I know its a little belated, but worth showing off. This is the latest trend in cider making gear... it is actually very warm and waterproof:
Now, this was a Christmas present. I asked for (and I quote my words as closely as I can remember them); "Something that I can throw on to press apples - it needs to be waterproof and a jacket I don't care if it gets really dirty. 'Cos it will!". Somewhere in my parents head, this must have turned into "I am a farmer and I need a really nice new jacket, with matching wax trousers. I might even save it for best".
Needless to say, I have used it for pressing - as per photo above. And, who would have believed it - it got bogging with apple bits and juice. But then I hosed it down and it has come up really well. So I guess it was a result after all. Not sure I will be allowed to wear it for best though!
