This is the first post in what will probably be a long series. As I told you, I've the full set of Whitbread Porter logs. It's time to put them to use.

Where to start? How about at the beginning. These numbers are taken from the earliest of Whitbread's records to survive. They're from a particularly important period in Porter's development. When the Napoleonic Wars were still raging. And the extra taxes imposed on beer to pay for the war put brewers under intense pressure to cut costs.

The easiest ways to cut down expenditure on malt was to move away from a 100% brown malt grist to a mix of pale and brown. It may have made the beer cheaper to brew (a gravity point from pale malt cost less than one from brown malt), but there was one little problem: the colour. Various things were used to darken the colour: burnt sugar, liquorice juice, concentrated wort. But, when the law on brewing ingredients was tightened in 1816, making sugar, among other things, illegal, brewers had to find a replacement.

Just one year later, in 1817, it arrived in the form of Wheeler's patent malt. Malt that was roasted in a drum to give it a very high degree of colour. Being malt, it was perfectly legal for brewers to use. You'll see below just how quickly Whitbread adopted it.

The amount of black malt in the grist was initially very small. Less than 1%. That would change later. But I don't want to get ahead of myself. That will be the subject of further posts. As I investigate Whitbread Porter in my trademark ridiculous level of detail.https://blogger.googleusercontent.com/tracker/5445569787371915337-2851164586059218826?l=barclayperkins.blogspot.com
