Poured neat, this is a slow, contemplative Port Mourant: heaps of prune on the nose, then chocolate, old leather, oak and molasses on the palate. The 37 years show as a deep, full body with just a touch of sweetness and a bitter edge some love and some find a bit much. One taster called the finish one that "snap never ends," with the alcohol almost invisible.
The community says- Deep prune & leather
- Long, evolving finish
- Alcohol well integrated

The look inside the bottle
How does Silver Seal Port Mourant Demerara 1975 taste?
Summarized by AI from community reviews.
Deep, woody old Port Mourant with prune and bitter edge Members rate it very highly — complex plum, wood and leather with a near-endless finish. A few find it tips slightly bitter from all that age; one wished the taste lingered longer.

Review by Leo Krüper
Inspiring rum. Bottled at just the right time before it turns bitter. Tastes like a 94 REV only better. Great woody notes, eternal finish. Comprehensive creaminess and even a slight sweetness despite its great age. Wow!
Review by Johannes Eisner
A full load of plum on the nose, then a little more bitter on the finish than other PM 7x.
Review by Kevin Sorensen 🇩🇰
This is a great sip of a very rare bottle made on the oldest still in the world. Very expensive golden drops but well worth it.
Review by zabo
Thanks to DomM for the birthday sample. After I could also sponsor the 75er PM from Velier, it was a comparison on a very high level, probably only about subjective nuances. After I had the Cadenhead 64 in the glass before, I couldn't really find any big differences. All super delicious, complex drops of the gods.
Review by Adrianv
Very unique and strong staff. Bit too matured and bitter for me but complex and extravagand. I like it very much!
Review by Filip Šikula
One day, and it won't be long, we'll only be able to remember rums like this. Beautiful, complex nose. But the taste. Chocolate, bark, wood and plums. A finish that seems endless and alcohol? As if it wasn't there.
Review by Pavel Spacek
Amazing old wood, leather and brown fruit. Full body, integrated alcohol. Unfortunately the taste least in mouth just for about 5 mins. Parametr for improvement :)
Review by Martin Švojgr
So this is heaven in the mouth. Even the dark mahogany color hints at what you're going to drink. Tons of dried plums, wood, very dark chocolate and yet softness, fullness and a very long tannin finish. Really awesome!
