The logical status of these propositions in Wittgenstein's investigation, including their relation to physics, was discussed in Jonathan Westphal's "Colour: a Philosophical Introduction" (1991). Although "Remarks on Colour" is considered difficult on account of its fragmentation, his last work,
White wine a matte finish to the colour of the grape and contains the yeast responsible for fermentation. The grape skin also contains volatile compounds in its deeper layers. These are responsible for the aroma of the grape and for the molecules that become the aroma of wine during fermentation: they are the "aroma precursors". In red grapes the film also contains anthocyanins or coloured matter which is from bright to purplish red. To produce white wine from red grapes it is necessary not to macerate the grapes, nor to press too hard on the harvest to avoid the dissolving of the
