As you view the bottling room from the shop/tasting room you can see:
The 'Hydro-press'. This is the wooden-slatted barrel-shaped object, which is used to squeeze the grapes to produce the grape juice.
Through the right-hand doorway is the laboratory table where the various tests are carried out on the wines. Tests are made to ascertain the acidity, sulphur levels, sugar levels and alcoholic content of the wines prior to bottling.
On the far right of the Bottling Room are three 'Holding' Tanks. The wine from the fermentation tanks in the winery building is pumped into one of the Holding Tanks prior to bottling. At this stage, the wine is tested and the flavour, acidity level and sulphur levels are all assessed and adjusted according to requirements.
The wine is then pumped to the 'Plate Filter' which is a coarse filter made up of a series of filter plates. The number of plates used varies according to the type of wine being filtered. From the Plate Filter the wine is pumped through a series of two 'cartridge' filters. By the time the wine has passed through the second filter the wine is totally sterile, which gives it a very long shelf life.
The wine is then pumped to the 'Bottling Head' where six bottles at a time can be bottled.
Two bottles at a time are taken from the pallet of bottles on the left hand side of the Bottling Room and placed upside down on the twin heads of the small sink which can be seen on the left hand side of the table housing the 'Capping Machine'. Powered by the compressor underneath the table, the Bottle Washer squirts a sterilising solution into the bottles to ensure their cleanliness. The cleaned bottles are placed underneath the arms of the Bottling Head (stored off the machine in a sterilising solution) where six are filled at a time. The filled bottles are then placed individually on the 'Screw-Capper' machine, which is capable of capping 600 bottled per hour, although Mike is only capable of some 300 per hour!
The capped bottles are then quality-checked and labelled prior to being placed in crates and transferred to the winery where it is stored in large metal cages until sold
Labels are produced at Cwm-Deri using pre-printed backgrounds, which are then over-printed with the individual wine details. This enables any quantity of label from 1 upwards to be produced as and when required. The labels are applied to the bottle using a specially-designed label-applying machine.
