I know it's a side question, but why do you WANT to keep bubbles/foam?
While I enjoy seeing the bubbles as a sparkling cider is poured, and I know
it releases aromas, I don't see the point in a mousse/head hanging around.
And, having judged a lot in the past, I'd be slightly suspicious of a cider
which held a head: Why should it? I wouldn't (necessarily) mark it down
for that alone, but I'd be on the alert for faults which might cause it not
to dissipate as is usual.
That said, you could investigate "heading agents" (or "aids") to achieve
what you want. Look to a brewing supplier.
