+\noindent
+Mit dem Dreieckstest kann man feststellen, wie gut ein Geruchs-
+oder Geschmackstester verschiedene Gerüche oder Geschmäcker
+unterscheiden kann.
+Seine wahrscheinlichkeitstheoretische Erklärung benötigt die Beta-Funktion,
+man kann die Beta-Funktion als durchaus als die mathematische Grundlage
+der Weindegustation
+bezeichnen.
