Tuesday, June 28, 2005 To avoid excess foam when pouring soda into a glass, pour slowly enough so that air can flow into the bottle even as the soda pours out. If you pour too fast, the bottle "gulps", alternating between soda going out and air coming in. This turbulence stirs up the carbonation, causing foam. When pouring beer, tip the glass and pour the beer on the side so it flows gently to the bottom without falling too far. Again, this is to avoid foam-generating turbulence. |
