Beer Bottle with shoulder

A 500ml (half litre, approx 1 pint) brown glass strong beer bottle.

These glass bottles are sealed with Crown Caps, and require either a hammer-on or two-lever Crown Capping tool, as well as a supply of Crown caps.

Alternatively, they can be sealed using the re-usable plastic beer bottle stoppers that do not require any tools to fit. (These plastic caps do not seal as efficiently as the metal 'Crown' caps.)
