The Mother of All Libations

Bottles of Russian mead.

Until the 12th century, sugar was not a common ingredient, although it had been extracted and refined for a couple thousand years.  Honey was the common sweetener, and was used medicinally and as a preservative as well.  Honey, mixed with water and perhaps a grain mash, then fermented, is the oldest known fermented drink.  Its origins are lost, but there is archaeological evidence of fermented drinks.  Science Daily reported in 2004 that pottery jars found with the remnants of a fermented beverage made of rice, honey, and fruit show that it was produced in northern China 9,000 years ago.

Honey, the basis of mead.

This drink is called mead, and the very word attests to its ancient heritage.  The word comes from the proto-Indo-European root *médhu, and it has an interesting range of meanings in Indo-European languages which all have to do with honey, sweet, intoxicating, or drunkenness.  The earliest surviving written mention of it is in the Rig Veda, the ancient Indian collection of Sanskrit hymns (1700-1100 BCE). Aristotle (384-322 BCE) wrote of it in his writings.  Columela, who lived in the first century CE in Roman Hispania and wrote on agriculture of the area, recorded the following recipe:

Take rainwater kept for several years, and mix a sextarius
of this water with a pound of honey.  The whole is exposed
to the sun for 40 days, and then left on a shelf near the fire.
If you have no rain water, then boil spring water.

Mead can be found in literature, especially Celtic.  In Beowulf (circa 8th-11th century CE), warriors drink mead.  About 550 CE, Taliesin, a famous bard, wrote "The Song of Mead".  But in Norse mythology, there is the Poetic Mead or Mead of Poetry, also known as the Mead of Suttungr.  This is a mythical drink that renders anyone who drinks it a scholar, able to recite lore and answer any question.  This was a metaphor for poetic inspiration, said to have been created from the gods spitting in a vat.  They created a man from this spittle who was so wise he knew everything.  Two dwarves killed him and mixed his blood with honey, creating a mead that transformed anyone who drank it into a scholar or a poet.  (The dwarves told the gods that the man had suffocated in his own intelligence.)  Such is the stuff of legends and drunks!

Mead was the historical beverage of preference, until heavy taxation and regulations of the ingredients in alcoholic beverages caused the commercial production of it to significantly lessen.  However some monasteries, especially those in areas where grape production (and hence winemaking) wasn't feasible, engaged in making mead, although it was often a by-product of beekeeping.

A Polish mead, called Trójniak.

In Central Europe and the Balkan area, mead has always been popular.  The Polish name for it is miód pitny, or "drinkable honey".  It also remained popular in Russia, and is mentioned in the works of Tolstoy, Dostoevsky, and Gogol.  The Finns make a sweet mead spiced with lemon, then raisins are added in a second fermentation.  In Africa, Ethiopians drink tej, flavored with a species of buckthorn, and traditionally served in a rounded container called a berele.  There is a mead called iQhilika made by the Xhosa of South Africa.

Since honeys have so many different flavors, so do meads.  Taste also depends on the yeast used or created during fermentation, and the aging process.  In ancient times, meads were fermented by wild yeasts or the bacteria from the skins of fruits, but since these are so unpredictable, yeasts have been developed for use that preserve the honey flavor.  Additives, known as "gruit", also enhance the flavor. Some types of gruit are a combinations of herbs, seeds, and berries.  Others are a mix of fruits and spices.  The blending opportunities are endless, and making mead at home is enjoying a revival, especially since commercial meads, although more prevalent, can be hard to find.

Two types of Finnish mead, on the right is rhubarb-flavored.

There are a plethora of variants of meads.  Meads that contain spices or herbs are called metheglin.  If a mead contains berries, it is a melomel.  This was also a good way to use up summer fruit, in effect preserving it for the winter.  A mead made with fermented grape juice is pyment.  Bochet is an interesting mead where the honey is caramelized before added to water, giving a toffee flavor to it.

Homebrewed melomel.

There are wines made with honey, but these are not considered true meads, and are in fact called faux-meads.  Hypocras, is a drink made with wine, sugar, and spices (mostly cinnamon), which is strained.  It was popular in the Roman Empire, and highly prized in the late Middle Ages, and even inspired the Spanish to make Sangria, originally made with cinnamon, ginger, and pepper.


So, if you are looking for a hobby and are interested in starting a meadery, you will find plenty of help online, from supplies to advice.  What a great way to keep the past alive, and perhaps your mead will, like the Mead of Poetry, enlighten your fellow human beings.

You say tea mold, I say kelp tea

Kombucha is a fermented drink with a tea base that has been claimed for centuries in many cultures to have health benefits, mainly as a digestive aid and a way to detox.  Because it is acidic and mildly alcoholic (no, you won’t get drunk on it), it is thought to be antimicrobial.  It’s been proven effective in animal studies, although there are not yet any known human studies.

It is also sometimes called "mushroom" tea, though it doesn’t contain mushrooms.  This name comes from the starter, which is a mass of beneficial yeasts and bacteria forming a cluster.  There are many names for this starter, SCOBY (Symbiotic colony of Bacteria and Yeast) being the more scientific one, and “the mother” being the more common one.  In Russia, where the first recorded history of kombucha exists, it is called “mushroom” or “tea mushroom”.  It is popular in Asia, where the Japanese make it with dried kelp, or kombu, and who gave it the name kombucha, which in Japanese means “kelp tea.”  The Chinese use three words for it, “red tea fungus/mushroom”, “red tea mushroom”, and “tea mold”.  Red tea is simply their interpretation of what we call black tea.

Kombucha tea is not too difficult to make, and much cheaper than buying it if you are a kombucha drinker.  Here’s what you need to make your own:

Tea
Sugar
Starter (store-bought, or from another tea)
Large food-grade glass container with wide mouth
Small glass bottles for pouring the finished product into
pH test strips
Cheesecloth or coffee filters with string or rubber band
Funnel for pouring finished product into bottles

Any type of tea may be used: black, green, oolong, whatever your preference. (Note: "herb" teas are not considered teas for this purpose.) Teas containing oils may require more fermenting and should probably be avoided until you are a "kombucha master." You can use organic cane sugar or refined white sugar. I have not tried honey myself, but a friend who uses it says it takes much longer to brew it using honey.

Like brewing anything, special care must be taken to ensure that you are working in a clean environment with clean utensils (and hands!), using the proper temperature. Care must also be taken to use a low pH factor (between 2.5 and 4.6), as a higher factor could lead to contamination and a lower one will make the tea too acidic. You can use distilled vinegar to control the pH factor. Start with an eighth of a cup. You should test at the beginning and end of the brewing cycle.

Start with about three quarts of boiling water. Add 4-8 tea bags (I prefer strong tea myself, but the choice is yours.) Remove from heat and add one-cup sugar. Once the tea has cooled to room temperature, pour into a food-grade glass container, add the starter, and cover with cheesecloth secured with a rubber band (you can use a coffee filter in a pinch.) Let the tea ferment for one to two weeks - the longer you let it ferment, the sourer it will taste. Make sure it is in a warm place, but not in direct sunlight. You will see a culture develop. Sample by taking a small amount out of the container - do not drink from the container itself! Once it has reached the taste you prefer, remove the culture with very clean hands or preferably clean rubber gloves and place into a clean bowl with enough liquid to keep it moist. Strain the liquid and bottle it. At this point you may add flavorings or fruit (rosehips is tasty!) Let it sit at room temperature for a week to allow the yeast to carbonate the liquid. Capping the bottles tightly will aid the carbonation. Once it is ready you can refrigerate the bottles.

You may want to start a new batch with a small amount of liquid from this batch, which will aid in keeping the pH factor low. Thoroughly clean the food-grade glass container and start the process again, using freshly brewed, sweetened tea and the culture you removed.

As its popularity increases, one can find commercial kombucha more easily, and with a variety of flavorings.  I hesitantly bought a bottle recently that was ginger-flavored.  It had a pleasant taste, and I’m hoping the ginger added to its health value.  Chocolate kombucha?  Nah, I’ll pass.
