How roast level, roast date, method, grind and ratio shape a cup, and how to tell over-extraction from under-extraction before blaming the beans.
A household reads a bag of coffee by two printed facts first: the roast level and the roast date. Those two facts set the range of flavors the beans can give, and the brew method, grind and ratio then decide where inside that range the cup lands. Bitterness and sourness are usually extraction problems, not bean problems, and they can be corrected on the next brew.
Roast level describes how far the roaster took the beans, and it changes both what you taste and how easily the coffee gives up its flavor. A light roast is stopped earlier in the process: it keeps more of the bean’s own character, often read as fruit, floral notes or acidity, and it is denser, so it resists water a little more. A dark roast is taken further: sugars caramelize and oils come to the surface, so the cup leans toward cocoa, toasted notes and a heavier body, and the beans extract more quickly. A medium roast sits between the two and is the common starting point for a household that has not yet settled on a preference.
Look
Start with what is visible and repeatable. On this subject, that means naming the form, the joining points, the surface, the scale, and the condition before reaching for a historical label.
Know
The documented context comes next. Church documents, collection records, and conservation guidance answer different questions, so a confident sentence should make its source family clear.
Do not infer
A photograph or seller’s phrase cannot establish every material, edition, date, blessing, provenance, or devotional effect. Keep the open question visible and choose the next check.

When sources disagree or the record is incomplete, the uncertainty belongs in the sentence.
Care stop
Keeping a record so the next bag is easier
Stop before cleaning, polishing, washing, forcing, opening, or authenticating an object when its condition is fragile, its provenance matters, or the question belongs to a priest, publisher, seller, conservator, or other competent authority.
