UK Stout adjuncts 1969 - 1973

And here are the adjuncts. The final piece in the grist puzzle. A little unexpected, too.

How disgraceful! Only the Boddington and Truman versions contain roast barley, as a Stout should. Hadn’t the brewers read the style guidelines? (Certainly not.)

It’s interesting that, although there are four different adjuncts, all are types of barley. The roles they play aren’t all the same. The roast being for colour and flavour, the torrefied for head retention, the meal and flakes for economy.

I was surprised at the absence of maize amongst the adjuncts. That was the classic adjunct for the first half of the 20th century. Only disappearing during the two world wars, when it would have needed to be imported.

Which makes it a bit odd that in the 1970s, when there were considerable quantities of maize being grown in the UK, that brewers should eschew it in favour of barley. 

Neither Adnams nor Elgood used any adjuncts at all.
