One of the most common questions about serving port wine is whether it needs to be decanted before serving. The short answer is it depends on the style. Some ports must always be decanted, others never need it, and a few fall somewhere in between. This guide explains exactly which port styles need decanting and why, so you can serve every bottle correctly and with confidence.
For the full step by step decanting process once you have confirmed your bottle needs decanting, see our guide to decanting vintage port.
Why Do Some Ports Need Decanting?
Port wine that ages in the bottle, primarily vintage port and crusted port, gradually throws a natural sediment as colour pigments, tannins and tartrate crystals precipitate out of the wine over years and decades. This sediment is entirely natural and harmless but unpleasant to drink, and needs to be separated from the clear wine before serving.
Port styles that age in oak barrels rather than in the bottle, tawny, colheita and most LBV, have already undergone controlled oxidation during production and do not throw sediment. These can be poured directly from the bottle.
Vintage Port, Always Decant
Vintage port must always be decanted. It is bottled unfiltered after around 18 months in cask and designed to age for decades in the bottle, during which time it throws a heavy sediment. Stand the bottle upright for 24 hours before opening to allow the sediment to settle, then decant slowly against a light source, stopping when you see the sediment approaching the neck.
Young vintage port (under 15 years) also benefits from two to three hours in the decanter before serving to allow it to open up. Older vintage port should be decanted no more than one hour before serving as it can fade quickly with extended air exposure.
Crusted Port, Always Decant
Crusted port is an unfiltered blend of multiple vintages that ages in the bottle in the same way as vintage port, throwing a heavy sediment. It must always be decanted before serving. Stand upright for 24 hours, decant slowly and stop when sediment approaches the neck. Treat it exactly as you would vintage port for decanting purposes.
LBV Port, Depends On The Style
Late Bottled Vintage port comes in two forms and the decanting requirement differs between them.
Filtered LBV is the most common style, aged four to six years in cask and then filtered before bottling. No decanting needed. Pour directly from the bottle.
Unfiltered LBV is aged for longer and bottled without filtering, allowing it to continue developing in bottle. This style may throw a light sediment and benefits from decanting one to two hours before serving. Unfiltered LBV is generally labelled as such. Look for "unfiltered" or "traditional" on the label.
Ruby Port, No Decanting Needed
Ruby port is a filtered, blended style designed for immediate drinking. There is no sediment and no benefit to decanting. Open the bottle and pour directly. Ruby port is served at slightly below room temperature with no preparation needed beyond a brief 15 minutes in the fridge if your room is warm.
Tawny Port, No Decanting Needed
Tawny port is aged in small oak barrels where controlled oxidation gradually develops its characteristic amber colour, nutty complexity and dried fruit character. Because the ageing happens in barrel rather than bottle, tawny does not throw sediment and no decanting is needed. Pour directly from the bottle and serve lightly chilled at 12 to 14 degrees.
Colheita Port, No Decanting Needed
Colheita port is a single harvest tawny aged in barrel for a minimum of seven years before bottling. Like tawny port, it ages entirely in cask and does not throw sediment. Pour directly from the bottle and serve lightly chilled. Colheita is ready to drink immediately on purchase with no preparation needed.
White Port, No Decanting Needed
White port is made from white grape varieties and does not throw sediment. No decanting needed. Serve well chilled at 6 to 10 degrees, either neat or as a white port and tonic with ice, a slice of lemon and a sprig of mint.
