About this guide

What this site is

The Home Coffee Bench is a reference for people who want clearer control over coffee prepared at home. It describes how dose, water, grind and brewing method interact, using measured terms instead of vague directions. The writing is intended to help readers understand a result and identify which variable may have influenced it.

Articles may cover brewing strength, extraction yield, ratio, water temperature and water chemistry. Espresso is treated through its measurable parameters, while caffeine and decaffeination are discussed as subjects of measurement and process. Storage and degassing guidance addresses how coffee changes after roasting without turning the site into a product catalogue.

How the content is built

Each numerical statement is checked against a named public reference before it is published. The subject determines the reference family used: brewing and water standards for brewed coffee, parameter references for espresso, food-science material for caffeine, and guidance on storage and degassing for post-roast handling.

The page design keeps a distinction between a measured parameter and a practical suggestion. A figure is presented with its context, while technique descriptions explain what to observe at home. This approach supports comparison without implying that every coffee, grinder, water supply or method produces the same result.

• Brewing strength, extraction yield, ratio, temperature and water chemistry
• Espresso dose, yield, temperature, pressure and shot time
• Caffeine amounts and decaffeination routes
• Degassing windows, rest guidance and storage conditions

What we do not do

The site does not promise a perfect cup or present one recipe as the answer for every coffee. It does not replace observation with fixed language. Grind, water and method can change the result, so the guide describes relationships and measurements rather than making universal claims about taste.

No medical or dietary advice is provided. Caffeine information is limited to measured amounts and the processes used to remove caffeine. The guide also avoids product rankings, purchasing direction and personal endorsements, keeping attention on technique, evidence and clear interpretation of brewing variables.

Independence

jdrcr.com is independent and non-commercial. It has no relationship with any roaster, equipment maker, cafe, coffee chain, importer, retailer or service company. No outside coffee business determines the subjects covered, the language used or the figures selected for explanation.

The publication does not sell products, carry advertising or maintain user accounts. Its purpose is informational: to make home brewing measurements easier to understand without presenting commercial placements, product endorsements or business-led recommendations as part of the guide.

Corrections

Accuracy depends on careful checking, but published information can still require clarification. A correction may address a numerical error, an unclear explanation, a missing qualification or a mismatch between a statement and the reference used to check it. Changes are made to improve precision rather than to preserve an earlier wording.

Readers should treat the page as a maintained reference and look for the reviewed date when assessing its currency. Corrections concern the content itself, including figures and explanations. They do not turn the site into a forum, account-based service or channel for individual brewing support.
