biab , og question,

[artyb]

i have been pitching the yeast in to my 1st biab brew today, an ipa style

it was brewed 3 weeks ago and kept in a cube ,
i popped in the hydrometer in, and it read around 1.030

is this a bit low, :wha:

i used
4gk of marris
1/2 pale malt
1/2 kg of crystal,

mashed for 100 mins,
and with a dunk sparge in an fv with hot water,
a 75 min boil

i did end up with 6 gallons of wort ,

EDIT ....i have just realized the wort came out at 7 gallons which may account for the figures

Brewed 3 weeks ago, pitched yeast today? What's a cube?

Anyway, that aside, 1030 does sound low, especially given the amount of fermentables you listed. What temp was it at when you measured 1030, i.e. did you correct for temp?

 

[artyb]

its an aussie and american method,

heres my cube of wort,

its a no chill method of wort chilling and storage ,
they can be stored for months before fermenting, some have been kept for 2 yrs,
the temp was cool when i measured it today ,

it does seem low, what was your mash like? temp, water to grain ratio etc.

 

[JohnRB]

and it read around 1.030

is this a bit low, ,

Beer Engine suggests your OG should have been around 1040. So yes, it does seem a bit low.

Every day is a school day.

here's a post i was reading earlier today with regards improving efficiency. viewtopic.php?f=21&t=32825
might be worth checking the water to grain ratio as this is the only thing that i can think of :wha: . It should be around 2.5:1

one guilty party has been found..

the placcy hydro from boots reads 990 in plain water where as a couple of glass ones read 1000

so im 10 points up... :party:


EDIT ... i have since realized that the total wort came out at around 7 gallons ....

 

[artyb]

i did ferment a demijohn of the dregs from the boiler hot break and all...
over the last 3 weeks..and bottled it yesterday on tasting it was very nice although not very hoppy,

heres the before fermenting,

and 3 weeks later ... :)

ive put 4 litres into pet bottles .. will sample at xmas

and a couple of glass for long term keeping

really enjoyed the biab experiance ...produced some nice beer ,

 

[artyb]

i have now put nearly 6 gallons into my new ,fermenting cabinet in the kitchen,
its heated by a 60w lamp on a temp controller,and all insulated ,

i also have a slab of polystyrene one top of the fv..

lid and door open

the dearest part was the door[to match the rest of the kitchen ]...£20

and the controller £12,

the woodwork came from the neighbours kitchen renovation,
as he bought a huge ex display kitchen and scrapped a fair bit... :party:

the cabinet is on castors, which ive been saving for years for something... :nah:

should be good enough for some all year brewing at good temps.. :thumb:

 

[jonnymorris]

What's the cylinder with the lights, front left?

 

[LeedsBrewer]

its a 60w lightbulb in a metal can. The stc1000 will turn it on and it will heat the cabinet up to desried temp.

artyb - that build is looking very good! :thumb:

 

[PD]

nicely done cabinet.....

 

[artyb]

What's the cylinder with the lights, front left?

yup its a tin can..

with a lamp holder fitted, 6ow bulb is the heat source :thumb:
