Long Bottle Necks
Beers come with long bottle necks, but why is that? It lets you hold your bottle comfortably for long periods of time. This also lets you pour it into a glass or mug without any hassle. It also distributes heat throughout the container. Unfiltered beers have more bulbous necks to catch sediments.
Can Tabs
We have already talked about bottles, but what about cans? Those tabs can get annoying when they fall into your drink. You will never guess why they are there in the first place. Apparently, they were added to hold the straws in place! In general, this is no longer necessary since no one uses straws for cans.
