New to home brewing and made a coopers IPA. It’s been exactly 2 weeks of bottle conditioning with the recommended amount of coopers tablets.
I tried one today and I liked it a lot. My question is this - will longer in the bottle (in addition to this 2 weeks) create more carbonation ? I would love to have some more carbonation in the beer. Thanks for the info/ advice.
Once all the glucose of the tablet is consumed, no further carbonation will occur. After two weeks, whatever carbonation level you have now is what it’s going to stay at.
The exception is if wild microbes got in the beer during bottling. These bugs consume carbohydrates (slowly) that brewers yeast cannot and continue making CO2. This is something you do not want because it can create bottle bombs. Once you have determined that carbonation is complete from the tablet, refrigerating the bottles is good insurance against continued carbonation by wild bugs.
Sometimes carbonation will continue in the bottles for 3-4 weeks or even a little longer, especially if the beer was dry hopped like in the case of most IPAs. Hops contain enzymes that slowly produce more fermentable sugars that the yeast will eat in the bottles – this effect is known as “hop creep”. Otherwise typically your priming sugar (Cooper’s tablets) will be all eaten up in the first few weeks and then stabilize. If you want even more carbonation next time, you can add an extra 1/2 tablet or about 1/8 to 1/4 teaspoon sugar per bottle. Or, if you bulk prime (pre-dissolving all the priming sugar together to add in the bottling bucket), you can just increase the amount of priming sugar by like 10-15% or whatever to get just a little extra fizz next time.
I have found that sometimes it takes up to 3 weeks for my beers to fully carbonate in bottles. It’s going to depend on the temperature they’re stored at, health of remaining yeast, and other unpredictable factors.
In my experience, temperature plays a big role. Typically 70-72F (21-22C) for 2 weeks is needed for 4-5% ABV beers (Longer for high gravity). Also, I’ve found it takes 4-6 weeks to condition to peak flavor. I’ve never had good luck with the carb drops, I batch prime using the Brewer’s Friend calculator.
