I now have three demijohns full of cloudy apple juice, foam and sediment.
It might look manky but this is just after I'd stirred the campden tablets in, which stop bacteria growing. It will clear up a bit over the next 24 hours, actually they already look better now: these pics were taken at lunchtime.
I saved a few dozen apples for eating so what you see above is the rest of the two boxes full. Using the juicer was properly laborious. About 10 apples made maybe half a litre of apple juice. The juicing bit takes seconds, but it then produces loads of pulp, which needs emptying out of the machine before you can do the next lot. So half a litre ends up taking 10 minutes or so by the time you've fannied about emptying the apple pulp into a bowl and then periodically taking the bowl and emptying it into the compost etc etc.
Using an apple press would probably have been easier, but what the fuck am I going to do with an apple press for the other 51 weeks of the year? At least the juicer will get used for all manner of healthy natural juices or sit in the utility room cupboard with the potential to.
Next step will be putting the yeast in.
I actually used ChatGPT a lot for advice with all this and it was much more useful than trying to google and watching Youtube vids and that.
