Sorry not noticed this one before.
Knifes: apples are acidic and they react with iron, so use stainless steel or aluminium at a push, though don't store the juice for a period of time in aluminium or you could end up with altzima's!
Right a few tips. Firstly one persons cider is another's "wine", and "real" cider is something completly different.(nothing but pressed apple juice, not even yeast)
It is as hard and as easy as you want to make it.
Proper pressed juice cider, depending on your equipment can take a long time. It took two of us a whole weekend to make 40 pints. You have to factor in a rough ratio of only (at best) 50% juice conversion. So if you want to fill a home brew fermentor (40pts) your going to need around 100Kg of apples! Thats a lot of chopping /scratching/pressing.
Also search for cider, stonehead a few years ago did a good piece.
Here's a bit of my advice from last year I've copied and pasted:
1. Try to get a mix of apples if you can't get real cider apples. (Kingston Black being the most famous)You need a balance of bitter (tannin), sweet and sour (acidity) a "vintage" cider apple will have been bred to have a good balance of all three. If you can't them try mixing crab apples for tannin, dessert apples for sweetness and cookers for sourness. Try to avoid Bramley's which tend to break down on milling creating a mush which is high in pectin and can cause cloudiness.
Edit: it's also worth storing the apples for a few months, as its a whole lot easier to crush slightly soft apples compared to rock hard ones. Also this'll give you time to collect enough for a batch, and they may sweeten up a bit as well.
And don't be too hasty with collecting the apples, take them too soon and they wont have as much sugar content as if you'd left them.Traditionally you would wait for around half the apples to have fallen before you collect the windfall and the ones still on the tree.
2. pH (acidity ) is important as it is used to preserve the cider , adds flavour and helps reduce the activity of spoiling bacteria's and wild yeasts.
You can buy quite cheap indicator strips which you dip into the cider to give you an indication of the pH.
pH should be between 3.2 to 3.8
3.2 to 3.3 is acidic but should not need campden tablets
3.4 to 3.5 is balance but should need some campden tablets
3.6 to 3.8 Is Ok but will need more campden tablets to kill off bacterial
anything above 4 is likely to be spoiled by bacteria, you should reduce pH with Malic acid, as the amount of campden tablets is likely to be too high.
That said it's up to you, "farm house" ciders quite often are made as is...but they can be a bit rough. (due to wild yeasts and some bacterial spoilage)
(see
http://www.cider.org. for how many campden tablets to add per gal. for different pH's)
3. Original gravity (OG) is important.
below 1045 you should add extra sugar as the level of alcohol is likely to be too low to aid storage. You can add sugar solution. Again if your not planning to store the cider for long.....
4. To use yeast or not
Well true cider does not, BUT your not in control of the process,and your whole effort and time could be turned to vinegar. For novices I would say it's best to use pectinase to prevent cloudiness, to kill off wild yeast with campden tablets (see the link above it's amazing info on how many to add) and to use a good homebrew yeast . Last year I used Gervin no. 5 a champagine yeast.
When you add the campden tablets it's important to leave the juice over night to allow the level of sulphur dioxide to reduce, so that it doesn't effect your bought packet of yeast.
5. Traditional cider undergoes a second aging process which gives a rounder flavour. If you brew in a shed/garage at the traditional time of around November because the lower temps it will mean a slower rate of fermentation. Fermentation stops usually during Jan to Feb and starts again to finishing SG around March. This aging also converts malic acid to Lactic acid which gives a better rounder flavour.....BUT if you haven't used Campden tablets or got the right pH, this extension in fermentation can give the bacteria the opportunity it needs to spoil your cider (and you'll have a load of cider vinegar ). So it's completely up to you.
My cider was ready around end of March. I bottled it up with a teaspoon of sugar (it was brewed to full dryness ; SG 995 so I was not at risk of exploding bottles)
It has greatly improved the flavour, but because I could not get desert apples and used too many cookers it smells appley but is VERY dry with little appley rich taste. It's also lethal, I can drink strong cider but this stuff turns my ears red and I loose my legs after the second bottle!. Sounds great but it's too strong, I like to quaff.
