The Warre's Late Bottled Vintage (LBV) was matured in wood during four years after which it was bottled without any fining or filtering. It was then aged in bottle for another six years in the Warre's lodge in Vila Nova de Gaia prior to being offered for sale. It is usual for Warre's LBVs to continue ageing in bottle in the Warre's lodge for a longer period than required by law, i.e. four years in bottle, after four years in wood. This prolonged ageing, first in wood and then in bottle is key to the development of the sumptuous nose and flavours that lend this Port a style and complexity akin to that of Vintage Port.
