It's the fair question, and it's the one people ask most often. So here is the honest answer: it's a solid rod of stainless steel, and it works the way an ice cube works — minus the water.

Frozen steel dropped into a bottle sits in the middle of the wine and pulls heat out of the whole column at once, instead of trying to cool the glass from the outside in. That's why an ice bucket takes twenty minutes and this doesn't. It's not a battery, it's not a gel pack, and there is nothing in it to leak, melt or dilute.

The bit that isn't physics is the build. Ours is machined stainless steel with an acrylic pour spout — food-safe, dishwasher-safe, and heavy in the hand rather than hollow. 4.7 out of 5 across 1,422 reviews, and the most common opening line in them is some version of "I was sceptical."

Straight answer, no rounding up.

• 10–15 minutes in the freezer is all the stick needs. Leave it in there and it's simply ready whenever you are.
• In the bottle, the wine is cold within minutes — this is the part that matters, and it's the part nobody argues with.
• At the table it holds for a couple of hours, up to three if you're not sitting in full sun. In direct summer heat, expect less.

We'd rather say that than promise you an all-day bottle. Most people don't need one — they need the second and third glass to still be as cold as the first, which is exactly where a fridge-chilled bottle on a warm table gives up.

Two complete kits — six pieces in total:

• 2 stainless-steel cooling sticks. Food-safe, dishwasher-safe, built to live in the freezer.
• 2 acrylic aerating pour spouts. They push air through the wine on its way to the glass, and they pour drip-free.
• 2 wine stoppers. For whatever you don't finish.

Fits standard 750 ml bottles. One kit usually lives in the freezer; the second one tends to end up with whoever asks about it first.

Yes — and it's the whole trick, so it's worth saying plainly: pour your first glass, then drop the stick in.

The stick takes up room in the neck of the bottle, so a full bottle would simply overflow. Pour one glass, slide the chiller in, push the spout on top. That first glass is your reward for opening the bottle; everything after it comes out cold.
