Recipe: Theakston Old Peculier (version 1)

Theakston Old PeculierFull recipe and process can be found online here.

So begins our journey looking into some classic British Browns and Olds.  First up, probably my favorite commercial Old Ale, Theakston Old Peculier from Masham in Yorkshire, England.

There is something really satisfying for the homebrewer when brewing an Old Ale recipe.  Unlike the English Pale Ales we have just finished, which tend to more delicate and one mistake in any ingredient is heavily punished, it is really hard to mess up an Old Ale.  What with the copious amounts of dark Jamaican sugar, Golden Syrup, Chocolate Malt and Molasses to compliment the mainstay Pale Malts and English Crystal. You end up with a rich, smooth almost rum like dark ale that will last forever in the cellar if we ever gave it a chance.  So I must say I had a ton of fun with the Theakston recipe and have taken more than a few risks in the quest to faithfully recreate this quintessential Yorkshire Old Ale.

The family owned Theakston Brewery is located in the North of England in Masham, North Yorkshire. A town steeped in brewing history dating back to before William the Conqueror.  The village of Theakston, and the namesake of the family was referenced in the Doomsday Book, created in 1089, and the Theakston coat of arms created in 1587 for Sir Richard Theakston whose descendent, Robert, in 1827 went on to create the first Theakston brewery in a pub called the Black Bull.  In 1875 Roberts son Thomas takes over the brewery building a new one in the process, which is still used today.  The company proceeded to grow buying many local breweries to meet growing demand.  In 1984 the Theakston family joins the wave of independents selling to larger firms and finally decided to sell and the brewing of its flagship products moves away from historical Masham to larger capacity breweries of the acquirer. Now proceeds a story we have become familiar with, bigger company x sells to even bigger company y (in this case Matthew Brown PLC is bought by then North East England brewing giant Scottish and Newcastle, maker of Newcastle Brown, who in turn is taken over by Heineken in 2008).  In 2004, as some previously Theakston owned breweries are closed and brewing operations moved as far north as Newcastle, four Theakston brothers buy back the company, making it an independent family owned brewery and in 2009 announced that brewing would again return to Masham after 35 years, bringing the story full circle.

On to the ale itself.  According the The Real Ale Almanac this is the flavour profile we are trying to recreate:

Dark and vinous old ale bursting with complex fruit flavours. Massive winey bouquet of rich fruit with peppery hop notes.  Toffee and roast malt in the mouth, deep bitter-sweet finish with delicate hops

On to the ingredients.  The brewery website was actually very unforthcoming with ingredients.  All they have posted is the use of Fuggles hops and a ABV of 5.6%. Its a start. The Real Ale Almanac was a little more helpful listing pale malt, crystal, unmalted cereal (torrified wheat) and sugars.  Fuggles and “other” hops, with an IBU of 29, 48 24 SRM colour, and an OG of 1058.

This has to be the toughest challenge we have had yet. Typically by this point we have a complete list of hops and malts  and enough variables in colour, gravity and bitterness to fire up the calculator and get to work.  Instead we have incomplete hop information and no FG.  What is most concerning is the vagueness around “sugars”. In English Pale classification ales sugar is used to bolster ABV with no flavour so its safe to assume cane sugar.  With Old Ales all types of sryups and dark sugars are used, imparting dark rum like richness to the finished brew.  This is going to be tough (but fun).

So time to consult the BJCP classification to see if we can gain any insights into the types of Crystal Malt and sugars used.  Old Ales are listed under the classification of Strong Ales.  Here we see Caramel Crystal Malts, and a sparing use of both Chocolate and Black Malts which is to be expected given the rich dark colour but not too much or risk imparting too much of the roasted smokey flavour. This ale is all richness and fruit.  It is the following sentence in the BJCP guidelines that could help answer our question:

Adjuncts (such as molasses, treacle, invert sugar or dark sugar) are often used, as are starchy adjuncts (maize, flaked barley, wheat) and malt extracts

This helps greatly.  So I then took to the internets and enquired into the sugar mix employed by other homebrewers attempting to recreate this historic ale.  To my surprise I found consistency, the use of Golden Syrup, Molasses and Dark Sugar.  The quantities varied but this should be enough to get us started.

The big question for me remains the yeast. We know we need fruit but at the same time we need a yeast that attenuates fairly well to get from a OG of 1058 to a final ABV of 5.6% (implied FG of approc 75%). It cannot be a dry finishing yeast because of the strong fruit flavours in the tasting notes.  I scoured the yeast strains available to homebrewers and scratched my head.  There are limited Yorkshire yeasts and I could find little to provide the level of fruit and attenuation implied by the data.  Finally I got some inspiration from the Pretty Things Old Ale, inspired by Theakston Old Pecuilier among others, and their use of German and Belgian strains.  So I started digging and hit pay dirt with various Belgian strains. You can have your cake and eat it to providing high attenuation and fruit flavour characteristics.

This just leaves the hops. Not so worried here, as the BJCP guidelines for Old Ale state:

Hop variety is not as important, as the relative balance and aging process negate much of the varietal character

So I am going to stick with Fuggles which will definitely provide the peppery hop notes, and we know the target IBU is 29. The calculator can do the rest.

Next stop is to input the ingredients into the beer calculus system on and balance the quantities in order to create a workable recipe conforming as best we can to the constraints above.

    Did you use anything special for priming the bottles?  I’ve always heard the rumor that Theakstons uses treakle for their live barrels.

  • Stephen C Jenvey

    I did, used black treacle from my local British food supplier. 3/4 cup for five gallons. Boiled it in 1pint of water and added to the priming bucket. Enjoy

  • droy

    I think it should be 48 EBC not SRM.  That beer is a deep brown with ruby highlights which you wont get at 48 SRM.  Aim for 24-25 SRM.  My $0.02

  • Stephen C Jenvey

    Thanks so much for the feedback. I definitely misread the almanac, it is written for a British audience hence the mistake.

  • Bniermeyer

    I followed the recipe exactly, accept adding a little too much molasses by mistake (extra 2 oz.).  The OG was 1038 which is too low.  Active fermentation lasted only a couple of days.  I pitched a yeast starter.  The krausen fell after 48 hours.  After 4 days the gravity measured 1008.  Did I do something wrong?  Any ideas?  I plan to go to a secondary after 1 week and let it sit for a month, then to a corny keg.

  • Stephen C Jenvey

    Did you make a 2.5G batch? The recipe was an small experiment batch. I do have a 5G also on Hopville which I created after I made the experimental batch
    Let me know. If we need to dig further we can.

    I just found this website and it makes me want to return to England.  My wife and I enjoy touring London; We rent an apartment and then spend the time seeing as much as we can.  Since we do a lot of walking we need to use the loo once in a while and her suggestion is that we stop in a pub and try a new beer.  I homebrew here in the states and make mostly ales.  My faviorites are British stouts, porters, old ales, milds, bitters and American IPAs.  I miss the pubs and thier great beers.

  • Stephen C Jenvey

    Thanks for posting. I miss the old country too, especially the pubs. The beer and atmosphere would be hard to recreate here. Its the reason I started homebrewing again and worked on some of my favorite beers. Cheers and happy brewing.

    Do you have or know of a link to a good all-grain recipe? Also, what’s the composition of Lyle’s Golden Syrup? I brew in Asia, so substitutions are a requirement. Cheers!

  • Stephen C Jenvey

    I do not have an all grain but I am sure you could replace the DME with some equivalent grain. Lyles Golden Syrup is a rich yellow molasses. You could replicate by making a brown sugar simple syrup.

  • TOP_Brewer

    Stephen, do you have a new link for your 5G recipe?

  • Stephen C Jenvey

    It looks like the the old recipe it gone, here is the new one.
