I’ve just started making cider for my wife. I’ve done two batches so far. I’m kegging them. I have a question.
Before back-sweetening I have been pasteurizing the fermented cider. I heat it to 160F and hold for 10 minutes. I don’t have any of the chemicals typically used to kill yeast and this is pretty easy. The two ciders I have made taste great. I don’t see much if anything about this method online.
Is there an advantage to chemical pasteurization (sulfites/sorbates) over this heat method?
I have recently attended seminar about N/A beer and there was a little bit talk about pasteurization.
Now this is what I recall.
Pasteurization is measured in PU units.
Let say 1 min at 175F can achieve the same PU as 30 min at 140F. (You would have to find exact time and temp by yourself)
You should pasteurize the packaged product (can, bottle, keg).
Higher temp / less time will get you better results (taste wise) then lower temp / more time.
Now how to pasteurize final product if you do not have pasteurization tunnel?
You could do it in home canner for bottles and cans and boil kettle if you have keg.
Word of caution be extremely careful. Wear PPE. 175F water can cause 3 - the degree burns and that is not fun at all.
