@Miraculix: I struggled to find reference* to recent "smoking" of Brown Malt, but it is a more recently accepted view. The problem you can come across is writers viewing history through a telescope: "brown malt is smoky", or "brown malt is carefully made so it's NOT smoky". It's actually all those things but depends on what bit of history you look at. Look back far enough (not too far!) and there is no brown malt ... just "malt" at whatever colour it comes out. This is fairly recent (2022) from Ron P. (from
Last bit on malt 1880 - 1914):
He's also talking about the common practice of the period (at least by French & Jupps who supplied Whitbread and much of London at that time) of intentionally "blowing" or "popping" grain (torrified). Never tried it, but makes it much lighter, causing confusion when malt was measured by volume, not weight. Ron adjusts his recipes to be weight orientated, many writers do not, hence discrepancies!
Note the bit "Not left on the withering floor as long as other malt" ... that means it was kilned damp (like "Munich" malt and crystal malts). The last bit of that snip is also valuable: "generally dried in wire <rotating> cylinders".
All came to an end (because of fire risk) and all Brown Malt is now dried/kilned in enclosed kilns ... no smoke, much more uniformly darker, and no enzymes. A very different product to "traditional" Brown Malt, and the reason I'm always whinging about folk using "modern" brown malt (and "amber" malt) willy-nilly in historical recreations. And "no", modern stuff is not close at all to historical Brown Malt ... I say that, before anyone starts claiming it is!
* I've tried "cataloging" stuff, but me distorted brain never remembers where I catalogued it, whether I did catalogue it, or where I've put the flippin' catalogue! These posts have to be my "Catalogue" ... well, it works for a short period.
