Kombucha – The Beginnings

Raspberry Kombucha

While at lunch on day, a coworker had a bottle of Kombucha and I asked her for a small sample.  I loved it.  Honestly, if you don’t like sour, vinegary, tart, slightly fermented flavors, I suggest you discontinue reading this piece.

I like kefir, buttermilk, sour cream, sauerkraut, sour pickles, and other food items that can be made using fermentation.  In all sincerity, most of us know that these foods were once created by natural fermentation are now processed and produced in mass quantities. Food in general is not nearly as healthy as they used to be back in the day.

So, while at Fresh Market, my wife Cat and I picked up a few bottles of commercially prepared kombucha. One was a ginger flavored bottle and the other a cranberry flavored one.  The are especially good when cooled and very effervescent.  Probiotics are all the rage now and kombucha also called “booch” by enthusiasts and are rather easy to make.  There is a little bit of SCOBY at the bottom of most bottles.  A SCOBY is a Symbiotic Culture (or Community) Of Bacteria (beneficial, of course) and Yeast.

SCOBY – Symbiotic Culture Of Bacteria and Yeast

When creating my most recent home brewed beer that I saw kombucha SCOBYs in the local brew supply shop.  They were in a large jar stacked together. It`s called a SCOBY Hotel (no joke). So, I ventured down to the brew shop and asked to purchase one.  I later learned that purchasing a SCOBY of size is only necessary if you wanted quicker gratification in making your own.  You can start your SCOBY from a commercial jar of plain, raw Kombucha, some black tea, non-chlorinated water, and plain white sugar.

The proportions for making 1/2 Gallon of the sweet tea are:

  • 1/2 Gallon Non-Chlorinated Water
  • 1/2 Cup Sugar
  • 4-6 Bags of Black or Green Tea (or mix is fine)

I prepared a 1/2 gallon batch of sweetened tea which cooled to room temperature.  I added the SCOBY to the tea which was in a 1/2 gallon pickle jar which I previously cleaned and rinsed in white vinegar.  I did not have any kombucha starter since this was my first batch, so I added about a 1/2 cup of white vinegar.  This is added to make the solution more acidic which inhibits undesired microbial growth.  I then added the SCOBY and a little of the kombucha liquid into the room temperature tea.  I placed a coffee filter over the top of the jar and secured it with a rubber band.  I waited 8 days tasting the tea each day after the 5th day of fermentation.  The kombucha tea can sit and ferment for up to 30 days without any negative effects on the SCOBY.  The longer you allow it to ferment, the stronger the vinegar taste and less sugar.

Since this was my first brew, I waited only 8 days and bottled it in flip-top bottles. I made one bottle of plain unflavored kombucha and added about 1/2 cup of apple-cranberry juice to the other bottle.  These were 1/2 liter bottles.  I place to wait 1-2 weeks before refrigerating.

Here are the next batches of 1/2 gallon Kombucha brews:

“Get Down” Brown Ale – All Grain Recipe

BROWN ALE (All Grain)

Roasted malt, caramel-like and chocolate-like characters should be of medium intensity in both flavor and aroma. American-style brown ales have evident low to medium hop flavor and aroma and medium to high hop bitterness. The history of this style dates back to U.S. home brewers who were inspired by English-style brown ales and porters. It sits in flavor between those British styles and is more bitter than both.

SMASH Beer Brew Day

October is a great time to brew home-made beer.  This particular brew was more cost-effective than any brew I have undertaken.  After tasting the wort (unfermeted beer), the Cascade hops (a very healthy dose) came through with flying colors as the taste was unmistakably hoppy” with a nice, semi-sweet maltiness.

This is an authentic “local” beer, with 12 ounces of whole Cascade hops that I grew and Athens filtered tap water.  The malt and the yeast were purchased.

Get the carboy clean and sanitized.  This is a “Mark’s Keg Washer. A 30-45 minute wash using Powdered Brewery Wash and another using Star-San makes the carboy squeaky clean.

IMG_1603

Bring 8 gallons of water to a boil.  It’s better to have too much mash and sparge water than not enough,

IMG_1604

Get all the brewing gear ready.  having the right utensils, thermometers, tubing, and other materials and tools make all the difference when brewing.  It can make the difference between a lot of hard work and a fun and fulfilling production of good beer.

IMG_1605

Cascade hops ready to use. I’ve been harvesting these off and on all summer and early fall and putting them in the freezer.  Fresh would be best; however, frozen works well and is about the next best thing.

Pre-heat the mash tun with hot water.

IMG_1607

Start stirring the grist into mash tun – start watching temperature closely. Today is a nice day with relatively stable outdoor temperatures.  So, the water and mash temperatures did not vary much at all.  It was a very pleasant fall day here in Athens, Georgia.

IMG_1608

Mash temperature stabilizing at 155F degrees – target was 152F degrees

IMG_1609

Put hops in the bag ready fro the boil – 12 ounces in total and I used them throughout the boil

IMG_1610

After an hour of mashing, temperature still stable at 155F degrees – ready to sparge

IMG_1611

Start sparging (rinsing) the mash into the liquor pot – I use a simple stainless steel strainer and pour the 170F degree water over the grains as the wort drains into the liquor pot.  It is best to add sparge water slowly to get all of the sugary wort drained out of the mash tun.

IMG_1614

Sparging essentially stops the chemical conversion and rinses all of the wort to be gathered in the boil pot.

IMG_1620

The start of the “hot break” when the water comes to a boil. A foam appears temporarily when the boil begins.  I turn the heat down and take the excess sugary foam out and stir until it settles down.  Then, I turn the flame back up and continue with a rolling boil.

Adding the hops bag to the boil – you begin to smell the hops aroma almost immediately.  The hops addition for this was for 3 ounces of hops.  I steeped 12 ounces to punch the hops acidity up.  This will be one of my “hoppiest” beers.

During the final minutes, drop the Irish Moss tablet (WhirFloc) to the boil.  Allow to dissolve and then add the copper wort chiller coil to the wort and allow it to sterilize.

IMG_1624

Carboy is nice and sanitized and ready for the wort.  Once the wort has cooled, it is transferred to the carboy.  It is during this time that precautions to keep things exceptionally clean and sanitized lest any contamination creep in and spoil your beer.

IMG_1627

Initial gravity reading at 1.035. This number is used with the reading taken once the wort has fermented and becomes beer.  The 2 numbers allow you to calculate the Alcohol By Volume (ABV) as a percentage.

IMG_1628

Carboy ready to receive the wort from the boil pot. Note that a sanitized airlock is inserted into the carboy to keep out any airborne contaminants.

IMG_1631

Start the siphoning process called “racking” to the carboy – yeast starter in flask inside of blue bucket ready to add after the racking is complete.  A yeast starter is actually a very small beer of sorts.  It has dried malt extract and water that has been boiled and cooled to 68F degrees. Yeast is then added to it.  A stir plate is a nice device that helps keep the process active.  it takes from 12-18 hours for a yeast starter to complete.

Here comes the wort

Nice looking wort that will soon be fermenting as the yeast begins its work
