Reddit mentions of Coopers DIY Home Brewing Carbonation Drops

Trying to stir in the priming solution into your fermenter is just going to stir up the yeast and likely introduce oxygen.

Honestly, you need to buy something. Either buy a bucket to rack the beer into (which will mix in the solution solution), or buy carbonation drops.

Well if you live in Canada like I do, get the President's Choice Fresh Pressed Apple Cider from Loblaw's/Superstore. It's $5 for 3L and works awesome as a base for all my ciders. I almost always use Lalvin BM 4X4 yeast, which ferments nice and dry at basement temps, good body, retains a lot of fruit characteristics. Most of the time I use plain ol' white sugar to bring up the SG. The PC cider on it's own will get you to around 4-5% ABV, but I like to bring my ciders in around the 8-10% range. If you want to split the difference and go for, say, a nice 7% ABV you're looking for between 1.050 and 1.055 SG. Ferment it out for a few weeks until you see little to no more activity in the airlock. Rack to secondary and add any additional flavours you want. From there it's just a waiting game depending on how long you want to age before bottling, the clarity you're looking for, etc. For bottling I use either 750ml flip tops or 650ml beer bombers. I use two of these tabs in each bottle for conditioning. If I'm worried that there's not enough residual yeast left at bottling time, I put a few grains of dry BM 4X4 per bottle before filling. I go at least 2 months before cracking open the first one.

Can pick up some of these , drop one in and recap. They are normally a waste of money, but I think they are the best solution to save beer that has already been bottled.

I use these for my cider and haven't run into problems in the two years I've done it.
