Understanding Port maturation: Distinguishing perspectives for Vintage, LBV, and Colheita
Read geography, grape resources, and production processes separately.
Vintage
Early bottling, changes in bottle thereafter
LBV
Check for later bottling and whether filtration was used
Colheita
Single vintage, long maturation in wood.

FIELD NOTE 01
Even in a single vintage, the process differs.
Vintage, LBV, and Colheita are all categories derived from a single harvest year, but their aging and bottling processes differ. Vintage is bottled relatively early, and changes in the bottle afterward become a major distinguishing point. LBV is bottled later than Vintage.
Colheita spends extended aging in wooden casks. Do not group the three just by their vintage years; it’s easier to explain differences if you separately look at time and vessels used before bottling.
FIELD NOTE 02
Information to confirm for LBV
There are both filtered and unfiltered LBV wines. Unfiltered examples can change in the bottle and develop sediment. Do not assume all LBVs will mature the same way in bottle just from the name.
Check for indications like 'Unfiltered' and bottling year on the label or producer material. When considering how to handle a bottle before opening, it helps to make a habit of returning to information about the specific wine itself rather than just the category.
FIELD NOTE 03
The indicated number of years is not the harvest year
Ports with an age indication are a blend of wines aged in wooden containers, and are balanced for the characteristics corresponding to the stated number of years. It is incorrect to read “20 years” as meaning a wine from a single harvest left for exactly 20 years.
When comparing year indication with a Colheita harvest year, do not combine numbers of different meanings in the same field. Record “harvest year”, “years of maturation indication”, and “bottling year” separately.
FIELD NOTE 04
Distinguish the time spent in wood and in bottle.
Draw your own diagram with time on the horizontal axis, and mark the point of bottling. Highlighting the period after bottling for Vintage, and the long time in wooden vessels for Colheita, shows that even from the same old harvest year, the route can differ.
Rather than simply ranking longer aged wines as better or worse, connect the type of winemaking sought with the style. In the exercise, write one similarity between Vintage and Colheita and two differences before opening the explanation.
The common point is that they come from a single harvest year. The difference lies in the time until bottling, and whether the maturation vessel is considered mainly bottle or wood.
