Beautiful aroma, tannins not obtrusive, seems to be entering prime drinking window

Taster #9786 · Jan 23, 2026
All black fruit and cedar shavings on opening. Bit of dirt in the finish. Exactly what I like from a just popped Margaux. Tannins are definitely there but unobtrusive. Seemed a bit thin on opening but blossoms after 20 minutes in the glass (Zalto Universal). Then the bacon fat, weightier middle palate, a brief flash of black pepper and graphite (just to remind you Margaux is next to Pauillac), and then a long saline-inflected glycerin finish comes out. Very perfumy …

Wow…10 years young this is certainly an enjoyable wine that I expect will only open with time…beautiful bouquet of black fruit to open with somewhat tight earthy tones to taste and velvety tannins ..medium finish but can feel the structure wanted to unfold…decanted for 2 hours..look forward to next bottle in a few years

Château Giscours Margaux GCC 2015 (14% ABV) 60% CS / 32% M / 5% CF / 3% PV The bottle was uncorked six hours before the meal on the first day and then left to stand at 15°C. Between the day before yesterday and yesterday, and also between yesterday and today, the wine was stored corked at approx. 14/15° in the unheated conservatory. When first uncorked (cork like that of a freshly bottled wine) and throughout the first evening, the …

I decanted for 6 hrs following the suggestion of recent notes (thx). It was smooth with a darker fruit profile, leather/tobacco and a med+ finish, by my tastes v good now and for another 3/5 yrs.

Slightly improved since our last note of Dec. 2024. I had intended to keep this for quite a few more years but we had the chance to share it with my son who gifted it to us. It is drinking beautifully and benefitted from being held for 6+ hours after de-corking. Given this time to breathe and develop before drinking, a touch of early austerity and acidity had softened. It was soft, smooth and complex with excellent fruit and balance. …

Inclined at 15° in the morning, opened at lunch time, decanted in the evening and back in the bottle for presentation, there was no sediment, bought the bottle en primeur. Beautiful Margaux. Ready to drink, lots of black fruit and a bit of cherry, tannins well integrated, forest and herbs, in particular thymn, rosemary, tiny bit of cloves, leather, graphite and white chocolate.

The 2015 iteration of Château Giscours is a blend of 70% Cabernet Sauvignon, 25% Merlot and 5% Petit Verdot, aged for 17 months in French oak barriques (50% new). Now at 10 years of age, it is still a youthful deep-to-opaque ruby in color. On the nose, it offers an intense bouquet of black currants, red bramble fruits, allspice, violets, tobacco, cinnamon, truffle and aged leather. Medium-to-full-bodied, freshly acidic, proportionately oaked and with well-integrated alcohol (13.5%), it delivers flavors mirroring …

Dark berries and a good dose of oak in the bouquet. Same on the palate, juicy acidity and tannin. Elegant wine.

The fruit and complexity is lovely, and this was enjoyable with a perfectly medium rare filet mignon. As I sipped on it on its own though, the back of the palate and aftertaste had way too much acidity for me, even after a 6-hour decant. Would be open to trying again in the future, but it needs more age and/or more aeration.

Taster #5752 · Oct 7, 2025
Dark red to rim. Cassis, red fruits, floral notes on the nose. Medium-full bodied, lots of up front ripe fruit, well balanced with good acidity and robust tannins, flavors follow the nose, no aged complexity at this point, medium finish. Pretty modern, would be hard to peg this blind as Margaux or even Bordeaux, but a very enjoyable drink. Will it turn into a classic Margaux with age? Time will tell. Happy to have more and plan to keep opening …

An astonishing rendition of Giscours. The interest thing about all of these Margaux is that they "lack" the chocolate / coffee / mocha thing on the nose - instead is just pure raspberry fruit with savory notes in the background. Probably the best Giscours I have ever had. Drinks well now but I would wait for two more years. This note taken after a 14 hour bottle decant.

Delicious middle of the road Margaux that is my "go to" on a normal evening. Drinking the 375's right how and giving the 750's a bit more time. I'll try to stock up on a few more of these if I see them on the secondary market. Great QPR.

To be honest this really needs another few years to be ready to drink. However, that said, it is already irresistible with sufficient decanting.

Wonderful wine. Outstanding effort from this estate. I have found the 2015’s needing more time than the Left Bank (as well as Right) 2016’s. This one opens nicely with a decant but I’d recommend waiting a year oft two until 2026 or 2027. It was very popular last night at a big wine wedding - but perhaps more in the bones and potential than full realization at this time.

Decanted and back into the bottle an hour before - Pours deep, inky garnet. Licorice, tar, violet, rose, cigar box, black cherry, a bit of sous bois, granite, and top soil on the nose. Palate carries over, accentuating spice, herbs, and black cherry. Bristly tannins, fairly heavy body, and a nice spike of acidity brace this for a long life. I like it now, but I'd probably let the next bottle sleep for another 5-7 years, then expect it to …

I’m a high fan of 2nd wines of great estate, they offer in my opinion delicious wines at good prices. As does the La Sirene de Giscours, a blend of 65 % CS, Merlot 30 % and 5 % CF. Bell pepper of the CF, tobacco leaf, black currant, leather, blackberry, medium plus body, dried black fruit finish.

1st bottle from a half case. For decades Giscours was a perennial underperformer given its potential and this vintage marked a level of excitement (and scores) not previously seen en primeur; so I got a half case. Since then the quality improvement has been sustained and now there are several vintages where excellent QPR Giscours can be bought for under £50 a bottle delivered. Fresh nose of bramble and blackcurrant. Fine and balanced on the palate with a deeply penetrating …

Smooth right from opening. This is the 7th bottle I’ve opened over the past 6 years, and this is the first one that did not need any meaningful decanting. Tannins are well blended. Probably just past its peak and very unlikely to improve. Should drink now. I’ll be consuming the rest of my bottles this year. But they could probably hold up for a bit longer.

Decanted in small decanter for 40mins. Paired with Braised beef. The wine's got a pink edge, like a sunset on a rough night. Violets and roses hit your nose first, soft whispers of something sweet. Then the creamy berries, cherries, flint and plums jump in, with a hint of spice that keeps things interesting. It's smooth on the tongue, velvety like an old leather jacket that's seen a few bar fights. That spice kicks back in the mid-palate, adding some …

Two hour decant, clear dark cherry in color, minerals, plum and cinnamon on the nose. Licorice and pencil shaving on the start with tannic build throughout medium length finish. Paired with smoked fowl, roasted herb carrots and potatoes. Lovely, easy drinking and unlikely to improve.

Really coming together nicely after just 35 minutes of air, this wine is a smooth operator. Bursting with blueberries, a kiss of flint, prunes and cassis, it has that chalky edge that makes you sit up and pay attention. The finish stretches on like the lingering scent of a cheap perfume that won't let go. I had it again at Bouchon Bistro, paired with a Snake River Farms American Wagyu ribeye, sautéed mushrooms, and spinach swimming in béarnaise sauce, with …

Had at Bouchon with steak frites. Aerated for 45min. Very nice. Thoroughly enjoyable. Tons of graphite/flint which I love from certain Margaux wines. Dark cherry, blueberry, soft tannins, hint of anise, and fine mouthfeel. Medium bodied with long finish. Will get again. Nice 2nd wine. Drink now.

Decanted and back into the bottle for 4 hours. Dark magenta, not showing much in signs of age. Pencil shavings show up first on the nose, with soubois, dark cherry, rustic oak, dusty gravel, and tobacco leaf. Palate is both fruity and herbal, with a nice merlot roundness. Feels like this will peak early. I like it now, but probably best in 2-3 years.

Nice drink. Not complex, but good. Some unusual aromas for Margaux and Bordeaux in general in my experience (green apple most prominently). No Bordeaux must. Obviously Cabernet-based. Alcohol a bit on the high side. But, again, enjoyed with a piece of grilled salmon.

Flavor intensity med-, finish is med-. Flavors include black cherry, black plum and vanilla. Some bitterness on the finish that suggests uneven ripeness.

Entre Grenat et Rubis d'intensité moyenne +. Nez assez discret à l'ouverture : poivron vert, vanille léger. La bouche est austère avec aussi un coté très végétal. Cependant un peu plus agréable après quelques heures : cassis, cèdre, fumé léger.

Average 2nd wine, I’ve tasted better ones for the price, a bit unbalanced on the palate throughout with too elevated alcohol and a bit harsh tannins. Nose is the best part, black fruits, cherries, plums, currants, cola, tobacco, cloves, chocolate. Finish is short and a bit bitter

EEE March. 2020; Bordeaux GCC; 1st and second wines randomly (@ MG) : Beautiful bouquet with dark berries, toast and caramel. On the palate red and dark berries like ripe blackberries and blueberries, good acidity, some bell pepper, smoke and toast. Good complexity. Still very youthful, but a beautiful second wine. 90+

Certainly approachable already but it's not at its peak by any stretch and there is frankly little to justify the $40 price tag yet. Hold for a year or better a few.

Much better from bottle than from barrel, the wine is forward, and ready to offer all its sweet, fresh, soft, red fruits and light floral notes with ease. Drink this while waiting for its big brother to develop.
