Elderflower champagne priming sugar

[Mevdog]

Hey guys,
I've started making an elderflower champagne for the first time and now it's bottling time. The gravity has dropped to 990 and it's pretty dry. I was hoping to prime 2l plastic bottles with sugar and possibly back sweeten some bottles to experiment with. First question, is it ok to bottle in 2l plastic bottles? If so how much sugar would you recommend for priming? It seems to vary from 5-10g per 500ml, so in my case 20-40g per 2l bottles. Pretty big variation and don't want a flat drink nor an explosive... final question, what and how much would you add to 2l to sweeten it up? I've got xylitol and can get some canderel etc if that's good.
Thanks in advance!

Unless you've got loads of company or are in the habit of drinking it by the pint I think you might be disappointed with 2L bottles. The two issues I can think of are pouring it without disturbing the sediment will be hard work [a bit of sediment in your beer is one thing, but it doesn't look nice in a wine glass], and unless you drink it quickly it'll go flat before the bottle's empty.
