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 salts with the tartaric acid: Potassium bitartrate and the neutral calcium tartrate at the pH of the wine. For these, when their solubility threshold is reached, they settle and contribute to de-acidify the wort. In the southern regions where acidity is sometimes a little lacking this may be a cause of failure of extra acidity. White wine is made from white or black grapes (but always with white flesh, the grapes with coloured flesh are called "Teinturier" meaning coloured juice). Once harvested, the grapes are pressed and only the juice is extracted which is called wort. The wort is put
