I have tried this recipe three times, each a different version. My first was the recipe as written, the second was with cinnamon sticks, and the third was with the addition of some ginger crystals. I had to scale the batches down to fit a 5 gallon carboy. For this amount, I use 4 gallons of Mott's (I can't find tree top around here, I am in Columbus Ohio), 8 lbs of sugar (Kroger Value), and the Lalvin yeast packet.
If you want to add cinnamon, I found that 6 sticks was perfect for this batch size. Make sure to add them about 4 days in. This will allow the ambient alcohol content to rise high enough so that you don't have to "sanitize" the sticks themselves.
I am bottling the ginger recipe tonight, it is pretty delicious. I added "Prince of Peace Honey Crystals", (4 packets). I will of course give an update once I have time to try it.
