After fermentation the wine is kept in the same tank for two months at 8 degrees centigrade at low sulphur levels for yeast autolysis. This process let the yeast cells break up and let all the flavours they extracted during fermentation released back into the wine. The low temperature is to keep any live yeast cells inactive and as a preservative measure for the wine. Therefore the low sulphur levels.
The wine settles here naturally clear because of the cold stable conditions. With the Full Moon at Easter, which is normally six weeks after the last wine finished fermenting, we taste the wine to decide what we are going to use in the big blend. With Full Moon all the flavours on the nose is much more pronounced, because the moon “pulls” the flavour out of the wine.This gives us a sneak preview of what’s to come in the bottle with age. . Wine also tends to be more murky, or less collaidal stable at these times. With the New Moon after Easter ( 17 days later) the wines are then racked off their thick lees because that is when they are at its most collaidal stable again. The lees are most compact at this stage and the wine can be racked very cleanly which means less filtration before bottling.
