irondance vodka : the pot still and kitchen science

 i always wanted to try fermentation and distillation .. so a couple years ago i did ... the result from one gallon of mash was about a liter of very strong alcohol ... note: don't try this at home and i was very careful to make sure there was no methanol 

A pot still is a type of still used in distilling spirits such as whisky or brandy. Heat is applied directly to the pot containing the wash (for whisky) or wine (for brandy). This is called a batch distillation (as opposed to a continuous distillation).

At standard atmospheric pressure, alcohol boils at 78 °C (172 °F), while water boils at 100 °C (212 °F). During distillation, the vapour contains more alcohol than the liquid. When the vapours are condensed, the resulting liquid contains a higher concentration of alcohol. In the pot still, the alcohol and water vapour combine with esters and flow from the still through the condensing coil. There they condense into the first distillation liquid, the so-called "low wines". The low wines have a strength of about 25-35% alcohol by volume, and flow into a second still. It is then distilled a second time to produce the colourless spirit, collected at about 70% alcohol by volume. Colour is added through maturation in an oak aging barrel, and develops over time. source: wikipedia

Basically, I made an improvised alembic. The tech is very simple and has been used around the world for thousands of years.
I do not recommend trying home distillation yourself. The process can be very dangerous. If you must try it, never leave this unattended.

My stove was electric. You are making alcohol - never, ever do this over or near an open flame. The risk of fire or  explosion is very high.

There are a huge number of instructional videos on youtube. Most show the same basic layout. I picked one of many for this post. It is probably not the best one so have a look for yourself..

Always remember to toss the first 10% (or so) of your production as it is toxic. Your own numbers may vary. Temperatures are very important, so find a good thermometer and use it.

The images with the enamel pot were taken about four years ago. The setup was used twice and has since gone to recycling. The enamel pot became a momo steamer.

One of the most useful tips I found with my setup was to use homemade bread dough to seal the pot. You can see it as the white ring around the lid. This helped make the process far more efficient by plugging leaks that depressurized the boiler. A pressure cooker may have been more effective, but the setup I used was much safer in that it eliminated the possibility of over pressurization or a clogged relief valve causing an explosion.

Circulating water to cool the vapor coil was an important step. I tried to use just ice but it melts far more quickly than I imagined. Adding the in/out for the cooling water made the whole setup work far better.

Be safe. Have fun.

nowhere : dance

 humanity in motion

NOWHERE explores the nature of the theatrical stage itself, a spatial mechanism continually transformed and redefined by the human presence to denote any place, and yet designed to be a non-place. The performers measure and mark out the space using their bodies, pitting themselves against its dimensions and technical capabilities in a site-specific performance that can be presented nowhere else.

Commissioned and Produced by the Greek National Theatre
Première: 14 October 2009, Ziller Building-Main Stage, Greek National Theatre

This central scene is dedicated to the memory of Pina Bausch.

musician wren: the song of the uirapuru

 bird dance, bird song 

The Musician Wren or Organ Wren (Cyphorhinus arada) is a species of wren named for its elaborate song. It is native to the Amazon Rainforest in South America, and west and southwestwards into the Amazonian Andes. In Portuguese it is known as Uirapuru or many other variants of this name, all based on the Tupi wirapu 'ru. Especially in Brazil, the Musician Wren is the subject of several legends and fables, most relating to its loud and beautiful song. One of these tells that when it starts singing all other birds stop their song to hear it. The Musician Wren is also believed to bring good luck, which leads some people to kill it in order to have it stuffed. Even though there are no reliable statistics of its numbers, the Musician Wren, due to its large range and being locally fairly common, is not considered threatened.

the song can be heard in the months of october to november when the bird builds its nest
