Porron. I just found one of these at Goodwill. Have been using it for a balsamic vinegar cruet. It's real use is much more interesting: "Hold up towards the mouth, but never touching it, and tilt to produce a stream of wine. Then move it away to arm’s length and swallow without closing your mouth. Stop drinking with a quick twist of the wrist or any hesitation will leave a trail of wine down your shirt front. For first time users, we recommend a bib."
