"Beer Gun" type devices can be a help (especially ones that inject CO2 into the bottle before the beer goes in - this displaces the air and insures that your beer will stay fresh in the bottle longer). Gonnecting to the tap does work but it is better if you connect directly to the keg as the art here is to avoid physically disturbing the beer to the point where gas starts to escape. The connection should be through a long, small bore line (choker) so that the flow rate is, even with full keg pressure, slow. The beer thus experiences a gradual pressure gradient as it flows down the hose and CO2 is less likely to break out. Nevertheless, bottle and growler filling is a challenge. The only way to completely control foam is with counter pressure fillin in which the bottle is pressurized to nearly the same pressure as the keg and the beer filled against that counter pressure.
