When I first started making cider from fruit in my first attempts I made single fruit varieties some sulphited some not. Any excess juice was just bunged in all together. I learnt that the mixed juice was far nicer as an end product.
The next year I started to weigh out my apples and try to make a consistent blend of them, in an attempt to produce a reproducible end product, and have had about 8 years of success, but I used Campden tablets at a rate of 1 per 5 litres of juice. The remaining apples were just bunged in together and fermented unsulphited, and it was always this batch that was hit and miss.
I’ve now got 9 trees on a my plot, that should start and bear fruit in a couple of years.
There are 2 National Trust for Scotland Estates near where I live. Both have an orchard and walled garden with known apple varieties. I’ve asked both for some scion to graft on to rootstock next spring with a view to expanding my collection.
A previous neighbour of mine told me to label the scion, and then put it in the salad draw of your fridge for the winter, and then graft it on to rootstock in March, using the correct grafting tool.
So going back to the new fruit source from the farm my neighbour took on. As I mentioned, in my previous post, when ever I get a new source of fruit, and when it is in small quantities I ferment it as a single juice, to see how it tastes, unsulphited. It’s this that has turned to vinegar.
I’ve always had the similar problems with pears.
I’ve known pears to taste absolutely fantastic when initially fermented and up to 6 months after carbonation in a bottle, but another 6 months on the remaining bottles were foul.
So to be clear, the vinegar production was not intentional.
I aren’t dependent upon my cider production for a living, it’s just a hobby that got out of hand.
