Subject: Pectinase and clarification on a pasteurized must

Hi,
I am a newbie cidermaker. I just started experimenting with cidermaking at
the beginning of 2016, with pasteurized, store-bought juice-which was really
the only option in January. Now that apple harvest has finally arrived, I
just started my first batch using a fresh, raw must (on which I am
attempting a wild-yeast fermentation on a partially sterilized must--half
dose of sulfite).
My question is about the use of pectinase for clarification on pasteurized
juice. What I found (on my first 7 experimental batches-with a pasteurized
juice) is that even with the recommended dose of pectic enzymes prior to
fermentation, my cider never really got clear. I know that Jolicoeur warns
that you have to be very patient, but I left it in secondary for (nearly)
four months. It didn't look much clearer than it did at the start of
secondary (and it had long ago fermented out all of the sugars;
unfortunately, I ended up with a lightning fast fermentation on those early
batches). I finally just gave up on it getting any more clear and bottled
it anyway.
In contrast, on my new batch using a fresh, raw juice, I noticed that it
seems more clear in less than one week than the cider I kept in secondary
for almost four months!
So, I am wondering if there is something about the pasteurization process
that interferes with the ability of the pectic enzymes to degrade the pectic
substances? Does anyone have any idea whether that is a tenable hypothesis?
If not, perhaps I need to get a better pectinase blend that is optimized for
apples? (I am just using the generic pectinase I got at the brew store.
But, I suppose that is not optimized for apples.)
I haven't attempted a complete debourbage (with the addition of a fining
agent), but I did do a little experiment where I tried a double dose and a
triple dose of pectinase on a small amount of the pasteurized must just to
see if dosage might have any effect. After four days at room temperature, I
couldn't tell any difference between the two test subjects in terms of the
clarity.
Truthfully, I don't really care if my cider is not perfectly clear because I
know it doesn't affect the taste. My interest is more academic: I just
would like to understand what is going on and why. My family has been
making fresh (unfermented) cider for nearly 100 years, and they don't seem
to have ever had a problem getting it to clarify. Of course, they don't
pasteurize their juice and they are not fermenting it. Could the
pasteurization be part of my problem? Or maybe the haze is not a pectin
haze at all. But, I tried 3 different pasteurized juices (2 organic, 1
not), and had pretty much the same experience with all of them.
I don't know if this digest can accommodate pictures, but here is picture of
my first batch four months after the start of fermentation:

Now here is my most recent batch on a fresh, raw must (100%
Gravenstein-which is all you can get in Sonoma County, CA at this stage of
the harvest). It hasn't even started fermenting yet (I just started it less
than a week ago). I think this new batch looks pretty already.
Cheers,

P.S. Thanks to Claude Jolicoeur for publishing your wonderful book. It is
worth every penny. I currently treat it as my bible.

Hello cider folks,
I have been making a very dry cider from the random apples I've been
gleaning throughout the Bulkley Valley for the last ten years. Now I'm
getting serious about bear-proofing my garden. This will require four
strands of barbed wire at 10,000 Volts in addition to the 2 m high deer
and moose fence I already have.
What should I plant? I live at 55 degrees latitude in north central
British Columbia, Canada. This is officially Zone 2, but we grow all
kinds of apples and even some cherries around here. This year, we have
grown some sweet corn. Forsythias do well as does basil in sheltered
south facing spots.
Do you have advice on apples I should plant for cider?
Thank you for your help.
