Hey all,
I've just done my first AG brew today (took hours!)...it seemed a little bitter straight out of the fermeter but hopefully I got the hop IBU reasonably right. I screwed up the boil volume and ended up 6 litres short which wasn't so flash but...1st time I expected some stuff ups.
But...while I was doing this I thought I'd do a quick and dirty kit brew to replenish the stocks.
It was pretty simple:
1.7 kg of Coopers Lager for the IBU
1.5 kg of Thomas Coopers Light liquid malt
300gm Crystal
50gm Black malt
50gm Choc malt
25 gms Cascade as finishing hops
S-04 yeast
21 litres
I just took a hydrometer reading after adding the 3.2 kg of malt and it came up as 1.010!?
I pulled out an old hydro and it read the same.
After using the HB brew calc it said I should get an OG of 1.055.
This is very odd. Has this happened to anyone else?
I thought the hydro was the real yard stick of how much in the way of fermentables you had and with such a simple brew it should've read MUCH MUCH higher.
Cheers,

Liquid Malt and Hydrometer reading
Re: Liquid Malt and Hydrometer reading
Sounds to me as though the extract had not dissolved and circulated through the wort properly before the sample was taken. Or your hydrometer is broken.
Don't worry about it - the beer will turn out fine.

Hey Tourist,
I made sure both malts were nice and hot (10 min in the sink filled with really hot water) and poured them into the fermenter with 4 litres of warm water from the specialty grains. It looked like it was desolved nicely though would it need a litre or two of boiling water to properly desolve?
I took a double take when the 1.010 reading came up but a second hyrdo showed the same reading.

Re: Liquid Malt and Hydrometer reading
I don't know exactly what went wrong here, but with all those fermentables, it is impossible to have a true reading as low as SG 1.010.
That is, unless you made your brew up to about 121 litres, rather than 21 litres (not likely, surely?)
I wouldn't worry about it. Let it ferment for about 2 weeks, and you'll have a nice beer.

Re: Liquid Malt and Hydrometer reading
So had you completely topped-up the fermenter to the full 21L before taking the reading? Or did you sample from the 4 or 5 litre volume? Maybe you were looking at an OG of 1.100, not 1.010.
Either way, something went tits-up with your reading, but as Warra said - it will all turn out for the best.
