Brewing Course - Class III. 28/9/2010

Theoretical introduction in to the cultured drinks:

origin of major cultured drinks, advantages and disadvantages of cultured drinks, procaryotes and eukaryotes (similarities, differences), growing cycle, growing curve, aerobic and anaerobic fermentation, kombucha in detail: SCOBY, growing media, standard culture period, metabolism byproducts

Tasting of kombucha batches brewed two weeks and week ago:

KT-I (22/9/2010) - taste 6/10, sweetness 5/10

KT-V (22/9/2010) - taste 7/10, sweetness 6/10

KT-VI (22/9/2010) - taste 6/10, sweetness 6/10

Goals of this class:

- summarization of the recipe in to the scientific, international format

- tasting and subsequent production of the new batches of favorite kombucha drink

- experimenting with new flavors, secondary fermentation

- preparation of the drink for the next class - honey cooler

Basic recepy for the class:

standard recipe developed on 15/9/2010:

Vc (culture volume)= 10 l; sugar amount = 0.8 l; tea amount = 57 g; starter volume = 0.5 l

Transfered in to the international standard:

sugar amount = 6.24%(w/v); tea amount = 0.57%(w/v); starter volume = 5%(w/v)

Cultures to be brewed during the class:

KT-I Gunpowder tea (1), Vc=18.9 l; wt (tea)=107.73 g; ws (sugar)=1179.36 g; Vs (starter volume)=945 ml

KT-II. Lapsang souchong (2), Vc=11 l; wt=62.7 g; ws=686 g; Vs=550 ml

KT-III. Pu-erh (3), Vc=8.5 l; wt=48.5 g; ws=530 g; Vs=425 ml

KT-IV. yerba mate (4), Vc=3.78 l; wt=21.55 g; ws=235.87 g; Vs=150 ml ===> Vc=3.3 l, solution more concentrated than the recipe asks for!
