Each meal included a white and a red Bordeaux (usually from area we were that night). Nothing collectible or expensive, but decent 10-20 euro type wines
Whites
2015 Chai des Bordes Bordeaux Blanc
Assume mostly SB, quite grassy but fresh, bright acids, light, grapefruit and catpee. B/B-
2012 Ch. de Chantegrive Blanc
Fuller than most, seemingly more Semillon than others, ripe tropical fruit, nutty. Good, just needs a touch more acid. B
2014 Ch. Moulin de Launay (Entre des Mers)
Bright, easy, citrus and grass. Simple but quite tasty. B
2014 Cuvee Clemence Cheval Quancard
Floral, some oak, good length. B
2011 De la Grave Grains Fins (Cotes de Bourg)
Not sure I’d ever had a Bourg white before. Vanilla, somewhat clumsy oak, almond and lemon. I think server said all Semillon. C+
2014 Cheval Quancard Reserve
Pit fruits, oak, good acids. B/B-
2015 Ch. Pouyanne (Graves)
Bright, fresh, grapefruit and peach with grassy accents. With Cap Ferret oysters, great match. B+
Reds
2012 Chai des Bordes Bordeaux
Red plum, leather, mild tannin, soft acid, short C+
2012 Ch. des Reuilles
Some cassis, soft, a little vanilla. B/B-
2010 Ch. Lauzette (Haut Medoc)
Some grip, blackcurrant and a little smoke, sturdy. B
2012 Haut Logat (Haut Medoc)
This was the blind wine in a tasting challenge. Fun format (though I thought not best questions) for a big group (60-70 people)- two choices each question, straight elimination. It was down to about 5 of us when question was 12 or 15 months oak aging, 4 of us opted for 12 and were eliminated.

Black plum, a bit of oak, tobacco. B
2010 Ch. Canteloup
Big, good tannic/acid balance, long finish. B/B+
Vintage? Cheval Quancard Reserve
Plump, ripe, oaky. B-
2012 de Marsan (Castillon)
Quite popular, but I thought short and clipped, and even wondered if corked (at a restaurant in Cap Ferret, not on ship) C+ if correct
One night there was a Sauternes as well, the 2012 Lafleur Mallet. Not too impressive- fruit cocktail, soft,rather short. C+
Each day had excursions (walking or motorcoach). On the penultimate full day, group divided into 3 groups on motorcoachs. After a tour of the Medoc from St Estephe down (fun to see so many chateaux I’d been drinking for years) my coach ended up at Ch. Giscours (I was happy, preferred to other buses going to Marquis du Terme and Prieure Lichine). Very good tour guide, nice tour of the winery, and then a short tasting
I neglected the vintage on the Ch. Duthil, a Haut Medoc from same owner as Giscours. Bright, higher acid, plummy, but not very long. B-/C+
2010 La Sirene du Giscours
Light touch of vanilla, black plum and cassis, modest finish, some tannin still. B
2010 Ch. Giscours
I had thought the 2009 Giscours overripe and overoaked, but this showed very well though young. Rich, deep, fleshy blackcurrant and blackberry, hint of leather. Needs time but very nice Margaux in a “mid-modern” style. A-
Then on to Ch. Kirwan for a dinner. With onion soup, the 2015 Signatures (Bdx Blanc). Citrus, grass, a little quincey note, soft. B-/C+
2012 Les Charmes de Kirwan
Redder fruit, some spice, tasty and easy. Good with a salad with duck breast and confit B
1995 Ch. Kirwan
With veal medallions with mushroom sauce. Some didn’t like, but after a week of young Bordeaux I was happy to have something with tertiary notes. Black plum, cedar, tobacco, moderate length, resolved and ready. B+
Overall, a fun week. If I had planned better I’d have hit a wine store in city of Bordeaux first day (free corkage). The overall Viking river cruise experience was very good. I have no desire to go on an ocean cruise, but this - a new town every day with lots of time to walk and explore- was fun. We did one “supplemental” excursion, a trip to Arcachon/Cap Ferret where we did a boat ride around Ile aux Oiseaux, visited an oyster farmer (fascinating), etc
Grade disclaimer: I'm a very easy grader, basically A is an excellent wine, B a good wine, C drinkable. Anything below C means I wouldn't drink at a party where it was only choice.Furthermore, I offer no promises of objectivity, accuracy, and certainly not of consistency.
