4 Inch Agitation Port Upgrade for Copper Stills

Thick, grain-heavy mashes love to settle and scorch on the bottom of a still, ruining a run with burnt flavors. This 4 inch agitation port is a professional-grade upgrade that gives you a dedicated opening to stir the charge while it heats.

Keeping the mash moving spreads the heat evenly and prevents solids from caramelizing against hot copper, which is especially valuable when distilling on the grain for whiskey or running heavy fruit and molasses washes.

Made to integrate with copper moonshine stills, it is a worthwhile addition for the hobbyist who wants cleaner, more reliable results from demanding mashes.
