Everything I had read on various forums had you boiling the ingredients, then adding more water to fill the fermentation jug. But when I went to help my son in law the instructions with the Cooper's kit had you warm up the can of syrup in hot water, and boil 2 liters of water in a seperate pot. You then added the two ingredients ( can of syrup and bag of stuff) into the fermentation jug, poured the boiling water over the top, and then stirred well. After that you added the rest of the water needed to fill the jug, and then poured the yeast on top of everything. This just seemed odd to me because I'd never read anything like that on any of the forums I'd gone to.
By the way it's been almost 2 weeks and it does taste like flat beer, so we must have done things right. We'll bottle it this weekend and let it sit another 2 weeks before chilling.
The Coopers kit comes with a bag of what looks like white lemon drops that you add to the bottle when filling to help it carbonate. I'm guessing these sugar cubes are just the right size for the bottles they provide. But if we use some smaller bottles we'll have to measure out and add some sugar instead.
