The correct shape of the glass directs the main flow to those areas where the shades of taste will be perceived with greater force.
A wide glass allows you to drink in small sips with your head in an average position.
A narrow glass will make a person throw back their head. Throats enter different taste zones.
Most importantly, the glass must be heat-resistant, there must be no bubbles in it, the walls must be smooth, perfectly even. Not bad for wine glasses and crystal.
The right glass should have a high stem to make it comfortable to hold (you know that a glass should be held by the stem, not by the bowl).
The shape for red wine can be of two types: tulip and spherical, for white wine only in the shape of a tulip.
The red mold is designed in such a way that the wine reaches the sweet taste receptors located on the tip of the tongue.
For strong and tannic wines such as Cabernet Sauvignon or Merlot, it is preferable to use larger glasses - from 500 to 850 ml.
This will allow the wine to develop as much as possible.
For light and fruity wines such as Pinot Noir or Beaujolais, smaller glasses are suitable - from 350 to 500 ml.
