Peter surprisingly just said no…
I got it from someone else but agree nothing is published (however Brindisi have been an avgas gray area for years, with the actual conflicting with published data) so have emailed them. No reply received thus far, but it was sent in English only so maybe that’s why 
There is a report from a year ago stating they had avgas.
As mentioned, a call to Corte LINB to check if avgas could be taken on would be little effort and it is in the right spot. Sure the runway is soil, but it is the best soil runway I’ve seen and since it is already used by a TB20.
