[foodhackingbase] dark beer experiment - first try

[Frantisek Algoldor Apfelbeck]

Hi to all,
I'm finally ready to make my first batch of beer aiming for dark beer.
I've updated the recipe and partly procedure which I want to fallow, you
can find both on our fhb wiki

https://foodhackingbase.org/wiki/Recipe:Dark_beer

The aim is to make beer similar to Velkopopovicky Cerny Kozel
http://www.beeradvocate.com/beer/profile/448/16273/ which is 10 degree
plato, 3.8 ABV, caramel and chocolat flavour. It is nice beer to drink
not too strong, good for the summer when working. The one which I am
doing now will be definitely bit stronger of around 6 ABV not sure about
the other diferences.

I should mention that I can controll the temperature within 2C
difference by having the brewing vessel (14 l of brew in stainless
steel) in a water bath heated by aquarium heater aiming at 18C or so. So
far Salfbrew T-58 is the yeast of choice and for the hop Kent Golding
with (4-5% aa). For the malts if counted per 10 l batch (however I do 14
l) it fallows:

25% (w/v; 2500 g) of Pilsner malt
5% (w/v; 500 g) of Munich malt
1.5% (w/v; 150 g) of caramunich 3
1.5% (w/v; 150 g) carafa2 (steep separate?)
0.5% (w/v; 50 g) cara aroma

I'm still not sure if 40 min aeration with the stone at the end is fine
and if adding the carafa2 to other malts will work for mashing or if it
should be steeped separately. The water should not be of any extreme
type here, so hoping that would be fine. I will have to use a straining
bag for the malts and maybe hops and I plan to apply phosphoric acid for
sanitation. The stainless steel vessel is pot with wide top (as wide as
bottom) with two entrances. I would like to fill it up with brew as high
as possible and close it with water/air lock (entrance number one) and
mechanical thermometer probe (entrance number two). The vessel is easy
to seal air tight, it has silicon ring under the lid. The worth cooling
should be done by cupper chiller which I still have to make, hoping I
have the right tubing to connect it ...

That would be all, I appreciate any comments, tomorrow should be the day
of preparation, I'm just about to leave to grind my malts for first two
batches, second being done in a week time I hope it will not oxidize in
the meanwhile too much. I will upload more photos etc. later on.

Sincerely from Jeju,

Frantisek
