the Dual Boiler™

The machine for the home barista chasing perfection.

  • Espresso perfection requires precision temperature and pressure control, consistently, every time, and the Sage by Heston Blumenthal Dual Boiler™ espresso coffee machine will deliver just that. It features dedicated stainless steel boilers for steam and espresso, allowing simultaneous milk texturing and extraction consistently at 93⁰C.

  • The Dual Boiler features an Over Pressure Valve. This commercial feature limits the maximum pressure throughout the extraction, preventing bitter flavours in the shot.

  •  It also offers a true low pressure pre-infusion, which gradually increases the pressure to gently expand the grinds for an even extraction, for a smoother taste.

  • The brew temperature, pre-infusion pressure and duration are all programmable.

  • The Dual Boiler™ comes with our ‘white glove service’ – your very own personal coffee technician, who will set it up, teach you how to use it and enjoy a cup of coffee with you afterwards.

Once you get the Dual Boiler home, call us and we will send a trained coffee engineer to your home to ensure your machine is set up for optimal performance.  Offer is free and available to all consumer on mainland Great Britain. click here for details

"I've now had the Sage dual boiler for almost year and I'm absolutely delighted with it. I'm a huge coffee fan and with this I'm consistently producing coffee that certainly rivals that of the major coffee chains and at times comes close to emulating the great coffee from my local specialist (read 'hipster') coffee shop - and they are huge coffee nerds.

I've paired this with the Sage grinder - with which I'm not quite so happy - there's not quite the level of micro-adjustment on the grind that really enables you to fine tune the recipe, and it's not as consistent as I'd like with the dosing - but then, I'm quite a perfectionist.

I've recently had a days barista training at the marvellous Prufrocks in London, and they were very complimentary about the machine as a home espresso maker. Following this, a little fine-tuning to the coffee recipe and a great improvement to the latte art, and I'm producing some stunning flat whites. (For those of you who are interested - generally looking at around 16.5g of coffee in the basket for a 34g extraction over around 30 seconds.) Being able to change between time and volume for extraction on the machine is amazing - it's really made a difference in consistency.

I wouldn't agree with one of the below comments, where they mention using cheaper coffee - if anything this machine will encourage you to experiment with all kinds of freshly roasted specialist coffee, as it's possible to distinguish much more difference in the espresso produced and highlight more subtle flavours. Freshly roasted beans (less than 2 weeks since roast) are the ideal.

It's worth spending time on the cleaning cycle / flush / descale - you've got to look after this as a specialist machine, but the rewards are well worth it."

Sage Duel Boiler

"Having been a Coffee "nut" for over 30yrs and owner of Bean to Cup Gagia and De Longhi Expresso makers, also a La Pavoni Piccolo. I also Roast green. Beans on occasions. However, I have yet to produce an anywhere decent Expresso from my Sage.

Textured Milk is superb - could not ask for better.

The White Glove Service (Coffee Classics Ltd, Nick) arrived promptly and also failed to produce an Expresso! Nick stated that the Beans were not suitable. I had expected the White Glove Service to furnish Beans that they knew were suitable for setting-up the Machine. This was not the case. I have since tried Beans recommended by White Glove Service, but to no avail.

Very disappointed with the situation because this Machine is very adjustable for Varying Brew requirements. (One of the reasons I chose it) The magnificent Sage Pro Grinder performs well.
A very good looking Machine, accessories and cleaning products seem over expensive.

I am hopeful that eventually I shall be able to produce an Expresso!"

Kitchen Porn that actually works (extremely well)

"Having caught the coffee bug a few years back I have gone through a few machines pod and bean to cup but as my interest grew I needed a proper espresso machine. What I did know was that my frustration with all the machines I had was the time it took to make an espresso and then steam some milk it took so long and was very frustrating.

Being a geek at heart I researched my next machine and didn't make the decision lightly after 6 months I made the decision to go for the dual boiler as it had everything I wanted and also fitted in the only space I had available in my kitchen.

When it turned up even my wife was impressed and she doesn't like coffee it looks so sexy and feels solid, setup was very easy and had it up and running within 10 minutes.

I did have some frustrations initially with the espresso but this is to be expected as it is a skill but after some practice and the white glove service I know have them nailed and with different beans as well.

From the start the milk was so simple all the machines I had before just didn't steam milk easily or well and being able to steam at the same time as making the shot is life changing and the kids and the wife both love their hot chocolates and baby chinos.

I am so pleased with the dual boiler, I did say that if I got it I wouldn't spend money on coffee at work during the day but deep down this was only to make the wife agree to the purchase but I can honestly say since I've had it I haven't purchased one coffee as I think that I can do a flat white as good as if not better than a lot of the artisan coffee shops in east London where I work.

Don't hesitate this is a great machine in both looks and function and I have Zero complaints and look forward to many years of happy mornings and late nights."

Proper coffee

"After years of using expensive capsules and not getting a perfect coffee I finally decided to invest in a decent espresso machine.

The coffee is consistently excellent but the main joy is being able to prepare milk suitable for either latte or cappuccino, this takes a bit of getting used to but after an excellent tutorial from Sage's White Glove Service I have finally got the hang of it.

Paired with the Sage Smart Grinder it takes no longer to make a decent Italian style drink with the bonus of much cheaper coffee.

A great investment."

Incredible Coffee Machine...so much better than the well known coffee shops!

"My husband and I have wanted this machine since we first saw it being demonstrated in the Oxford Street branch of John Lewis. We finally decided to buy the Dual Boiler as an early Christmas present to ourselves. It is amazing, the coffee tastes so much better than anything else we have tasted. We have had 3 Nespresso machines, 2 Tassimo machines and a Gaggia machine before but none of them come close to this one in terms of the coffee taste. We always used to have sugar or honey in our coffee but no longer need it because the Dual Boiler is designed to ensure you never get a bitter tasting cup of coffee. I would not hesitate in recommending this machine, it heats up very quickly and is incredibly easy to keep clean. As part of the deal you also have the 'white glove service', I just called Sage and they arranged for someone to come out and show you how to use the machine and how to get the most out of it."

Love at first brew

"After years of struggling with smaller machines - albeit very good brands - as in 3 different espresso/cappuccino machines - we finally decided enough was enough and that we needed a decent machine that was consistent. We did not want to go the capsule route and the automatic machines seem too soulless. We are careful about our choice of coffee, the temperature of our frothy milk, etc and make our coffee with loving care in pre-heated cups. The Double Boiler therefore gives us the technical superiority without losing the mystic of coffee making.

Research also suggested a double boiler was ideal and the short warm up time of the Sage Double Boiler sealed the deal. As we make between 3 to 6 cappuccinos a day, it seemed a sensible investment.

The instructions are well written and it is simplicity itself to use and clean. I don't know how we did without it all these years."
