What’s the advantage of using the "inverted method" with the AeroPress?

People who use the inverted method do so to prevent any premature drip-through of their coffee and to give them complete control over usually longer brew times. If you want to use a long brew time, we recommend using the normal method but insert the seal on the end of the plunger a half inch or so into the top of the chamber to stop drip-through while waiting for your longer brew time. The seal stops drip-through just like putting your finger on the top of a straw stops dripping out of the bottom of a straw. We think shorter brew times brew better tasting coffee but taste is certainly personal and people should brew their coffee the way it tastes best to them. Be advised that using the inverted method may increase the risk of spilling hot water and the risks associated therewith.
