Ancient Egypt.

Different cereals (wheat, millet and rye) can be used for Boza production, and natural mixtures of yeasts and lactic acid bacteria cause fermentation. Starter from a previous batch is used and both lactic-acid bacteria and Saccaromyces (same yeast as in Komb…hold on. I don’t want to ruin the surprise of #1) are involved in the fermentation process.

3. Milk Kefir/Water Kefir (tie)

Those were interesting to read about – now let’s get to some more familiar fermented friends!  I LOVE Milk Kefir.  Its smooth and creamy and filling – a perfect snack. Though often referred to as drinkable yogurt, kefir is so much more.

Second Ferment Kefir

As I found out in the Top 5 Fermented Foods, many of the commercially available foods we assume would be fermented are not, or have been heat treated to eliminate most of the good bacteria.

Not surprisingly, most supermarket Kefirs are pasteurized and don’t provide the same level of health benefits as the homemade stuff. I recommend making it with raw milk to get the most bang for your buck.

Since milk gets a bad name these days, or if you happen to be vegan, water kefir is another option. A popular alternative has sprung up utilizing young coconut water instead of sugar. Again, a short fermentation cycle means low alcohol levels for those concerned. The beverage is lip smacking delicious.

2. Ginger Beer

This one is on my to-do list for sure.  I confess to totally digging on the Reed’s Ginger Brew, but just like the booch, that stuff gets expensive. Reading about how to make this version myself had my mouth watering, I was so excited. I’ve got to carve out time to make this recipe (and visit this cool site again).

It says: “The British Excise Regulations of 1855 required that the drink contained no more than 2% alcohol, and usually it was far less potent: hence ginger beer became popular with children.” That’s exactly the kind of classification Kombucha (and other fermented drinks) needs: less than 2% allows for health benefits without buzz, IMHO. Oops, I let my #1 drink slip! You never would have guessed…

1. Kombucha

Okay, so I am predictable, but what did you expect? You might look at others, even sample, but you always come back to the one you love. How about a special Kombucha fact, then? Something you’ve never heard before?  Okay, I have heard from multiple people that Kombucha can be left bottled for nearly as long as you want! In fact, after a full year, Kombucha is reported to taste smooth and delicious, not tart or vinegary as one might expect.

I’m not surprised, as I have found even 45 days or so produces somewhat the same effect, with a significant mellowing of the taste.  But, is that drink Kombucha, or has it become something less alive or pro-biotic, lacking in the vital acids? Testing is the only way to find out. Another project!

ingredients

Bug

Warm water
2 tsp active dried yeast
2 tsp Chelsea Raw Sugar
2 tsp ground ginger

Ginger beer
3 cups Chelsea Raw Sugar
2 tsp cream of tartar
1L boiling water and
5L cold water
Juice of 2 lemons, strained

method

Bug:
Fill a large glass jar ¾ full with warm water. Add the yeast, Chelsea Raw Sugar and ginger. Cover loosely with a lid or tea-towel – do not screw tight or it won’t be able to breathe. Sit in a warm place, such as the kitchen table or similar.  
Feed your bug every day for seven days with 1 tsp Chelsea Raw Sugar and 1 tsp ground ginger.
After a week, you are ready to make your first batch of beer.

Ginger Beer:
In a large bowl or bucket, put the Chelsea Raw Sugar and cream of tartar, then add the boiling water. Stir to dissolve the sugar before adding the cold water. Get your bug and pour all the liquid (not the sludge in the bottom) into a bucket and add the lemon juice.

Stir well and then pour into your clean bottles – it makes six 750ml bottles.

Store in a cool, dark place for two weeks before drinking. Make sure you open the bottle in the kitchen sink as it might overflow. Open the cap bit by bit to allow the air to escape.

RESTORE AND REUSE
Take the jar with the sludge in it and fill with water to the top. Tip out half or give to a friend so that they can make their own bug. Fill back up to ¾ and feed for another week.

DON’T NEGLECT IT
If you are too busy to make a batch of ginger beer one week, don’t just keep feeding and hope for the best, as your bug won’t survive. Pour it out after a week – as you would if you were making some ginger beer – and follow the above instructions for restoring your bug all over again.
