Bio-Culture exchange

EN - During the evening/night hours of 14th and 15th of August 2013, we will be sharring variety of probiotic and other cultures in Brmlab. We will also start some cultures, share some cool recipes and much more. So if you like to pop in, please do so, bring some snack and have fun! The event is donation based no one turned away for luck of funds, we should cover what we spend. The excess could be used on feeding some cultures like kombucha so it could be available in Brmlab (but doesn't have to be grown there). Below is the list of cultures and people sharing them which we know of already.

CZ - Během 14 a 15 srpna 2013 bude v Brmlabu uspořádané sdílení probiotických a jiných kultur. Chceme také rozjet pár várek něčeho zajímavého a věřím, že nás čekají různé další experimenty. Takže chcete-li se přidat výborně! Rozhodně doporučujeme přinést nějakou tu pochutinu, vlastní výtvor se obzváště cenní. Akce je založena na klasickém přístupu kdo chce ať se přidá, dary jsou vítány, ale nevyžadovány. Měly by se uhradit náklady na akci, přebytek by mohl být například využit pro nakoupení cukru atd. na krmení kombuchové kultury, která by mohla být pro zájemce přístupná v Brmlabu (ale zda jí tam přímo pěstovat je otázkou). Níže je uveden seznam kultur, které budou k dispozici na rozebrání a experimenty.

List of bio-cultures to share/Seznam bio-kultur pro výměnu

kefir culture (+-50 g=10-12 grains/zrn) FAA

water kefir culture (+-100 g = many decent size grains/mnoho pěkných velkých zrn) FAA

kombucha, in this case/v tomto případě Kombucha cosmopolita culture (+-400 g) FAA

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.

DNA analysis driven food

For the people whose genome passed out DNA analysis and their SNP (Single-nucleotide_polymorphism) are known (ie using services) personalised dinner was presented at Denisa Kera: jsi co jíš, ale můžeš také jíst, co jsi event.

Predkrm: dle genealogickeho profilu - DNA kulinarska exkurze v case & prostoru
Hlavni jidlo: ADRA2A, MTHFR & TAS2R38 variace

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.

The second version was started on 2015-04-26. We used seven cabbages.
