One taster said the empty glass smelled like "burned plums on top of grandma's plum cake" — and that dried-plum nose is what everyone comes back to. This 1975 Port Mourant is intense, oily and dark: prunes, licorice, cola, leather and old wet oak. The palate turns drier and more bitter, like strong espresso, and several felt it runs thin for a 37-year-old at nearly 50%.
The community says- Intense dried-plum nose
- Rich, oily character
- Long espresso finish

Summarized by AI from community reviews.
Legendary prune-and-oak PM nose, drier palate A stunning old-Demerara nose of dried plums, licorice and oak that most agree the palate can't fully match — drier, more bitter and lighter-bodied than the aroma promises.

Update 10.02.2025 Stefan gave me the unique opportunity to taste the 74 Cadenhead PM, the 64 Cadenhead PM and the 75 Silver Seal PM at the same time - a thousand thanks for this opportunity! But what can I say about the rums? How can I do them justice and compare them fairly? I would probably have to devote entire evenings to each one. I thought they were all great. The Silver Seal, with its intense prune, had the most beautiful nose. In the mouth, it's a little thinner and not quite at the same level as the Cadenheads. I find it infinitely difficult to categorize the rums in a meaningful way. The last few sips were best when I was concentrating on the enjoyment and less on the analysis. The Cadenheads are both great - but also not a different world of rum compared to the 1986 Enmore or the 1975 Silver Seal. All insanely good. Unfortunately, I don't have the opportunity to differentiate substantially at this level. +1 Original 02/10/2024 This is a beautiful rum. I'm delighted to have had the chance to try it - thank you very much, Stefan! The profile is Port Mourant per excellence. I have the Karaya in my glass at the same time - the similarities are amazing. Despite the difference in age, Silver Seal is much more intense, while the differences in the profile are mainly characterized by the caramel.

01.02.2025 retasting at the Nordlichtertreffen and still great --------------------- 09.02.2024 Nordlichter treffen. Retasting and I stick to my initial score. --------------------- Opening this one also bacame a masterpiece of work as the Cork broke. Fortunately Stefan didn't give up and after a trip to a decanter and then back through a sift into the bottle, we tried to sniff the decanter and it was out of this world. We tried ti sniff the decanter the next day and it was like putting your nose into a freshly opened bag of prunes. ------------------ Had a nice evening with good friends and a bunch of Silver Seals, some with very nice age to them. This one is very nicely balanced once rested for a while. Woody with dried fruit and spices. I like the light leather, caramel and marzipan on the oily palate. Here I'd say oldies and goodies 😊
Review by DomM
Very nice and richt bottling indeed. Needs quite some pacience to open up, but after some the you are rewarded with a complex nose sporting dark and woody notes alongside some herbs. On the palate the PM is surprisingly approachable with surprisingly little bitterness, which only comes to play at the very end of the finish. Otherwise a brilliant combination of dark, roasted notes anlingside dried fruits and herbal notes which create a very complex array of aromas. Cheers to Stefan for the sample!
Review by w00tAN
The smell is so great, fruit bread is the first thing I think of. The color in the glass, divine! In the mouth, such a beautiful blend of fruit and spice, you discover new facets with every sip. The alcohol is perfectly integrated. Anyone who likes good heavy rum will fall in love with this. Thanks to Stefan for the opportunity to try it, really not easy to get. Had the chance again
Review by zabo
Franconian Tasting Gang First of all, a big thank you to MoparRules up north. Let the impressions settle calmly once again. I expected woodiness and bitterness here. But that's not the case at all. What a positive surprise. Simply a very noble drop that few will probably have in their glass in their lifetime. You really have to be grateful for that. It's a challenge to somewhat balance that at MoparRules.
Review by Christoph H.
One impression is simply confirmed time and time again. Both this and the other PM 75 version from Silver Seal are among the best old school PM noses I know. Without ifs and buts! The smell is incredibly intense, very, very round and simply has everything you would expect from a 75 PM. I particularly notice the sweet, dark fruitiness and tropical fruitiness. A really catching combination of raisins, prunes, passion fruit and passion fruit. The characteristic old, wet and musty wood is also fully present and is on a par with the fruitiness. It continues with lots of dark notes such as treacle, caramel, cola and Ricola herbs. Unfortunately, both Silver Seals have the same weakness: the palate can't quite deliver what the nose promises. Other 75s can do this somewhat better. Even though the rum is still almost 50%, it really seems extremely thin. Sweetness is only perceptible at a medium level, if at all, and the bitterness really hits the longer it is in the mouth. At the beginning there are still clear dried fruits, but these are then covered by herbal and roasted notes. In my memory, the other version is definitely a little better in the mouth. It should have come out of the barrel a little earlier. Overall, I like younger old school PMs with more ABV a little better. The absolute crowning glory here is clearly the Uitvlugt 75 from Cadenheads with over 70% However, this should not obscure the fact that this is still an excellent rum and a liquid story, which undoubtedly satisfies the old PM craving profile
Review by Jarek
What a nose! Prunes, lots of spice, cola, Maggi, licorice. I agree with Serge that it reminds me of a good REV. If there was a perfume with these notes, I would buy it. Wood on the palate, of course, but just right. Because of the color and the age, I expected wood without end. Enough power, even if ABV suggested less. Thanks to Stefan for the donation to FRTG. This gives you a place in my hall of fame of rum friends 😁
Review by Serge
When you open the sample, you are immediately greeted by the most intense scent of moist prunes. Wonderfully fruity and not at all what you would expect from "younger" PMs. The closest asossation might be a 94 REV. Let it rest for now. After a good hour, great notes of licorice, spices and cola (good cola) with orange oils. In addition, beautiful wood, leather and a wonderfully dark and dense character. A dream. Much less bitter on the palate than expected. Beautifully dry. Black tea, earth, cocoa and plum jam join the elements of the nose. Wonderful. A new aspect with every sip. Many (many) thanks Stefan for this very generous sample donation to the Franconian Tasting Gang. ❤️
Review by Mopar Rules
Childhood memories! My grandma cooking plum jam on her old, wood fired oven. What an intense and heavy rum on the nose. The dried plums are so present snd dominant, amazing. Different on the palate with a strong bitterness like a strong espresso. Not for cappuccino drinkers and sedan drivers. Burned caramel, oak, espresso, spicy. An imense density. Not as complex as the recently tasted Diamonds Velier 1996 and 1999 but even heavier and richer, more oily. Endless finish of espresso and oak. The empty glas has s mind blowing smell like the burned plums on top of grandma’s plum cake. Love it.
Review by F.L.O.
You don't get to enjoy such an exceptionally old rum every day. Licorice, slight bitterness, wood and dried fruits take turns. Nice and dry in taste and the bitterness fades very quickly. Then comes a sadly not so long finish with plenty of licorice. Nice piece. Thanks Stefan! Tried again today, still awesome. Slightly adjusted due to the not so long finish.
Review by Schnubbii
Nose: All the dried fruits in the world. Palate: A beautiful harmony of dried fruits, grape notes and burnt caramel. Slightly bitter and very slightly some mint in the background, some black tea. A truly great Port Mourant! Edit: Simply awesome. Brutally harmonious, with lots of dried plum, nuttiness and a bit of pencil.
Review by HenryL
Many thanks Stefan for the opportunity to try this excellent rum. Exciting comparison with the Karaya, Port Mourant is clearly recognizable. You can tell the extra years, but it handles it. It doesn’t get too woody but simply more mature and elegant. All that with a good portion of dried fruits.
Review by Maxence
Finally able to try this legendary release from Silver Seal ! The least we can say is that this rum does not disappoint. Nose is perfectly balanced but the palate unfortunately lacks a bit of sweet notes compared to the latter. The finish is super long with a nice hint of floral notes. An outstanding representative of dark Port Mourant rums which totally deserve its legend 😋
Review by Buddudharma
A privilege to be able to taste this rum. Surprisingly little bitterness and a really great, complex profile. Many thanks to Stefan and the Nordlichter crew!
Review by Filip Šikula
Dense oily profile of port mourant. Intense aroma full of dried fruit, tobacco, leather with black tea. The taste is full and very complex. Lots of chocolate, fruit, tobacco and leather tones. A very exceptional experience.
Review by Pavel Spacek
Extra wooden and learher Port mourant. Round, warm, prunes a little bit.
