Worked example: separate season from storage
Apply the mechanism to a concrete comparison.
The argument
What this chapter will give you
Trace a glass backward through season, site, farming response, harvest, grape condition, selection, and bottle development.
This is a reading chapter, not a definition enlarged to fill a screen. Its sections build the idea from mechanism and method to the language you can use in front of an actual glass.
Worked example: separate season from storage
Imagine two bottles from the same producer and harvest year. One was stored cool and consistently; the other experienced substantial heat. Differences now cannot automatically be assigned to vintage weather because the growing season was shared and storage was not. Conversely, comparing two harvest years today also compares different bottle ages. Start with records of the season, harvest and winemaking, then ask about storage and bottle condition. An amber colour or tawny rim may support development, but neither supplies an exact calendar date or proves why that development happened.
Rim variation is a clue, not a clock
A mature red often shows a wider, paler, more orange-brown rim because pigment chemistry and precipitation change over time. Variety, pH, extraction, oxygen, storage, and glass shape complicate the clue, so rim variation cannot establish an exact vintage by itself.
Bring it back to the glass
Three checks before the conclusion
- Name the process or growth stage before explaining its consequence.
- Use the worked example to distinguish an observation from its possible cause.
- Identify the missing evidence before applying the explanation to a real bottle.
The language bench
Solid things you can actually say
Use these as sentence shapes, not answers to copy. Replace the details with what your glass can defend.
Start here: vintage means harvest year, not current age
- “Vintage is the year the grapes were harvested.”
Worked example: separate season from storage
- “Imagine two bottles from the same producer and harvest year.”
What can the explanation support?
- “Vintage reasoning separates direct observation, documented events, plausible pathways, alternatives, and confidence.”
Make the sentence earn its keep
“That one clue proves the whole story.”
“Vintage reasoning separates direct observation, documented events, plausible pathways, alternatives, and confidence.”
Keep the mechanism specific and match confidence to the available evidence.

A five-minute field exercise
- A mature-looking rim proves a hot vintage: what is missing?
- Write your answer and its reason before reading the explanation.
- Answer: Evidence connecting that harvest season to this wine. Variety, extraction, pH, age and oxygen exposure can also alter colour. Write separate columns for seasonal conditions, grower response, harvest condition, cellar choices and bottle development. Put unknowns in the relevant column.
