typos and ref formatting in barrel storage
====Storing empty====
Burning sulfur sticks/wicks or disks. For the preservation of empty barrels or other wooden vessels, burn 4 g of sulfur per hectoliter of capacity and repeat every 40 - 50 days <ref>2016. Laffort sulfur disc instruction manual. South Africa</ref>. To use disks, use a disk holder <ref>(e.g. [http://www.gwkent.com/sulfur-disque-holder-for-barrel.htmlGW Kent sulfur disk holder]</ref> or create a wire hook to suspend the sulphur disc in the barrel. Light the disc and place into barrel, inserting a bung to prevent the SO<sub>2</sub> gas from escaping. Leave to burn for a few minuted minutes before removing and bunging the barrel for storage.
'''Note: Do not burn sulfur in used spirit barrels, as there is a risk of explosion.'''
