Wort Grant

A Wort Grant is a small collection vessel attached to the brewhouse and is placed between the lauter tun and the brew kettle. A wort grant offers several advantages, serving as a buffer between the wort flowing out of the lauter (or mash/lauter) tun and its entry into the boil kettle. Using gravity, the wort is gently drawn from the lauter tun, helping to prevent the formation of a vacuum or negative pressure. This reduces the risk of compacting the grain bed, which could otherwise lead to a stuck mash.

It also allows the brewer to see and assess the clarity of the wort so they may choose to pump it back to the top of the mash until it has become sufficiently clear before being redirected to the into the kettle tun.

The brewer is able to take wort samples from the grant at any time to conveniently measure the pH and gravity of the runoff and avoid over-sparging the grain.

Every PMG brewhouse is equipped with a high-quality stainless-steel wort grant (see photo below) for the brewer to be able to create the highest quality beer possible.
