I just got a Tap-A-Draft system (http://www.northernbrewer.com/shop/tap-a-draft-system.html) because I do not have the room for a full kegging system.
The TAD came with 3 6L PET bottles. I have 2 5 gallon batches that are ready to be bottled and I have a 3rd batch I am about to brew, so I wanted to fill 1 6L (1.5g) bottle from each batch and 12oz bottle the rest. My problem is that I can't seem to find a real source that tells me how much priming sugar to use per 1.5g bottle.
I've seen everything from '6 slightly rounded teaspoons per bottle' to '1 heaping tablespoon' to '1/3 cup per 5 gallons'.
EDIT: These 'measurements' do not make me feel good, I usually like to do my sugar by weight.
I would like to know if anybody has any experience with this.
Also, since I am only going to be putting 1.5g out of my 5g into this Tap-a-Draft bottle I normally bottle a 5g batch with 5 oz. of priming sugar. It looks like the TAD takes much less than that to carbonate (I'm assuming because you use CO2 for the dispenser) so I will need to factor that in, if I use 5 oz. for 5g I should only be using 3.5 oz. to bottle the remaining 3.5g in my 12oz bottles.
Here are the instructions from Midwest Supplies. They say to add 6 rounded teaspoons to each bottle directly. Do you not need to boil the priming sugar w/ water first? I usually do that when bottling so that I know it is disolved, then I put that in the bottling bucket and rack my beer out of the carboy onto that to make sure it is mixed well.
Will I be ok if I bottle the TAD with the same ratio of priming sugar that I use for the regular glass bottles or should I be using less priming sugar in these PET bottles meaning I would have to do 2 different mixtures?
