Did you take a Final Gravity reading ? If yes, what was it ? (ie: VSOF being no longer visible does not mean that the beer is ready...)
Brew lives in the FV for two weeks and the fermenting is well and truly over. I can't remember the numbers but both about 1005-7 and started above or near 1050.
What was your fermentation temp? (Too low can lean to sluggish fermentation or stuck fermentation, meaning there is still unfermented sugar in the beer)
Were there any changes in temp ? (Yeast do not like swings in temp. If it drops quickly by only a few degrees you can shock the yeast)
Dunno, I know the start temp (about 22-26c) was good and then the temp slowly drops over the week to about 18c. Come second week it did get a wee bit nippy (16c) as I do not have heater or anyway to control heat. This system has worked fine for about 15 brews.
How clean are your bottles? (do you do separate cleaning / sanitisation soaks?)
10 Empty bottle into a glass, rinse dregs out, squirt in some starsan, store, drink content in before mentioned glass
20 GOTO 10 if not have had enough
30 WHILE 10 (always drink while brewing) take out of storage dunk into a pot of VWP, rinse in clean water, squirt starsan, fill with new beer
40 GOTO 10
When is the last time you replaced all of your hoses / filling equipment that touches beer ?
Just got a new valve from Coopers when I wore out the old one. Rest still the same.
The fun part is the brew afterwards other than being a bit tame in taste (20g Cascade didn't have enough oomph in the flavour department as I had hoped, but hey it was a leftover brew) they are behaving well.
