Just about to bottle this, I forgot to top-up the apple juice at any point so it might be a bit strong... just a few questions, can I use apple juice as a primer in the bottles instead of sugar? If I use say, 40-50ml in each pint bottle (or work it out for the 4 litres and batch prime, while adding the vanilla extract) would that be enough to carbonate and sweeten without expolding the bottles? Or is it better to use sugar? and might brown or demerara sugar give a nicer flavour? Hmmm, maybe I should experiment!
