Hi all I would really appreciate your help with this one please.

Details are as follows:-

1X Brewferm Velvet Irish Stout Liquid Malt Extract Kit
1kg Dextrose (had been sealed unopened, in a bag but has been in the shed for a few weeks! hmmm)
.75kg Dextrose (brand new from hb stored unopened)
50g cocoa (from a fresh tin)
50g instant coffee from a tin that had been opened previoulsy and sat in the cupboard.

Method:-
1) Sanitized everything using VWP.
2) Boiled 4 pints of water.
3) Gradually added the 1.75 kg of dextrose to the boiling water and stirred while adding to avoid burning on bottom of pan.
4) Added the cocoa and coffee to the boiling sugar solution and stirred carefully while adding. Left to boil for approx 15 minutes.
5) Added the malt extract from the can into my FV.
6) Added the boiled pan of stuff from step 4 through a sieve.
7) Stirred vigorously.
8) Pitched the yeast.
9) Sealed lid, added air lock and tested for air tight which it was.

OG on 03/10/2011 :- 1.044
SG on 06/10/2011 :- 1.010
Number of successful brews done previously :- 20
Temperature :- steady 22-24C

So it started fermenting vigorously and quickly (within 3 hours I would say). Loads of Krausen on the top for the first 24 hours or so.

Stank the whole room out but not a bad horrid smell, just the normal smell of fermentation but a lot of gas being given off, lots of

bubbles in the air lock. I checked today (6th Oct) and noticed the bubbles had slowed down significantly so decided to take a peak to

see what was going on. Discovered a significant number of white blobs floating on top (please see pics). I sanitised a spoon and scooped

some out and tasted and smelt it. No real bad smells or tastes to report so I guess that's a good sign? Just some really odd lumps

floating around on the top (see it on my finger in the photo). There was also what looked like an oily/shiny silt on top. My main

concerns is the speed of the ferm and the blobs?
 
It looks like it has finished fermenting and is in the process of cleaning up after itself. The important thing is that it doesn't taste off - if you had acetobacter infection or other you would know about it as it would be rapidly becoming vinegar.
 
A lot of bacterial infection produce a white film over the surface of the beer and will taste and smell off. If it tastes ok then it's probably ok. I would let it sit at fermentation temp 18-21c for 3-4 days then put it somewhere cooler (garage ) and let it settle then bottle or keg. :thumb: :thumb:
