The Ideal Glass Angle When Pouring A Beer

An average of 5% of poured beer is foam, but the glass angle affects foam amount. Testing showed a 55° angle produced the least foam (4.48 ± 0.20 cm), 59% less than 90°. Foam also dissipated fastest at 55° (0.090 ± 0.024 cm/s), nearly twice as fast as at 90°. Thus, 55° is the optimal angle to minimize and speed foam reduction.
