After reading this thread for fun, I had to mix it up tonight! our 9 year old will be surprised when I tell him he has his own drink on tap! I'll keep it a secret until its ready to try.
I used a mix of sugars.
2 lb brown sugar
1 lb 13 oz white sugar (all I had in the house... Need to go shopping)
1/2 c honey
2 oz maltodextrin
4 oz lactose
Mixed with RO water to make 1 gallon. Warmed up until all sugar dissolved and it turned clear.
1 1/2 tsp citric acid (was a bit much, next time will try 1 tsp)
4 oz Penzey's single strength Vanilla extract
Enough RO water to bring volume to around 3 gal. I kept adding water until it was the perfect sweetness level for us, which is probably less that what would be expected. Threw in keezer on CO2 around 32 psi.
I plan on shaking and hope to have it carbed up in a few days.
It tasted really good, but hindsight is 20/20, and I think if it's well received & I make it again... I will go with 2-1 white sugar to brown sugar, and maybe 3/4 cup honey. With of course cutting down the citric acid to 1 tsp.
Color was a beautiful rich light gold. I'll post up a pic after its ready.
EDIT: after it chilled and carbed, it was still a little "off" from how I intended. I mixed up another 2 lbs of white sugar and 1 1/2 gal water and added that to the "brew". It foamed up pretty well as I was pouring the new sugar water in, so hopefully there is no negative side effect from that. That brought the volume up to almost 5 gal. I'll update with tasting notes after it finishes carbing.
