I guess lots of you agree, seeing as that spells out IPA. As it does in this advert from 1950:






Banbury Guardian - Thursday 23 March 1950, page 2.

What was that beer like? How strong was it? What colour? They're the questions I always asked when I was adverts like this. I never expected to get answers. But I did. Thank Whitbread.

The Whitbread Gravity Book is one of the most valuable sources on 20th-century UK brewing. Without its thousands of ananlyses, I'd have no idea - and no possibility of ever discovering - the details of the beers from brewery's whose records are lost.

The colour numbers in the Gravity Book are particularly helpful. Brewers mostly didn't record the colour in their brewing records. Nor all the colouring sugars they added post-fermentation. Many of the recipes in my new book came out way paler than the Gravity Book analysis. I've adjusted the recipes accordingly.

Multiple sources. Combining them to make something greater than their simple sum is my ultimate joy.

Here are those NBC beer details:
