FAQ

Ordering

Do you sell tea or coffee?

No. We sell brewing equipment only. You'll need to bring your own leaves and beans.

How do I know which variant to pick?

Where a product has multiple versions, the differences are described on the product page. If the page doesn't make the difference clear enough to choose, that's a fault on our end — message us and we'll answer directly and fix the page.

Can I ask a question before I buy?

Please do. We sell final-sale, so we'd much rather answer questions up front than have you receive something that isn't what you expected. Email help@krestaco.com and you'll get a real answer.

Can I change or cancel an order?

Yes, before it ships. Orders can be cancelled for a full refund any time before they're passed to the warehouse — usually a window of several hours, and same-day cancellations are almost always possible. Email us with your order number as soon as you decide. Once an order is released to fulfillment it can't be cancelled.

Shipping

Where do you ship?

Currently the United States only.

How long does delivery take?

Most orders arrive within 7–8 business days of being placed. That covers both warehouse processing and transit. Full detail on the Shipping & Delivery page.

Is shipping free?

Yes. Shipping is free on every US order, with no minimum and nothing added at checkout. The price on the product page is the price you pay.

Will I get tracking?

Yes. A tracking number is emailed when your order ships. If it hasn't arrived within a day of the shipping confirmation, check your spam folder before contacting us — that's where it usually is.

Returns and refunds

What's your return policy?

All sales are final. We don't accept returns or issue refunds for change of mind once an order has shipped. Cancel before it ships and you get a full refund — after that, the sale stands. Full detail in our refund policy.

Something arrived damaged.

We'll replace it. Glass occasionally doesn't survive transit — send us a photo of the damage and the packaging within 48 hours of delivery and a replacement goes out at no cost. No need to ship the broken item back.

My item is defective.

Final sale covers change of mind, not faulty goods. If an item doesn't work as described when you first use it, contact us within 14 days of delivery and we'll replace or refund it.

I received the wrong item.

Tell us and we'll send the correct one at our cost, including return postage on the wrong one.

My tracking says delivered but nothing arrived.

Check with neighbours and around the property first — carriers often leave parcels out of obvious sight. If it hasn't turned up after 48 hours, contact us and we'll open a claim with the carrier.

Using and caring for the gear

Is the glassware dishwasher safe?

Handwashing is safer for anything with a stainless mesh filter — dishwasher detergent is harsh on fine mesh and shortens its life considerably. Warm water and a soft brush works better and takes less time than you'd think.

My glass has cloudy staining.

That's mineral scale from hard water, or tannin from tea. Both come off with a soak in equal parts white vinegar and warm water for about an hour, then a rinse. Repeat rather than scrubbing — abrasives scratch glass permanently.

Can a hand grinder handle espresso?

It depends on the burr and the number of grind settings. Espresso needs a fine, very consistent grind, and not every hand grinder adjusts finely enough. Check the product page for the grind range before buying for espresso specifically — and ask us if it isn't clear.

What water temperature should I use?

Broadly: green tea around 175°F, oolong around 195°F, black tea and coffee at 200–205°F. Boiling water scorches delicate leaves and pulls bitterness out of coffee. A temperature-controlled kettle handles this for you; otherwise, boil and wait a minute or two.
