Quicker Ferment-why?

[zabond]

Put down a brew last week that was the same recipe as one I did in July
Coopers Real Ale
250g BE2
230 Med Crystal
280 Carapils
100 Carared
100 Carabohemien
100 Caramunich 2
300 DLME
Nottingham yeast @ 26* 20 ltrs ferm temp 17-19* og 1052
july batch sg @ 7days1026 fg 12days 1018
checked sg of this brew yesterday [5 days] already1020
only diff between brews was july brew Styrian plug added to fermentor this brew Styrian plug 25min boil
any thoughts?wouldn't think hop addition would speed up ferm time

Healthier yeast maybe? Air pressure was different? Water was different? Time of year is different?

Who knows... :unsure:

Could be lots of things as CB points out - but I reckon the most likely culprits are a fresher healthier yeast packet and perhaps you splashed or shook more this time and got more oxygen into the wort

As the rest have said, many factors will change the fermentation time.

Don't be too concered as long as it has dropped to you correct FG and tastes correct.

I'd go for the yeast theory. I used a recultured yeast (Ringwood) in a stout but I probably didn't use a big enough sample because it just blooped away in primary for nearly 3 weeks, whereas I would have expected it to be done and dusted in five or six days if I had used a fresh pack. Same principle with the kit yeasts.
