Here's why it matters to your experiments. A leaking seal does more than make a mess. It lets vapor escape before it reaches the condenser, which throws off your temperatures and your yield, and escaping vapor near a heat source is a hazard. With a cap that seals reliably, the only variables left are the ones you choose to control: your heat, your charge and your cuts. That's when distilling starts to feel like real science. Remember that owning a still is legal in the US, while making spirits calls for federal TTB permits.
