i've just finihsed bottling mine and used empty 2l coke/irn bru bottles.  i reckon if i open the lid every day to let out the extra gas, then we should be fine (hopefully anyway).  it's a gorgeous pink colour and really looking forward to tasting it properly in acouple of weeks.
oh and, no, i didnt sterilise the bottles dizzypig, cos i reckon we'll have them finished long before they go off!
