أسئلة شائعة عن علم المياه
What is the difference (if any) between a mineral salt, a dissolved mineral, and a mineral ion? A salt, in chemistry, refers to any ionic مركب (IUPAC, 1990). For example, table salt, sodium chloride, is an ionic مركب composed of sodium (Na+) and chloride (Cl-)...
Sometimes Geisha Seeds Don’t Look Like the Typical Geisha Shape
Geisha, or Gesha, is a highly prized variety, with a distinctive jasmine aroma, and bright fruity حموضة. These distinctive characteristics mean it has dominated coffee competitions, and become infamously expensive as a result. Geisha beans are often quite large and...
‘Seasoning’ Group Heads: Useful or Nonsense?
‘Seasoning’ of a group head refers to the practice of making one or more ‘sink shots’ after cleaning an espresso machine - that is, shots that are thrown away with no attempt to taste them. Advocates of seasoning claim that the first shots have an unpleasant metallic...
Why Do Coffee Grounds Stick to Tampers, Distribution Tools, and PuqPresses?
Coffee grounds are inherently slightly sticky. We rely on this fact during tamping to hold a القُرص together, and to create a good ‘seal’ between the edge of the القُرص and the basket. Unfortunately, this also means that coffee grinds can stick to tampers and tools, in...

Keep It Simple
Coffee brewers— both professional and enthusiast— love to make things complicated. Complex multi-step brew recipes and brewing devices with some unique feature have become standard. Fancy new features on espresso or brewing machines are demanded without any evidence of their necessity (hello pressure profiling).
Barista Hustle Community Guidelines
We aim to engage in meaningful, professional, friendly discussions surrounding coffee. A fundamental goal of Barista Hustle is to help the world make better coffee — and there is a lot that falls under that umbrella. So we want to talk about the deep and meaningful, the scientific and technical, the broader industry-wide topics, and the smaller individual level aspects. We want to talk about all the important stuff.
To enable these conversations to happen in a positive, respectful, and equitable manner, we have a few guidelines.
The Great Distribution Tool Debate
Two months ago I was embroiled in a twitter battle for three tweets about distribution tools. Note I didn’t say they don’t work. I just wanted (and still want) empirical evidence that they do. Please also note I’m not attacking any singular product; I was asking for evidence for *any* of the available distribution tools. The goal here is truth…
Coffee Is the Leased of Your Worries …
