To heat or not to heat, that is the question

I am purchasing 5 Gallons of fresh pressed unpasteurized cider from a local orchard. It is treated with UV rays. Do i need to heat this to kill off any unwanted yeast strains or will the UV take care of that for me. Thanks

The answer is quite simply to not heat. Just add some campden tablets if you want...

Only heat if you want to make apple jelly.

The UV will kill any wild organisms, so you dont need to heat or add campden/k-meta (I wouldnt do either for unpasteurized juice either)

After the fermentation is done, if you are planning to keep any beyond 6 months or so, you can add a half a dose of campden as a preservative - but dont add it to anything that you are planning to drink in the next 6 months because it will leave a bitter aftertaste that takes several months to fade

thanks for the information. I will plan on just pitching the yeast into the cider and calling it a day
