We recently introduced a Limoncello to our line up that has been very well received. We are on our third batch, the first batch had no issues, batch two and three had the issue. This being that once bottled, we are seeing lemon oils (we assume) breaking out of solution and forming a layer on top of the limoncello once bottled. There is no layer floating in the bulk tank we are bottling out of, so we are led to believe something is occurring during bottling.
It is a simple set up, bulk tank with screen gasket to catch any larger chunks of zest. We were then going thru a cartridge filter setup that all our spirits get. We thought maybe this was the culprit, but after removing it, the same issue persists. Bottle filler is an Enolmatic.
The layer forms within 30 minutes max of botting, and if bottle is vigorously shaken, it reappears in the same timeframe. Any thoughts other than a "floating oil in natural" sticker?
Thanks
