Bottles Won't Carbonate

Post by ADDLED » Sat Nov 29, 2008 10:39 pm

hi, ive bottled a strong ale and added a teaspoon of unrefined sugar to each bottle but a week later theres no fizz. i tried repriming with another teaspoon and the bottles frothed up so i know theres yeast activity, but theyre still flat a week later.
Any ideas?

Yeast doesn't work that quickly, that's CO2 coming out of suspension - adding anything granular will give it something to form on.

I know these suugestions all sound a bit obvious, but are the bottles somewhere warm enough? Or was the beer really bright when bottled... I find it can take a week for the secondary fermentation to even get started when the beer is very bright.

Tks Sparky,
1) they're indoors approx 20degC.
2) the beer had been in the fv for 3 weeks and was v.v.v. cold when bottled, then brought indoors to secondary ferment in the warm. When i bottled it was clearish but not bright/clear, and still isnt bright in bottle a few days later. In fact its quite hazy, but not chill haze.
Tastes bloody nice tho.... :roll:

Perhaps it just needs a bit more time. I tend to do the secondary fermentation around 20-25°C, and also make sure the temperature doesn't drop overnight.

At least it tastes good! :beer:

Some of mine have been quite flat after a week in bottle. After a month they're fine, though they tend to improve as beers if left for longer.

Patience. Even weak beers under 4% ABV need 4 weeks to develop. Strong beers for winter sipping need a couple of months.

I would tend to leave beer in the FV for no longer than 14 days regardless of the gravity. It will then be bottled still at room temp; you still want the same temp for priming and bottle carbonartion (the warm week)

If they've been out in the cold for a small quantity of time (less than a week) then I'd wait for the yeast to liven up. Take it each day as it comes, if its flat then open a bottle every 2 days days to check carbonation.

If the yeast is totally dead then make a fresh yeast starter (500 mls, 4 teaspoons of spraymalt/glucose and a sachet of yeast, ferment for 2 days) then pippette 2.5mls into each bottle)

I make a few Barley Wines that sit in demi-johns for 4 months +; the yeast is always inactive enough for me to employ the above technique for bottling.

Thanks for the advice everyone. I'll try one or two next weekend.

I always find that mine take between 2 and 3 weeks to be properly carbonated, once bottled mine are stored at around 15C, thats just because thats the temp of the place where i store my bottles.
