HISS

A 2005 brought on the market new closure for wine bottles in the fight against the dreaded corked, HISS stands for Hermetic Internal Solid Seal. This patent registered seal was invented by the German engineer Ludwig Hiss and was popularly referred to as "Verhüterli". The closure consists of a normal one cork whose underside is covered with a thin tin foil. This film prevents molecules such as the cork taint TCA (trichloroanisole) and related causative agents of the wine error from the cork into the wine. Pure tin has been used successfully in the food industry for many decades. The metal is food safe and resistant even to aggressive substances such as olive oil or Coca Cola. The inventor has also developed an easy-to-install auxiliary unit for the automatic closure machines. This part puts the Zinnhütchen over the cork before it is pressed into the neck of the bottle. When uncorking the bottle, the cap slides out without problems with the cork. HISS is from the basic idea similar to the alternative system ProCork, See also below closures,
