carbonating period

[chuffer]

For my last brew I tried to follow the 2 + 2+ 2 advice that tends to be circulated on this forum. However, the lady at our LHBS was surprised to hear that I'd kept my bottles/barrel in the warm for 2 weeks and suggested that 4-5 days is the norm, followed by a longer period in the cold - she suggested that this would lead to a clearer pint. Is she wrong? Is 4-5 days enough time to carbonate?

That's interesting...
To be honest, on the odd occasion I have pop a bottle after a few days it has been well carbed.
I think I'll test this on my next brew.

I don't think there is a one size fits all..

Different styles, different carb rates, different yeast some flocculate more rapidily during fermentation which can affect the priming rate. Also different temps.. and time between primary fermentation and the time it was bottled

There are too many variables to give a universal time but 4-5 days in my expereince is not enough.. Even two weeks sometimes a better carb comes in a few weeks after than even when stored colder

Actually, on a related note; when we say two weeks in "the warm", how warm is warm and how how warm would be too warm?

So many W's.!!

Room temp, 20 degrees.....the brew in question was an APA

My first dark beer took longer than a week, was ok after 2, better after 3.
Cider was very quick - about 3 - 4 days in the warm.

Maybe it depends how long you can stay from drinking it? :)

You have to remember that during bottle carbonation if the temp is too warm you can still create diacetyl and off flavours from the bit yeast thats in there so I generally carbonate for 4-5 days at about 20°C after which I then take the temp down to 2°C. The beer is clear in 2-3 days but obviously will improve with longer conditioning . This shorter cold conditioning may be better for beers that are hoppy and you can catch them young.

Almost without exception most of my beers are finished and drinkable within 3 weeks of starting, however they are mainly pale ales. I would probably extend teh warm and cold conditioning for dark beers and porters.

Might be wrong but Surely crashing too early after priming will leave diacetyl in?? Its present in almost all ales but the yeast will clean it up when left in the warmer temps for longer..

It is why people should never cold crash until a good few days maybe a week after fermentation is complete

With the small amount of yeast in the bottle the diacetyl will be low but may still be present. Even after main fermentation 24- 36 hours is enough to mop this up at 13- 14 °C. So once I have carbed for 2-3 days I will put the temp down to 13 but only over night and then cold crash. The time it takes to fall down to 2°C is enough to get rid of the diacetyl and so far I have had no problem with this in any beers with this regime.

Sorry I mis understood, I thought you meant that by carbing temp it will create the diactyl and the need to crash after it.. which is why I would think it would have needed longer.

Everyone's setup is different and people find what works for them..

I would still worry as the fermentation is still taking place however small it still wouldn't finish and clean up.. but tbh the chances of producing much from the priming is pretty low anyway.

It is strange, I found my witbier carbed up okay pretty much after 6 days, although another 7 in the warm it will change a lot.. some can take nearly a month to get a good carbonation in even if sat in the cool.. I guess they are done when they are done :-? higher flocculant yeasts can take longer to carb up

sorry to hijack but what temperature do you guys tend to aim for for the priming/conditioning periods?

Also, given the recent nice weather, and in the absence of a empty brew fridge, where do you tend to keep your bottles when they're in their 'cold' phase of conditioning?

Cheers

I've a cupboard in the garage that I can get down to around 10 during the day if I put a couple of ice pack in there.

In my original post I did say it may create a bit of diacetyl but more so if the temp is not controlled say allowing the temp to go to 25°C or above a for a few days. This is why I keep my secondary lowish at 19- 20 and so little chance of diacetyl. You are right in that if it is created by too warm temp then would need a few days to munch it up again.

Immediately after priming I keep mine at 20 oC for a few days (the last one was 2 wks but I'm tyring to figure out if it's better to reduce this time slightly)....after carbing beer goes in the garage which was prob somewhere around 12oC until v recently.

Interesting thread. I have had problems with my last couple of brews carbing and I am not sure why. This time I have used more sugar (around 200g) and the bottles have been in the warm at around 20 degs for 10 days now. I have never cold crashed however. Will give this a go. How long do you leave the beer at 2 degs for before you bring the temp back up to drinking temp?

Brewing a citra hopped extract beer if this makes a difference.

Thanks

200grams is very carbonated.. I am surprised that doesn't gush out. After bottles have been in the warm you could try putting a few in the fridge to crash.. it may help the head retention to tighten up a bit. obviously remove the bottles to server at desired temp.

if you are having problems with things like head rention don't just throw more sugar at it, you will cause more problems in the end.

For me I leave it at 2°C for a few days until it is clear and then you can either leave it there or transfer to somewhere about 10-12°C for storage before dispensing. Cooling as low as possible helps to precipitate the proteins that cause chill haze and once they are out you can store at any temp above that without the haze returning.
So in short, once it cleared it's ready to go, for some the haze does not matter too much but if you can get it clear then why not!

I fill at least one PET bottle per brew to monitor carbonation, some like my wheat beer carbed up in just a few days, most are ok after a week to ten days but on a guinness clone that I split into two batches with different yeasts, one carbed up in about 10 days the other took 4 weeks, without the PET bottle testers I would have been trying flat beer for the first few weeks.

I really need to do the PET bottle thing......

Before I had my brew fridge, I had to go two weeks as I think temp in my room was under 20. Now I have the fridge with stc and heater, one week at 20c is all that is needed. One PET bottle to use for squeeze test. If you don't have PET just use an empty coke bottle. Keep out of light and it's fine.
