Cabernet sauvignon pressed, juice racked etc. 1 x 11 litre carbohydrates and 1x 1 imperial gallon DJ.
The other 3 x 11 litre carboys are the Primitivo, Merlot and Shiraz. The 1 & half gallon DJ's are the excess from the racking of the P, M and S. I expect another drop of sediment from them, as the 3 x 11 litre carboys were carefully racked, whereas the blended bits are from closest to the lees.
I don't know if you can see from the picture that the sediment in the cab is dropping out already.
