Not all bottles are created equally. Bargain bottles that can be picked up from the supermarket typically do not have a lot a sediment at the bottom because they are usually fairly young bottles. Bottles that do not have any sediment at the bottom are made to be enjoyed to the very last drop, and that’s why some companies include a soft straw that will be able to pull up every drop. Older bottles have more sediment at the bottom, and users typically aren’t very interested in drinking what is at the bottom of these bottles. For those cases, users are going to want to utilize one of the harder straws to leave everything that settles in the bottom of the bottle rather than in your glass.
