McGuigan Simeon Wines, being Australia's third biggest listed winemaker, retains an impressive inventory of prestigious vineyards. To ensure quality of fruit is consistent for Bin 3000, winemakers spend a considerable amount of time amongst the vines. Grapes are sourced from various irrigated and dry land vineyards, harvested at optimum flavour ripeness throughout the cool of night. The must is vinified for several days at moderate temperatures. After primary fermentation, the grapes are pressed then clarified before being inoculated with malolactic bacteria. Once this secondary fermentation is complete the wine is assembled and matured in oak barrels prior to finishing, filtration and bottling.
