A beer dispenser comprising:
- a coupling portion (A), a spout portion (B) and an air passage portion (C), all coupled together;
- said spout portion (B) comprising a cylindrical tube portion having a semicircular groove (13) extending longitudinally thereon, a partition plate (3) with a predetermined length extending rearward from the front end of said cylindrical tube portion, a main pouring port (1) being formed above said partition plate (3), an opening face (4) formed at said main pouring port (1) and being set to make an angle of 90.degree. or less with the axis of said cylindrical tube portion, an end wall (5) provided below said partition plate (3) at a position between the front end of said partition plate and the upper edge of said opening face (4) of said main pouring port, a hole (2) in said end wall (5) which forms said subsidiary pouring port, and the area ratio between the area of said subsidiary pouring port (2) and the effective area of said main pouring port (1) being in the range of 2 to 10%;
- said coupling portion (A) comprises a slightly tapered sleeve (16) having a rim (6) with a diameter larger than an opening of a beer container to which the dispenser is to be coupled, a press ring (9) surrounding the front end of said coupling portion, and a thin packaging (10) extending rearward from said press ring (9);
- and
- said air passage portion (C) comprises air intake port (12) which opens through said press ring (9) into said semicircular groove (13), and a tube (11) extending rearward from said air intake port (12).

- and
- said spout-like tube having a partition plate (3) therein separating said spout-like tube into said main pouring port (1) and said subsidiary pouring port (2), said partition plate being provided at the front end of said spout-like tube and extending rearward in said spout-like tube;
- said main pouring port (1) having an opening face (4) which is set to make an angle 90.degree. or less with the axis of said spout-like tube;
- the area of said opening face (4) being approximately equal to the cross-sectional area of said spout-like tube;
- the subsidiary pouring port (2) being considerably smaller in comparison with said main pouring port (1);
- and
- said subsidiary pouring port (2) having a front end which is situated behind said main pouring port (1).
