Degas my sample!

[BucklandSwifty]

I have been helped enormously by the kind people on this forum for
which I ever grateful. I was advised by Andrew recently that I should
degas my sample of fermenting juice before I test with my electronic
ph tester. I have searched the group for degas but cannot find the
answer. As I am trying to lower the ph this years first batch I want
to get this right, is there a method to degassing other than letting
it sit open to the atmosphere for a period of time?

I think microwaving it might work, but I could be wrong.

What is "degas"?

Getting rid of dissolved gasses, e.g. CO2 which will make it appear more acid.

I believe you pop a small sample of your cider into a test tube and then
heat it up to drive off the excess CO2. CO2 is acidic so its presence will
affect any pH reading, particularly if fermentation is vigorous.

I did already answer you a couple of days back. I wrote:

"You may need to be bit more aggressive than that. Typically a sample of
cider is brought briefly to the boil to drive off the gas; or you can do
a few bursts in a microwave; or pour it back and forth which is rarely
so effective. If you heat it, let it cool before using your pH meter."

Sorry Andrew, I have a bad habit of looking at the emails instead of
the forum web page, I must have culled your response before reading
it. I have gone back to my post and read your advice. Now off to
have a slice of humble pie, probably Bramley!
