I started a batch of that same wine last August 25, following the ingredients except with 3.5 lb peaches instead of the 3 lb called for. Also, after preparing the banana liquid according to the recipe, I followed my usual method instead of doing the incremental sugar thing - everything into the bucket one evening except the pectic and yeast, then next day add pectic in the morning and pitch yeast in the evening.
But to get to the point, starting SG was about 1.094 so it should end up at around 12%. It's taking its time clearing - after six months and three rackings it's still hazy. At the last racking it tasted promising, with body from the bananas and no banana flavour remaining.
