Double Diamond beer
Double Diamond was a beer with a split personality. It was first brewed as a bottled India Pale Ale (IPA)(*). In the 1950s Double Diamond was Britain's best-selling bottled beer. It was also one of the most successful draught keg bitters of of the 60s and 70s. Many people will remember the tag line "Double Diamond works wonders".
The origin of Double Diamond
It is difficult to pinpoint the exact origins of Ind Coope's Double Diamond. Ind Coope first used the name 'Double Diamond' on a bottle in 1936. It comes from a symbol of two interlocking diamonds which Ind Coope used on its IPA barrels.
According to Ian Webster, Double Diamond was probably a combination of two IPA brews, Ind Coope's own IPA and that of Samuel Allsop. The two breweries merged in 1934. In 1938 the merged business produced one IPA called Ind Coope's Double Diamond.
Double Diamond works wonders
The famous tag line was originally "A Double Diamond works wonders". It was first used in 1949. It referred to the bottled IPA and not the keg bitter, which came in the early 60s.
The tag line was part of a marketing campaign, along with a bowler hatted character called 'Sir Little Man'. There was a series of phrases:
- A Double Diamond strengthens your hand
- A Double Diamond puts you on your feet
- and ... A Double Diamond works wonders
In 1959 Ind Coope claimed that Double Diamond was Britain's best selling bottled beer . It was also the Duke of Edinburgh's favourite brew.
Double Diamond draught
Bottle beer sales boomed in the 1950s. But in the 60s a new beer was taking the lead. Keg bitter was becoming the choice of Britain's beer drinkers.
In 1961 Ind Coope merged with Ansells and Tetley to form Allied Breweries. The following year Ind Coope launched Double Diamond Draught. It was, like Watneys Red Barrel and Flowers Keg Bitter, a pressurised keg beer.
Ind Coope sold Double Diamond Draught alongside bottled Double Diamond. It was a phenomenal success. In 1964 sales of Double Diamond Draught doubled.
Alongside the new beer there was a new advertising campaign by the advertising agency Hobson Bates. They dropped Sir Little Man and the 'works wonders' tag line. Double Diamond was now 'the beer the men drink'. The first campaign featured a 'Double Diamond Club' which you could join in your local. This was follwed by a James Bond theme similar to the Milk Tray adverts. Advertising only to men was considered fine in the early 60s, as women made up only 1-2% of the pale ale market. 
By the end of the 60s the 'works wonders' theme was back: 'Double Diamond works wonders, so drink some today'. Along with 'he's only here for the beer...it's Double Diamond'.
In 1970 Bass Charington was Britain's largest brewer. Allied was number two and more profitable.
From the brewers' point of view it is easy to see why they pushed keg. Keg was consistent in flavour and appearance. The brewers became national brands through mergers. They were able to back their keg bitters with national advertising campaigns. At least until the mid 70s it worked.
The Daily Mirror ran a series testing the quality and flavour of beers in 1972. They found it difficult to understand the popularity of keg. But bottled Double Diamond was the only national beer to maintain its quality, strength and original gravity (OG). But their pick for best IPA was Green King's Abbot Ale.
These statistics show that Double Diamond draught and Double Diamond bottled were not the same.

In the late 1970s keg beer's popularity was waning. Allied pushed bottled Double Diamond in a series of national adverts in the late 1970s which stressed the beer's heritage.
The last advert I can find for Double Diamond is from 1981. It shows travellers returning from a bad flight into a rainly Luton airport. But one man has a smile on his face as he contemplates a glass of Double Diamond - 'Double Diamond still works wonders' ;-)

About 20 years ago I thought Belhaven St. Andrews ale was the best beer I ever had. It was imported to the U.S. at the time in bottles. I happened to be in Melbourne, AU once and stumbled on a pub. It was very much in the traditional pub style. Darned if they didn’t have St. Andrews on tap. But they also had Double Diamond on tap. Decided to compare so tried DD first. It was fantastic and passed the three sip test with flying colors. Then tried the St. Andrews and while it tasted better than ever the DD became my favorite.
On returning to the U.S. I was astonished that my favorite hamburger place, which had an extensive bottled beer selection, had DD on the list. I ordered one but sadly was told they could no longer get it. Imagine the disappointment. Found the best beer I ever had and only got one.
I'm just about old enough ( I'm 60 now) to remember these past keg beers. Always remember the locals in Staffordshire pubs saying Watneys Red is dead, essentially that is keg beer all over. Also, the awful Whitbread Trophy Bitter advertising on Granada TV in the 80s. You cannot beat traditionally brewed ales, of which, thankfully, we have a plethora of locally.
