Fermentation too quick?

Post by rowdy75 »

G'day all,

I have just put down my first brew, so I have a bit of a newbie question.

My brew (coopers kit lager with ale yeasts & dextrose) fermented at around 26Deg C for four days before I got the same reading twice (morning / afternoon) on the fourth day at 1010,which is the suggested reading before bottling. So I bottled the brew (PET bottles) and have left it for 8 days now (no exploding bottles). I opened a bottle two days ago just to see how it was going and it has the right colour, carbonation, great head and tastes ok....maybe a bit too sweet but still very drinkable.

I have seen many posts recommending between 8 - 14days to ferment......have I jumped the gun too early here by allowing only 4 days? What is the quickest someone has fremented and what were the results?

Appreciate your help!

What were the "ale yeasts"?

Same reading twice usually means wait at least 24 hours between taking the readings, though at 26C most ale yasts should have finished up within a 4 day period. Never bottle by reading, always make sure you have a reading that is stable! Just because you have hit the finished gravity they suggested does not always mean the brew is finished.

I once fully fermented a bacth of Witbier in less than 3 days, kegged and drinking the following day!

Give the bottle another few weeks, they should improve considerably!
Prost and happy brewing!

Cheers Kev, a mate had suggested that the coopers lager cans come with Ale yeasts and temps between 22 - 28 would be ok, not sure on the yeast specifics.

I'll keep that in mind next time, I will wait longer to ensure stable gravity over 24 hrs....I was just too keen to get it in the bottle and start drinking!

Appreciate the tips.

Ok, you used the kit yeast then. Most likely it had finished fermenting at those high temps. I would suggest being down around 16-18 for a lager (and most beers if you can).
Prost and happy brewing!

Yep the Coopers yeast is voracious and would have finished in that time. So you did everything fine, and in a few weeks the sweetness will have attenuated somewhat, and you should have a decent, drinkable beer.

Now check out Simple things that make HB better for your next brewing steps! :)

G'Day,
I ferment my brew outside, in Dec Jan the temp was well over 40 C Degrees, My brews took one day to ferment, the beer was good .
I gave up bottling , to much hassles and bought a keg system.
I haven't blown up a keg yet,
Another bloke here ferments his beer in a 3m X 3m garden shed and he makes a good brew.

Cheers,
Bob.

Good on ya Bob! Welcome to the fourm!

I made heaps of "good" brews in QLD summer heat with kit yeast. But now that I have fermented temperature controlled liquid yeast driven all grain wort, it is VERY hard to go back! ;)
Prost and happy brewing!

It is bassically that, an all grain wort ( beer made from scratch= all grain) using a liquid yeast to ferment and some sort of temperature controlled enviroment like a brew fridge with a fridgemate. :wink:

Update to the thread......beer turned out much better than expected for my first batch. Me and a couple of mates had a big session on it recently, they were also big fans of it.......I'll be putting down a new one this weekend :D
