Terms of Service
Effective Date: May 23, 2026.
You are reading espressotechguide.com. We analyze espresso hardware. We measure temperature stability, burr alignment, and pump pressure. We publish our findings. By using this site, you agree to the rules below. If you do not agree, close the tab.
Acceptance of Terms
Operating high-end espresso equipment requires precision. Navigating this site requires basic agreement to our operational guidelines. When you read our teardowns, comment on our grinder reviews, or follow our maintenance schedules, you accept these terms. We treat our readers like adults. We expect you to act like one.
Intellectual Property and Copyright
We do the work. We buy the machines. We test the grinders. We publish the data.
Every photograph of a scaled-up boiler, every paragraph detailing PID offset adjustments, and every custom maintenance schedule belongs to us. You cannot scrape our content. You cannot copy our burr alignment guides and post them on your own forum. We spend weeks dialing in new equipment to find the exact friction points in daily use. That effort produces original, copyrighted material.
If you want to reference our data, link back to the original article. Quote a sentence or two. Do not steal the signal and pass it off as your own noise. We actively monitor for content theft and issue takedown notices without hesitation.
Disclaimer of Warranties and Hardware Risk
Espresso machines are dangerous. They combine 220V electricity, pressurized steam, and boiling water.
The information on this site serves as objective hardware analysis. It is not professional repair advice. We document how we clean our gear, prevent scale buildup, and modify our own equipment. We explain the exact concentration of citric acid we use for descaling. We show you how we lubricate the cam on an E61 group head. We do not guarantee these methods will work perfectly for your specific setup.
You assume all risk.
If you open your dual boiler machine, you void your warranty. If you adjust your over-pressure valve and blow a gasket, that rests entirely on your shoulders. We write about our experiences with specific tools like WDT distributors, blind shakers, and precision baskets. We do not promise that buying them will magically fix poor puck prep. Your extraction is your responsibility.
We test gear under specific conditions. Your home kitchen is not our test bench. Variables change. Water chemistry differs. Local voltage fluctuates. We hold no liability for the blind spots you encounter in your daily brewing routine.
Limitation of Liability
Hardware fails. Pumps die. Heating elements burn out.
Under no circumstances will espressotechguide.com or its operators be held liable for direct, indirect, or incidental damages resulting from your use of our content. If you run your flat burr grinder for three minutes straight, overheat the motor, and ruin a $500 piece of equipment, you cannot blame our grind size guide. If you strip a brass fitting while trying to install a flow control device based on our teardown photos, the replacement cost is yours to bear.
We provide high-resolution data on how machines perform. We tell you exactly what broke during our testing phase. We are not responsible for what breaks during yours.
Affiliate Disclosure and Financial Transparency
Testing espresso tech requires serious capital. We purchase commercial grinders, prosumer machines, and specialized testing equipment like Scace thermofilters.
To fund this operation, we participate in affiliate marketing programs. When you click a link on our site and purchase a bottomless portafilter or a new set of SSP burrs, we earn a small commission. This costs you nothing extra. It keeps the lights on and the espresso flowing.
This financial model never dictates our hardware analysis.
If a highly anticipated $3,000 machine has a terrible steam wand design, we say exactly that. If a popular grinder retains three grams of coffee per dose, we publish the exact measurements. We reject sponsorship deals that require positive coverage. We prioritize the signal over the payout. Our loyalty remains with the home barista trying to engineer a better shot.
User Conduct and Community Standards
We host comments to foster technical discussion. We expect a baseline level of competence and respect.
Do not post spam. Do not promote your own coffee gear store in our comment sections. Do not attack other users because they prefer conical burrs over flat burrs. The espresso community already has enough toxic gatekeeping. We will not host it here.
We delete noise. We ban users who clutter the discussion with irrelevant links or aggressive behavior. Keep the conversation focused on the hardware, the extraction, and the data. If you have a legitimate disagreement with our testing methodology, state your case with numbers and facts. We respect data. We ignore tantrums.
External Links and Third-Party Sites
We frequently link to manufacturer manuals, parts diagrams, and external retailers. We do not control those websites.
A link to a replacement vibratory pump on a third-party vendor site does not constitute an endorsement of their entire business. If you buy a part from them and it arrives broken, you must resolve that dispute with the vendor. We only illuminate the path. You walk it.
Governing Law
These terms operate under the laws of the State of Washington. Any legal disputes arising from your use of this site will be handled in its courts. We prefer to spend our time dialing in espresso, not talking to lawyers. Please use common sense before escalating a disagreement over a coffee machine.
Changes to These Terms
The espresso industry evolves. New pump technologies emerge. Our testing methodologies adapt.
We update these terms when our operational reality shifts. We do not send out mass emails for minor typographical fixes. We will update the effective date at the top of this page when we make structural changes. It is your responsibility to review this page periodically.
If you have questions about these terms, check our contact page. We answer emails between testing sessions. Expect a reply within 48 hours.
