Minerality - the debate continues
There has always been a continuing debate about minerality in wine and whether it exists. An Institute of Wine seminar has now refuted the fact that minerality is not related directly to any sort of nutrient mineral uptake by vines. Alex Maltman professor of earth sciences at Aberysthwyth University outlined the disconnection between geological minerals and the mineral nutrients - elements - required by vines, of which there are 14, pointing out that these 14 are not the same minerals as geological minerals. Minerals do not vaporise, they are odourless and their concentration in wine is far below the taste threshold.
