The server that knows the formula.
Borosilicate glass — heat-resistant, clean, no flavour transfer
Borosilicate glass handles thermal shock — you can pour near-boiling water directly from a dripper into a cold server without cracking. Unlike standard soda-lime glass, it doesn't absorb flavour compounds, oils, or odours between uses. The full transparency shows the colour and clarity of your brew from the moment it starts filling.
Extraction rate formula — printed on the glass, not a sticker
The body carries the extraction rate formula: TLM / TDS. The brew variable triangle — Pour Weight, Percentage, Yield, Time. Volume markings at 200ml, 300ml, and 400ml. A diagonal extraction curve. These are etched or printed directly onto the borosilicate body — not a label to peel off after the first wash. The server is a reference tool as much as it is a vessel.
Glass rod handle — full-length, stable grip for pouring
The handle is a solid glass rod running the full height of the server — the same material as the body. No plastic, no silicone sleeve, no separate component to crack or detach. The rod handle keeps your hand away from the hot glass body during service while maintaining the clean, uninterrupted visual of a fully transparent vessel.
700ml capacity — one to two cups from a single brew
At 700ml, the server comfortably holds a full pour-over batch — typically 400–600ml after a standard 1:15 or 1:16 ratio brew. Enough for one generous cup or two smaller cups without making a second brew. The tapered conical shape keeps the liquid warm longer by concentrating heat toward the centre of the mass.
Every cup is a formula. Here's how to read it.
The graphics on the server aren't decoration — they're the three variables that determine what ends up in your cup. Understanding them is the difference between guessing and dialling in.
What PW · P · Y · Tactually means.
The triangle printed on the server carries four letters. Each one is a variable you control every time you brew. Understanding all four is what separates dialling in from guessing.
Pour Weight
PW
The total weight of water used in the brew. Your starting variable. Determines the dose of solvent in contact with the coffee. Typically 15× the coffee dose for filter brewing.
Percentage (Ratio)
P
The coffee-to-water ratio expressed as a percentage. 1:15 = 6.67%. The ratio determines brew strength before extraction efficiency is factored in. A lower percentage produces a stronger cup at the same extraction yield.
Yield
Y
The weight of the brewed coffee in the server after the brew is complete. Not the same as Pour Weight — some water is retained in the coffee grounds. Yield is what ends up in your cup. Track it on the volume markings.
Time
T
Total brew time from first pour to drawdown. For a V60-style pour-over at 15g dose, target 2:30–3:30 min. Too fast means under-extraction. Too slow means over-extraction. Time is the most immediate feedback you have on grind size.

The vessel your pour-over deserves. Full transparency, heat resistance, and a formula etched on the body that reminds you what you're doing every time you brew.
Answered.
What does TLM / TDS mean?
TLM is Total Liquid Mass — the weight of the brewed coffee in your server. TDS is Total Dissolved Solids — the concentration of coffee compounds in the brew, measured as a percentage using a refractometer. Dividing TLM by TDS gives you extraction yield: how much of the coffee's soluble material ended up in the cup. The SCA targets 18–22%. Below that is under-extraction. Above is over-extraction.
Can I pour boiling water directly into it?
Yes — borosilicate glass is designed for thermal shock. You can pour near-boiling water (95–100°C) from a dripper directly into the server without risk of cracking. Standard soda-lime glass cannot handle this. Borosilicate is the same glass used in laboratory equipment and quality coffee drippers for this reason.
Will the formula printing wash off?
The graphics are printed or etched onto the glass body — not a paper label or adhesive sticker. They are dishwasher safe and designed to remain legible through regular use. Avoid abrasive scrubbing pads directly on the printed area to preserve the markings long-term.
How many cups does 500ml serve?
A standard pour-over brew at 1:15 ratio using 20g of coffee produces approximately 270–290ml of brewed coffee after accounting for liquid retained in the grounds. That comfortably fills one 250–300ml cup. For two cups, use 30g of coffee at 1:15 — producing approximately 420–440ml — which fits the 500ml server with room to spare. The 500ml server is sized for a focused one-to-two cup session, not batch brewing.
Does the glass rod handle get hot?
Glass conducts heat, but the rod handle's narrow diameter means significantly less thermal mass compared to the body — it heats more slowly and is safe to handle during a normal pour. For extended table service with very hot liquid, use a cloth or coaster. For the standard workflow of brew, pour, and serve, the glass handle is comfortable to hold.
