Entrepreneur Bobby Gattuso believes beer drinkers shouldn’t be limited by the choices on tap or at their local liquor store. That’s why he launched Hop Theory, a startup that aims to “bring brewing to the bar” with a lineup of teabag-like sachets.

The idea is simple: Steep the spice mix of your choice in your pint to release a variety of flavors.

But does it sound a little too good to be true? Though Gattuso’s Kickstarter campaign has nearly met its $25,000 goal with two weeks to go, we remain unconvinced the product can do what it sets out to.

Why? Well, it has to do with the science of brewing beer.brewing beer.
