We just bought ours last week. This was a bit of a surprise because of its size very small compared to insulated carafes using conventional technology. But, after all, shape determines surface area and the closer to a sphere you get the less surface area you have across which to exchange heat. A good thing. But I was somewhat skeptical about the insulating properties of its all metal design. Here is what I found:Rinse and fill carafe with boiling water. Ambient temp 72 F.
Temperature at filling: 211 F (We live close to sea level.)
1 hr 15 min: 200 F
2 hrs 15 min: 194.9 F
3 hrs 15 min: 189.9 F
6 Hrs: 177.3 F
But who fills a carafe with boiling water? I rinsed the carafe with hot tap water (138.8F). More like what I''d actually do. I took coffee from our old Krups coffee maker which holds it at 175 F on its hot plate and filled the carafe about 3/4 full.
Temperature at filling: 173.0 Ambient temperature 72 F.
2 hrs: 166.1 F
3 hrs: 160.8
7 hrs 15 min: 136.9 F
This heat retention performance is excellent in my estimation, keeping coffee in the drinkable temperature range for up to six or seven hours. Much better than the glass lined carafe we had. Of course, some like it hot and some like it hotter. So I thought it would be helpful to see numbers. This is the carafe you need for any beverage you want to keep hot or cold as long as possible. Thermax insulation is a vacuum space where all the air has been removed from between two layers of stainless steel. It is the most efficient and compact form of insulation you can get in a carafe, and it''s unbreakable.
This type carafe beats any of the foam or glass models hands down, but it''s more expensive, too. I had a glass model for years and years, and this one holds more liquid in a smaller sized pitcher and it keeps it hot for much longer. As an example, I''ve gone back to the carafe after about seven hours and poured the last cup of coffee that was just as flavorful and almost as hot as it was when it went in the carafe.
Now here are some things to think about. First, the within described product (the Nissan TGS1000) is a 1 liter or 34 ounce size. It will NOT hold 10 to 12 cups of coffee; the standard measure for a coffee cup is 6 ounces so this model will hold just over 5 cups. The carafe you want for maximum capacity is the Nissan Thermos TGS1500 that is 1.5 liters or 51 ounces; it will hold just under 12 cups.
Second, while the product is described as dishwasher-safe, you don''t want to put it in the dishwasher. The exterior has a clear coating that will dull and chip off in the dishwasher. The best way to maintain it is to scrub the interior with a bottle brush, and, if you use detergent, rinse very thoroughly.
Third, the screw-on stopper is quirky. It seals very well to help keep in heat since heat rises even in an insulated carafe. However, it uses a push lever to dispense the liquid and then the stopper does not drain well for dispensing or cleaning. The best way to clean it is to rinse and then shake out all the water so it dries between uses.
The bottom line...this product does an admirable job of keeping beverages very hot or very cold for long periods of time and it looks nice. It''s just not very easy to clean.
Buy Thermos Nissan Stainless Steel Carafe Now
I bought this carafe to keep coffee hot without it being on a hot plate. It does a pretty good job at this. The coffee seems to cool quite a bit at first (I preheat the carafe as recomended) but then maintains a respectable temp for several hours. The spout will always dribble down the side of the carafe no matter how careful you are and it seems that some coffee always gets trapped in the cap. If you lay the cap on the counter when you remove it be prepared to wipe some coffee, but that should be no problem since you will probably already have a wipe in your hand to wipe up what has dribbled down the side.This seems like a poor review but it isn''t. These are minor problems and overall I am verry happy with this carafe. It does what it is supposed to do, looks great and sits solidly on the counter. It is a welcome addition to my kitchen and I would recommend it to anyone.

This is the Thermos Nissan carafe which retails for ~$50. Shake it all you want, it won''t spill a drop--unless you press the lever to pour. Pour coffee single handed, and it''s intuitive--no questions on how to pour. Keeps my home roasted coffee hot for hours, and because it''s stainless steel, there are no off flavors added to the beverage inside. A great buy.I''ve had this product for over a year now, and it''s in like new condition. Highly recommended even though the price has jumped--mine was $33.75.
Want Thermos Nissan Stainless Steel Carafe Discount?
We owned both Thermos Nissan and Zojirushi Premium Thermal Carafe. Here is a comparison of the two products:Heat retention:
Some people claim that Thermos Nissan keeps heat better. We did a careful head to head comparison -hot water in each, and then tested after 1 hr, 2hr, overnight. We did not notice much of a difference until we were exhausted and gave up on further testing.
Size & weight
Both hold 1 liter (34oz). However Thermos Nissan is half of outside measure of Zojirushi (mainly the height). Zojirushi''s bulky size is due to its inside glass unit plus outside shell. For the same reason, Thermos Nissan 34oz is also much lighter.
Pouring:
W/ Thermos Nissan, you need to continuously push down a lever while pouring. This is not a problem for 34oz one, but is a bit inconvenient when holding a bigger size Nissan. Zojirushi''s open/close button does not have this issue.
Durability:
Thermos Nissan is made of steel, so not breakable. Somebody mentioned that the seal at mouth will need replacement eventually. We don''t know how soon that would be. We have owned the Zojirushi carafe for 14 years, and it is still working properly.
We have Zojirushi at home and bring Thermos Nissan to the office. We have quite happy w/ both of them.
