Treat or nightmare. I've one of them for you today. Which it will be, depends on your attitude to detail.There's going to be lots of that. If you're the more superficial type, I'd bog off now before you get bogged down.

Ever since I dragged the family to Glasgow to spend some time with the Scottish Brewing Archive, I've been planning a series of in-depth comparisons between English and Scottish beers and brewing practices. This is part one.

It's taken me a wee while to lasso and tie all those pesky numbers. More than two years. But the wait has been well worth it.

In the interests of fairness and coming up with results that actually have some effing meaning, I'm comparing like for like. That is, beers in the same style and with similar gravities. Not that there's a heap of variety in this first set. All I have from Younger are Shilling Ales. It'll get more complex as we progress through the 19th century and Younger's range gets ever broader.

It says something about early 19th-century beer strengths that only one solitary, single example we'll be looking at today is below 1070º. Nice Cooking Milds.

I guess you want me to kick the teeth out of that? Sorry, I meant pick the bones out of that.


Don't read anything into 60/- equating to X Ale, or ordinary Mild. That's pure historical coincidence.

Based on the standard bolleaux written about Scottish beer, I'm concentrating on three areas:


hopping rate
boil length
fermentation temperature

Which, according to the standard story, should be low, low and long for Scottish beer.

Let's go through them in order.

The Younger's beer is on average about 50% less heavily hopped than the London beers. There's only one English beer, a Truman's X Ale, that contains fewer hops.

Oh look at that! The Younger's beer has a much shorter boil than any of the English beers. None of them was boiled for less than 2 hours. The Scottish beer is, on average, boiled for more than an hour less.


According to Roberts (an other sources), Scottish beers were pitched on average around 10º F cooler than English beers, usually around 50º F. You can see that all of the Younger's beers were pitched at a greater temperature than that.
