Avoiding Common Distilling Mistakes

Distilling is as much art as it is science, and sometimes the best lessons come from missteps. A few common mistakes tend to trip up both newcomers and experienced distillers alike. One big one? Rushing your cleaning routine. Residue can affect flavor and lead to contamination. It’s critical to develop a thorough cleaning checklist and stick to it after each run. Something as minor as a forgotten rinse can compound over time into off flavors and reduced yield.

Another common issue? Ignoring your cuts. New distillers may rush this process, but understanding the differences between the heads, hearts, and tails is vital. Skipping proper cuts can lead to unwanted compounds in your final product or diminish the spirit’s clarity and smoothness. Some experienced distillers mark their optimal cut points with temperature logs and sensory cues so they’re never guessing.

Heating source matters more than people expect. Uneven heat from a poorly controlled source can create hot spots that scorch your wash or force vapors too quickly through the system. A properly sized and maintained heating element or boiler ensures consistent performance across batches. Make sure you're also matching your heat source to your still’s size and design.

And yes, gaskets. Overlooked but essential. A loose or degraded gasket during a run can not only cause vapor leaks and inefficiencies but also present a safety hazard. Inspect them regularly, especially after high-use runs or long idle periods.

Other small but costly errors include poor record-keeping, skipping test runs on new equipment, or even underestimating head space in your fermenters. Most of these mistakes are avoidable with regular maintenance, clear SOPs, and a little humility to learn from others.

As one long-time distiller put it: “Every mistake costs money. But the ones you make twice cost twice as much.”
