The head brewer at Adnams said he was "really excited" about the launch of a new seasonal spring beer.
The Southwold-based brewery has teamed up with Berkshire firm Siren Craft Brew to create the tipple, called Secret Springs.
Dan Gooderham, Adnams' head brewer, said he was delighted with the result.
Mr Gooderham said: "We’ve known Siren over the years, and it is exciting to finally be able to work with them.
"They make exceptionally good beer, and we always try to collaborate with like-minded brewers.”
Adnams, based in Southwold, was launched in 1872 by two brothers, George and Ernest Adnams.
Mr Gooderham said he had known Siren's head brewer, Sean Knight, for some time and they were excited to finally get the chance to work together.
In an ocean of options, they steered towards New England and West Coast IPAs, eventually landing somewhere in between thanks to their final choice of hops.
Secret Springs is just 3.4pc and the spring pale ale gave the brewers the opportunity to play around with some punchy, newer US varieties.
The resulting brew is said to taste of mango and guava and has a sweet finish.

Mr Gooderham said: "Sean wanted to pitch this beer between a New England IPA and a West Coast IPA.
"The middle ground being something that sits between juicy, and strong bitterness.
"When brewing a beer at 3.4pc abv, a delicate balance must be struck with the hops and the malt. Alcohol has a lot of perceived sweetness.
"In stronger alcohol IPAs there is more room for hop flavour to balance the bitterness from the hops.
"Having a small amount of acidity on the taste perception threshold will help to give balance to the beer.
"I’m really excited to find out how our yeast and these hops interplay.”
Adnams brews its beer in Southwold and directly manages over 70 pubs across the region. The firm also supplies more than 1,000 other outlets with its beer.
