Red wines from 2009 present high levels of sediment
Before you ask, I’ll explain what is the photo showing: it is the bottom of a 10.000 liters bin where one of the components of Oscar’s 2009 was resting since November. After aging for some months, this wine created a compact cover of sediment, which this year is specially bigger due to two facts: very cold Winter (resulting in more and denser precipitation) and high level of anthocyans (pigmentation substances responsible for the color) in the grapes of the last harvest.
It is interesting to compare this photo, of a still red wine, with other of a Rose Port, where the bottom of the bin is covered by a much thinner and pink layer. Different levels of extraction lead to different types of sediment!
