Just after my MLF I racked my wine to clean containers. As I didn't have enough to fill another carboy, I allocated the wine to various 10L, 5L and 2L containers.
The variety is Sangiovese. It's winter here in Australia and just about a month ago I noticed the formation of a white film accumulating at the top of each container. It appears to be powdery in nature with some granular bits adhering to the neck of the glass.
The containers are topped right up with bearly 10-20mm to the underside of the bung.
Can someone tell me what this is and why it has formed. Also will it impact on the quality of my wine.
