A number of things really and I wonder if those more in the know could help me answer them. Ive just brewed 100% satisfaction from M Ollossons book which called for 3300grms of malt extract with 75grms of Goldings followed by 15grms of goldings with 15 mins to go. Boil time 90 mins. Now I know that over the boil time I lost some liquid through evaporation but the target og was 1040 and I only achieved 1035.
Has anyone else brewed followig this recipe?
Also i strained the hop from the hot wort after cooling and through a fine sieve, however in the bottom of the fermenter there is about 1/2 an inch of what could be sludge or fines that have settled out.
Can anyone let me know what this is and how I can avoid this in the furtuer, that is if it is possible to avoid.
Cheers

First extract query/concern
If you boiled off an excessive amount your OG should be higher not lower than anticipated.
Did you correct your hydrometer reading for temperature? Is your hydro accurate? Mine is off two points.
If you used liquid extract did you rinse out the container good and get all the malty goodness into your wort?
If you topped off with water there is a chance you did not mix up the wort and water well and you may have a gotten a watery sample.
The sludge can't really be avoided it is break material, hop resin and such. That may also account for some of your lost gravity as you left sugars behind as well.

I would have thought that if I boiled off an excessive amount of water (I reckon that I lost 2 litres) I would also expect the og to be higher, but the batch length hasnt changed 23l so it cant be that.iowalad wrote:If you boiled off an excessive amount your OG should be higher not lower than anticipated.

The tins were well and truely washed out with minimal wort left behind.
Once it was topped off with water it was well mixed so I doubt that its that.
Im thinking that it could as you mentioned be the calibration of the hydrometer. I did check it in water at 20 deg c and it was spot on, however the wort was measured when it was at 28 deg c so Ill have to test it in 28 deg water.
Thanks for the suggestions

Thanks both for the comments about the sludge, ill not worry about that now. But i will test my hydro as that could be the problem.ColinKeb wrote:as iowalad says you may have not adjusted for the temperature for the wort. that goo in the bootom is meant to be there dont worry about it. as you used extract it cant be down to poor sparging , so it really must be down to the temp of the wort.
Thanks
