Milling - Converting Malted Barley Into Grist

[@MrChristopherMolloy]

A great series Erik, thanks for sharing ✌️

Outstanding series. The reason only Inchdairnie and Teananich utilize hammer mills (as opposed to roller mills) is that they are the only two Scotch malt distilleries that utilize mash filters instead of traditional mash tuns. As the video describes mash tuns require a fairly specific (and relatively coarse) grist distribution that also leaves most of the husk relatively intact. Anything finer presents the risk of slow wort collection and sparging, poor extraction and even "stuck" mashes as they rely on the husk as the filter medium, and gravity, to separate wort from the mash following conversion. Conversely mash filters, which are relatively new technology, can handle grist that is much finer with significant flour employing filter screens with a very high surface area and filtering potential, and pressure, to separate wort from the mash. Mash filters are highly efficient compared to mash tuns but are relatively expensive to purchase and require skilled operation. Mash filters can also handle a wide variety of grain types and conditions (Inchdairnie) as well as other starch sources, including raw (unmalted) grains as are common in grain distilleries.

I operated some mills like those back in 1988. One a hammer and the other one a stone mill. Making flour.

Hammer mills are also used in making flour for bakeries.

Hi, what about Waterford with a wet grinding mill?)))

[@ErikWaitWhiskyStudies]

Waterford isn't in Scotland. There are other variables that could be mentioned, such as those used on the USA, Canada and Japan. This series focuses on SCOTCH Whisky production, particularly MALT whisky. I'll do another series on Scotch Grain Whisky after this series.
