The aim of this project page is to colect all events and small projects related to Food hacking theme made by brmlab people or made as an events in brmlab hackerspace.


Even some of us had already knew kombucha drinks, first kombucha homebrewing evangelist was Frantisek Apfelbeck (our member for some time and also founder of Tastebridge group in San Francisco hackerspace)

Few Food Hacking events were organized all related to fermentation techniques. Kefir grain and honey based fermented drinks were also made.

You can ask some brmlab members (ruza, ata) for kombucha SCOBY (mother) to make your own.

Stevko is brewing his own Kvass.


Beer brewing workshop is planned.


mix czech (domestic :)) rum with Club Mate


Stevko is making mead in the kitchen in the bottom shelf. Do not stir, do not shake, do not touch. Fermentation started: 2012-08-31. Expected duration of the first phase: 6 weeks.

Used honey: JSG blossom honey

The mead looks good enough after four and half weeks and will be drank at meetup (on 2012-10-02).

Variations to try next:

  • shorter fermentation (sweeter)
  • add sugar for sweeter taste while producing more alcohol (during longer fermentation)
  • two phase fermentation
  • different kinds of honey
  • maybe some temperature variations
  • when boiling water add few bags of tea or herbs before adding honey (try differend kinds of tea for different tastes and colours)


  • 1 box of yeasts
  • 3 kg honey
  • 8 l water

We did another batch that was more sour (some hackers preferred this taste) and generally well received. The reason for sourness is unknown, probably less sweet honey, since we left it fermenting for approximately same time.

The third batch was supposed to be made from pasky's home honey with cinnamon, however too much cinnamon probably killed yeast and mold started growing inside the jar, so that batch was flushed.

Czestmyr is planning to do some more mead with other types of yeast.


On 2013-03-13 some cabbage has been put into crock to ferment and to become sauerkraut. Later, bacteria that ferment it (lacobacilus and other) might be used in biolab. Resulting sauerkraut will be either eaten in one large sauerkraut session or might be stocked in brmbar.
