Champagne Glasses for Hotels: Where the Capacity Hides and Why the Weight Is Missing

Two Weights Decide the Invoice, and Only One of Them Is Printed

A stemmed glass reaches a hotel through two documents, and they weigh it differently. The quotation weighs the glass: so many grams of polycarbonate or acrylic, so many pieces. The freight invoice weighs the consignment: the space the glass takes up once it is boxed, which is almost never the same number and is frequently the larger one. Buyers who build a landed-cost model on the glass alone are modelling the smaller of the two figures, and on this shelf the gap between them runs to nearly a factor of three.

That would be a manageable problem if both figures were on the page. On the 35 rows that make up the champagne and stemware shelf, one of them is not. Cartons are published almost everywhere — 33 of the 35 rows give a box size and a pack count, so a chargeable weight can be worked out for almost the whole line. Net weight per glass is published on ten rows. The published half is the half your forwarder bills; the missing half is the half you are actually buying.

This guide takes the line apart in the order a purchase runs. First what the catalogue records and what it leaves out, then where the capacity figure has actually been hiding, then how to build a chargeable weight out of the box size that is printed, and finally the one rule that should govern any enquiry into a stemware programme: the price per piece and the price per kilogram are two separate questions.

What the Catalogue Records, Field by Field

Before reading any individual row it is worth knowing which fields the catalogue fills in and which it does not, because the empty ones are consistent rather than random. Across all 665 published products, the specification table uses eleven field names.

Weight is the second-rarest field in the catalogue and the rarest one that anybody would want to buy against. Fifteen rows in 665 declare it. They are not scattered: ten belong to this stemware line and five to the tumbler and cup range, which means the one figure that decides what a consignment weighs has been written down for 2.3 per cent of the shelf, and only on the two lines whose product is held in the hand.

The pattern is not an accident of typing. Material is declared on 661 rows and a model number on 613, because those two fields are what a buyer uses to identify the goods. Carton size appears on 303 rows, because freight is a conversation the supplier expects to have. Net weight appears on 15, because almost nobody asks for it until the first air shipment has been quoted.

Where the Capacity Has Been Hiding All Along

The champagne shelf publishes a capacity on twelve of its 35 rows. That is a small number for a product whose entire purpose is to measure a pour, and it sends buyers to the size field to work the volume out from a diameter and a height. Before doing that arithmetic, look at the photographs.

Every product image on this site carries a descriptive filename, and the filenames of this line carry the capacity. BY-9911A’s photographs are named …wine-goblet-346ml…; BY-9913A’s are …champagne-flute-170ml…; the BY-9914 pair reads 110 ml and 210 ml; BY-9915 reads 160 ml; BY-9916 reads 180 ml. Ten rows publish no capacity in the table and state one plainly in the image filename — and in every case where both the table and the filename give a figure, the eleven pairs agree exactly. The number was never unavailable. It was filed in the wrong place.

Add the two sources together and the coverage is 22 of 35 rather than twelve, which is enough to plan a beverage list from — and enough to expose a second problem. Where the table and the image disagree they do not disagree by a little. They disagree by the geometry.

Three pairs on this shelf are published with identical product dimensions and capacities that are not identical at all.

In each pair the printed envelope matches to the millimetre and the usable volume differs by between 1.6 and 1.9 times. A stem is not a cylinder, a bowl flares, and a coupe holds what a flute does not; the two dimensions the sheet prints cannot see any of that. Buy the row, not the envelope. And note where the answers came from: in the first pair and the third, only the photographs carry the capacity at all, so a buyer who reads specifications and not images would have ordered a 550 ml glass believing it had the geometry of the 346 ml one.

Ten Weights, and Six of Them Are the Only Acrylic Rows in the Catalogue

Come back to the ten rows that declare a net weight. Their distribution is stranger than the count. Six of them are the only rows in the entire catalogue whose material field reads PMMA — BY-9918-1, BY-9918-2, BY-9918-3, BY-9919-1, BY-9919-2 and BY-9919-3. Across 665 products, acrylic is named six times, and every one of those six rows also carries a weight. Four are polycarbonate — BY-9920A, BY-9920B, BY-9920D and BY-9920E — which happen to be the four rows of one graduated family.

The coincidence is worth pausing on because it shapes the rest of this guide. The two blocks that declare a weight are also the two blocks that declare a capacity often enough, and carton sizes, to be costed completely. Ten rows on this shelf can be taken from a photograph all the way to a delivered kilogram. The other 25 cannot, and no amount of arithmetic on the published fields will close the gap.

Building a Chargeable Weight From the Box You Are Given

The good news is that the freight half of the calculation needs nothing but the fields that are already printed. Take the pack count and the carton size, divide one by the other, and you have the volume of box that one glass occupies. That single derived figure — cubic centimetres of carton per piece — is the one to compare across a range, and it converts to a freight charge under either of the two conventions a forwarder will use.

• Air freight. The volumetric convention is 6,000 cm³ to the kilogram, so a glass occupying 2,345 cm³ of carton bills as about 391 g.
• Sea freight, less than container load. The convention is 1 m³ to 1,000 kg, so the same glass bills as about 2.3 kg per cubic metre — the same relationship, expressed differently.

Both routes produce the same ranking, which is why a single index is enough: cubic centimetres of carton per gram of product. Where it is high, you are paying to move air. Where it is low, the carton is doing its job. On this shelf the index is available for 33 of the 35 rows, and the spread across them is the whole of the freight argument.

From Fifty Grams to Three Hundred Ninety-One

Here is that calculation run across the stemware line, heaviest pack first. The final column is the volume of carton each glass occupies, and the one before it is what a forwarder bills for it.

The two ends of that table are both on the same shelf and both called champagne glasses. At the top, twelve boxes of the largest glass weigh a tonne on paper. At the bottom, twenty boxes of the smallest — 2,880 pieces — bill as roughly the same as one box of the largest. Going by carton volume per glass, the widest row is 7.8 times the narrowest, and because the calculation runs entirely off the published fields, none of that difference is visible in a unit price.

The observation that matters here is not that light glasses exist. It is that the very tall, very narrow shapes — BY-9912H at 4.5 × 7.5 cm, BY-9912G at 4.8 × 8.5 cm, BY-9914B in its shallower carton — are also the shapes that nest, which is why their cartons are small. A tall flute that does not nest pays for the air around it in every shipment of its life.

Ten Rows Where Both Figures Exist, and What the Gap Turns Out To Be

On the ten rows that carry a net weight, both halves of the calculation exist, so the relationship can be measured rather than guessed. The final column is the multiple by which the billable weight exceeds the weight of the goods inside it.

Every one of the ten is above 1.2 and one is nearly at three. That is the number a landed-cost model needs and almost never gets. A buyer comparing two quotations on price per piece, and choosing the lighter glass because it is cheaper, can easily be choosing the row that bills at 2.91 times its own weight over one that bills at 1.28 times. Whether that matters depends on the route: on a full container loaded to the roof the lighter glass is still the better buy, because you are paying for the box either way and the box is full. On air freight, on a part load, or on any programme where the freight is negotiated per kilogram, the rank order can reverse.

Nearly Twenty Grams of Carton for Every Gram of Acrylic

The ten rows also split cleanly down the material line, and the split is instructive. Divide carton volume per glass by net weight per glass and the acrylic block sits between 7.7 and 10.2 cm³ of box for every gram of glass, averaging 8.7. The polycarbonate block sits between 10.7 and 17.5, averaging 12.9. The billable multiples fall the same way: 1.28 to 1.71 for the acrylic rows, 1.78 to 2.91 for the polycarbonate ones.

It would be easy to read that as a statement about the two materials, and it is not. It is a statement about the cartons they were packed in. Two rows make the point without any material argument at all: BY-9918-2 and BY-9920A both declare a net weight of 200 g, and they are not similar shapes — the first is the wider glass at 9.3 × 21.2 cm, the second the taller one at 7.5 × 25 cm. The wider glass ships at 2,047 cm³ per piece; the taller one ships at 2,345, fifteen per cent more, in a carton 26 litres larger on the same 72-piece pack.

The practical consequence is that net weight cannot be used to predict freight. The heaviest row here is not the worst, and the lightest one definitively is: BY-9920E is the 109 g glass, the smallest in the family, and it carries a 137-litre carton for 72 pieces — very nearly the box that the 630 ml glass travels in. Small format does not mean small box, because the carton is sized to the stem and the foot as much as to the bowl.

The Same Shape, and a Hundred Millilitres Apart

Within the four-row family that carries both a capacity and a weight, the arithmetic of scaling is worth watching closely, because it is the thing that decides how a size ladder is priced.

Capacity rises 125 per cent from the smallest to the largest while weight rises 83 per cent, so the largest glass is the lightest per millilitre in the family and the smallest is the heaviest. That is not a defect; it is what happens when a foot, a stem and a rim are held roughly constant across a ladder and only the bowl grows. The consequence for a buyer is that a smaller serve in the same family is not proportionally cheaper to make, and a supplier quoting the family by millilitre will be quoting a curve rather than a line. If a beverage list needs two sizes from this family, price them as two rows.

It also follows that the smallest glass carries the least efficient carton in the set. BY-9920E moves at 17.5 cm³ of box per gram of glass, the worst index on the shelf, against 7.7 for BY-9919-2 — a difference of 2.3 times in the volume of air shipped per gram of product. Both are stemware, both ship 72 to a carton, and only one of them is doing anything sensible with the space.

Two Rows That Cannot Be Costed At All

Two rows on this shelf carry a model number, a product size and a pack count, and nothing else. BY-9921B at 5.3 × 25.5 cm and BY-9921C at 5.3 × 23.5 cm both list 72 pieces to a carton and give no carton size. They also omit the material field, which every other row on the line fills in, and they are the only two rows where the product photographs carry no capacity either.

The effect is that neither row can enter a freight calculation. There is a pack count and no box, so the chargeable weight is undefined; there is no resin, so the weight of the goods is undefined even in principle. They are, in the strict sense, buyable and not budgetable. That is not a reason to strike them off a list — but it is a reason to collect four figures before either one goes into a tender: the carton dimensions, the net weight per piece, the gross weight per carton, and the resin. Any of those four arriving blank turns the row into an assumption, and assumptions in a container plan are paid for at the destination.

Quote the Order Three Ways

There is a simpler test than any of the arithmetic above, and it takes one email. When a stemware programme is being priced, ask for the same order to be quoted three times: per piece, per kilogram, and per cubic metre. The first is the quotation every supplier can produce. The second and third require the supplier to know the net weight and the packed volume of what is being shipped, and to have them for the specific row rather than for the range in general.

A supplier who can answer all three is a supplier you can plan a landed cost with, because the three answers together expose the one figure that decides whether the programme works: how much of what you are paying to move is the product and how much is the box. A supplier who can only answer the first has given you a price for goods that have not yet been weighed, and the difference will be discovered on the freight invoice rather than on the quotation.

On this shelf, ten rows will survive that test as published. The other 25 need one question each, and the right question is not what does it weigh but what does a carton weigh when it is full. Gross weight per box is the figure that closes a landed-cost model, and it is the figure to put at the top of an enquiry about any stemware programme.

Questions Hotel Buyers Ask About Stemware Specifications

Why does the catalogue give a box size for almost every glass but a weight for only ten?

Because the two fields answer different questions. Carton size and pack count describe what the supplier ships and how it is loaded, so they are recorded as a matter of course. Net weight describes the product itself, and it is usually only written down when a buyer has needed it for a freight or duty calculation and the answer has been kept. Across the 665 products on this site, Weight is declared on 15 rows and Carton Size on 303. Anyone costing a shipment should treat net weight as something to request rather than something to look up.

The capacity on some products is not in the specifications table. Where should I look?

On the product photographs. Image filenames on this line carry the capacity for ten rows that the table leaves blank, and where both sources give a figure they agree in every case. Combining the table and the filenames takes the champagne shelf from 12 of 35 rows with a capacity to 22. It is worth checking before concluding that a figure is unavailable, and worth confirming in writing before ordering, because a filename is not a specification.

Two glasses are listed with the same dimensions but different capacities. Which is right?

Treat both as provisional and ask for the bowl and stem measurements separately. Three pairs on this shelf are published that way, with identical printed envelopes and capacities between 1.6 and 1.9 times apart. A diameter and an overall height cannot describe a flared bowl, a coupe or a tapered stem, so two shapes routinely print the same numbers. The capacity is the field to trust, and where no capacity is printed, a filled sample is the only reliable answer.

Does a lighter glass always mean cheaper freight?

No, and on this shelf the lightest one is the most expensive to move. Freight is billed on the volume the carton occupies once a weight threshold is passed, so what matters is carton volume per piece rather than grams per piece. The 109 g glass in the 280 ml family ships at 17.5 cubic centimetres of box per gram of glass; the 195 g glass in the acrylic family ships at 7.7. Per gram of product, the lighter glass moves 2.3 times the air. On a full container both are acceptable; on air freight or a part load the ranking changes.

What should be on the enquiry to get a usable landed cost?

Four figures per row: net weight per piece, gross weight per carton, carton dimensions, and pieces per carton. Ask for them against the model numbers you are actually ordering rather than as a range average, because a range spans more than one carton. Destination country and port belong in the same message, so that the freight side is quoted on the route you will use rather than on a generic lane.

The Rest of the Table Service, Read the Same Way

The stemware shelf is one row of a larger table service. The champagne and stemware range covers the coupes and flutes, the tumbler and cup range the unstemmed drinkware, the water jugs the table carafe, and the bar supplies the counter end. Where the deciding question is resin rather than shape, the materials comparison sets the three families side by side. Where it is which glass belongs in which hand, the stemware buyer’s guide and the three-spec-sheet guide take the same shelf from the service side, and the patterned drinkware guide covers what happens to all of this when the glass is moulded with relief.

The earlier stemware guide covers the service side of the same shelf — bowl geometry, the bubble clock, the stem as a temperature device and the wash cycle. This one covers the purchasing side. Read together, they answer the two questions that always arrive together: which glass holds a pour, and what it costs to get the pour to the table.

The floor on this line is 500 pieces per model. A row that is already tooled leaves the works inside seven to fifteen days; one that needs new tooling takes longer, and the difference belongs in a launch date rather than in a footnote. A logo, a tint or branded packaging is quoted inside the same production run instead of as a separate project. The moulding happens at our own works in Yongkang, Zhejiang province, and finished goods leave China through Ningbo or Shanghai.

To price a stemware programme, put the model numbers you are considering on the contact page together with the destination port and the route you expect to use, and the export desk will return the four figures per row — net weight, gross weight, carton size and pack count — along with the price. The About page covers how the tooling and the export side are set up if that is the open question.

Also on the stemware shelf: BY-9911C, BY-9912E, BY-9912F, BY-9913A, BY-9914A, BY-9915, BY-9916, BY-9916-1, BY-9917, BY-6631, BY-8008, BY-8009, BY-9226DZ. The four unstemmed rows that also declare a net weight are BY-8018, BY-8018B, BY-8020B, BY-8022B, BY-8022C, and the serve-size guide, the bar and milk-tea guide, the cup and tumbler guide and the beer glass guide take the same field-reading approach from the menu, the counter and the tap, while the ice service guide applies it to the bucket on the back bar.
