- Every wooden barrel in which spirit under bond has been stored in a warehouse must be grogged with water immediately after it has been emptied. Instructions for grogging are given in the Technical Excise Manual. The weak liquor obtained by grogging may be used for reduction of spirit or found to be very dirty, kept in a separate vessel for examination by superior officer, who may either send it to the distillery for re-distillation or may destroy it, if the quantity is small and if the contractors agree to it, by pouring it out on the ground. The action taken by the superior officer should be noted in the Inspection remarks book.In order to bring the grog into the stock account a cask should be set aside for storing groggings and this should be treated as vat. A separate vat register should be opened or a part of one of the vat registers may be set aside for recording the details of receipts and disposal of its contents.The vessel used for holding the grogged liquor should always be kept in a fixed place in the warehouse. If it is an ordinary cask kept lying on the floor it should be painted clearly with the words -(1)"Grogged liquor";(2)Capacity;(3)Bung diameter;(2)and (3) should previously be ascertained by actual measurement.Maintenacne of Registers in Warehouses
