Here's a post that I made way back in 2009 when we were taking our first teetering steps into apple juice production. We've changed the temperature regime for the pasteurization a little but you should be able to get the gist of what you need to do from this.
Today Kaz and I took the youngest back to Aberystwyth for the final year of his course. As we were moving him into his new digs, I spied an apple tree loaded with fruit. A quick word with Robs landlord and we quite quickly had a boot full of apples to take home with us.
I'm not clued up when it comes to apple varieties but these were a fairly nondescript green eating apple.

When we got home, we managed to make four gallons of very pleasant tasting juice from them.
Now for something entirely different. At least for us anyway. So far this year, we've been freezing the juice that we've been making but now thanks to the arrival of a pallet of glass bottles and their tops, it was time to get our new pasturiser out of the box.
The machine will deal with thirteen bottles at a time. The idea is to fill the bottles with freshly pressed apple juice and very loosely put the self sealing lids on them. All in all, the half barrow of apples in the picture made 20 75cl bottles.

The bottles are then placed into the pasteuriser.


The pasteuriser is switched on and the water taken upto 77 degrees and kept at that for thirty minutes.
After this time the bottles are taken out and the tops tightened. The bottles are then laid on their side so that the hot apple juice actually pasteurises the inside of the lid.

This was our first effort at pasteurising apple juice and if we've gotten our temperatures correct, then the apple juice will have a long shelf life and wont try and turn itself into cider or go off.
I've still got to design some labels and find some willing guinea pigs to try the juice. :wine:
