Having tasted this, it's already quite alcoholic and so I've added 2kg of bananas before I feed, I think it does need this to blend alot of parsnip and sultanas and will add fresh flavour before racking, it fizzed happily as I put it in so very much alive. I will make a syrup from half white half demarara when it's had a bit of time on the fresh fruit, I don't want to leave it too long to oxygen its bang on 20 ltre mark but it must be a gallon of fruit.
