Milk Pitchers for Steaming: 12 oz or 20 oz, Spout Shape and What Actually Matters

A pitcher is one of the cheapest things on your counter, so the sensible question is whether you need one at all. Many machines come with a jug. You only need another if yours is the wrong size for your drinks or if you make two at once. The accessories page sets out where this sits in the buying order.

For the pitchers we link, we only have Amazon listings, so they are options and not picks. We have not used them. Our recommendation is about the size, and any plain stainless pitcher of that size does the same job. How we compare explains the “Seller data only” label.

Amrules 12 oz pitcher

A plain 12 oz frothing pitcher, per the listing title.

Seller data only: We only have the Amazon listing for this product. We list it as an option, not as a recommendation.

Why here: 12 oz is the size that suits one small milk drink, half filled. It only has to be stainless, with a spout you can pour from.

Check your box first

So 16 oz is common in the box, and half of it is 8 oz of milk, which is enough for most single drinks. If your machine has a jug that size, a second pitcher mostly helps if you want a smaller one for small drinks or a larger one for two at a time.

Listings say little about pitchers, and the size is the one number that counts here.

Size: work back from your milk

Gaggia's manual tells you to place the jug half filled with cold milk under the wand, and that's a handy rule for choosing a size. CASABREWS' CM5418 Basic manual adds that milk doubles in volume, so a half-full jug leaves room for that. Italy's certified cappuccino grows less, from 100 ml to about 125 ml, so how much the milk grows depends on how much air you let in.

The right-hand column is our reading of the math and not a standard. The first figures to check are your own: pour your usual drink's milk into a measuring cup, then double it. CASABREWS uses about 4 oz (120 ml) in its example, and Italy's cappuccino uses 100 ml. For a sense of how much milk each drink takes, see flat white or latte. A flat white uses less milk than a latte, and shot type and size differ by café.

Too little milk can be a problem too. If the wand tip can't sit below the surface, you can't get a clean spin going, and Breville's booklet says the milk should cover the tip. A pitcher that is far too large for your milk makes that harder.

What you're after in the jug

Glossy, paint-like milk with no visible bubbles. That comes from the steaming, not from the pitcher, and how to steam milk covers the technique. The pitcher only has to give the milk room to spin. If you want the vocabulary, our page on microfoam explains it.

Read how to steam milk

Big bubbles are a wand problem

Gaggia's manual says that if the nozzle isn't deep enough, big bubbles form and then disappear at once. If it's in too deep, the milk won't froth. So before you blame the pitcher, adjust the depth of the tip. A new jug won't change that.

Shape and spout: what is actually known

Gaggia's manual is the most specific maker statement we found. It recommends stainless steel, circular, rounded jugs that are narrower at the top, with a spout, and says the spout is needed for cappuccino decorations. It doesn't go further than that.

Shops sell pointed and rounded spouts for different patterns. We found no test that compares them, so we won't tell you one is better. If you are learning latte art, choose a size you can control with one hand. A plain pitcher is a fine place to start.

CASABREWS gives one more useful number for small wands: it recommends a jug 70 to 75 mm across, about 2.8 to 3 in, for the CM5418. Check that against your wand's reach. It's a figure for that machine, and we saw no maker publish one for other machines.

Stainless steel, and your hand as the thermometer

Gaggia's manual says to keep a hand on the rounded part of the jug to feel the temperature rise. Breville's booklet says the milk is ready at 60 to 65 °C, about 140 to 149 °F, when the jug is hot to the touch. Italy's cappuccino is steamed to about 55 °C. So a metal jug tells you what's happening, and a thermometer is optional.

The options one by one

Amrules 12 oz

The Amrules 12 oz pitcher^* is listed as a plain frothing pitcher in silver. That size suits single small drinks, which is what most people make at home. We only have the listing, so check the spout and handle in the photos.

Stainless pitcher range

The stainless pitcher range^* runs from 8.5 oz to 66 oz, per the listing. Pick your size from the table above. The 66 oz end of the range goes far beyond what the half-full rule calls for at home, so stop well short of that.

Common mistakes

• Buying before opening the box. You may already own a good jug.
• Replacing a jug the manual tells you to keep. Check first, especially with an automatic wand.
• Going too large “to be safe.” Too little milk in a big jug is harder to steam.
• Filling to the spout. Leave room for the milk to grow.
• Expecting a spout to fix your texture. Big bubbles come from the wand depth.
• Starting warm. Gaggia and Breville both start with cold milk. Gaggia also warns that the steam shouldn't run for more than 60 seconds at a stretch on that machine.

Steam and hot metal can burn you. Follow the warnings in your own manual, and move your hand to the handle once the jug gets hot.

Which to buy

If your box has a jug and it fits your drinks, buy nothing. If it doesn't, get a 12 oz pitcher for one small drink, or a 20 oz one for bigger or double batches. Then spend your effort on steaming milk, which is where the texture comes from. Still choosing a machine? The start page sorts them by what you drink, and these four questions end in one machine:
