The tasting glass (1), of the type including a parison (2) generally being rotationally symmetrical around a vertical axis, includes within the parison (2) a set of at least two internal ribs (7) evenly distributed on the periphery of the parison (2), extending in a substantially vertical plane, almost from the bottom of the glass, up to a height of the parison (2) lower than the normal filling level of the glass, different for each of the ribs (7). The tasting glass also includes a dome (8), called “nose-cap”, located on the axis of the glass at the bottom of the parison (2). The ribs (7) each have the shape of a propeller blade surface. A method for producing the glass is also described. |

1. A drinking glass comprising:
a parison generally being rotationally symmetrical around a vertical central axis, with a smooth arcuate inner surface running from almost the bottom of the parison toward a rim of the parison,
the smooth arcuate inner surface comprising a first portion corresponding to the bottom of the parison, and a second portion, adjoining the first portion, corresponding to an upper part of the parison extending toward the rim of the parison,the first portion having, in a plan comprising the vertical axis, a first inner radius of curvature,the second portion having, in a plan comprising the vertical axis, a second inner radius of curvature, smaller than the first radius of curvature; and within said parison, a set of at least two internal ribs evenly distributed on a periphery of the parison,
each of the internal ribs extending substantially along a generatrix of the parison, almost from the bottom of the parison, up to a height of the parison lower than or equal to a predetermined level of the glass, different for each of the internal ribs,each of the internal ribs including a first end in the vicinity of the bottom of the parison and a second end opposite to the first end at the height of the parison lower than or equal to the predetermined level of the glass, a length of each of the respective internal ribs defined from the first end to the second end of the respective rib, a respective vertical plane passing through the entire length of the respective internal rib and the central axis of the parison. |
