Adding to what Smurfe said,
I also tip the carboy but let sit tipped for at least 24 hours,
preferably more before racking. I have a MM Chianti tipped and waiting
for just that operation at this moment. I plan to rack tomorrow
night. The fact is though, that I lose more than I would like but still
don't top up. I use an inert gas cap in the head space. So,
overall, I figure the yield is 28 bottles per kit.
