Quite so. From a barrel, preferably by gravity. However if not, via a beer engine which does NOT use any gaseous infusions.
And now, consequent of consuming beer sourced from a mechanism which didn't use any gaseous infusions; I must make a gaseous exfusion..................................ahhhh; that's better!!
Not always true, unless you know somewhere that still sells Party Sevens. There are some great beers in larger bottles now - such as Goliath (Wychwood brewery). Plus if you like stuff like wife beater, they do that it a litre bottle.
