flat whites use a 1:3 espresso-to-milk ratio (160 ml) with thin microfoam, while lattes use 1:4 or 1:5 ratios (240 ml) with thicker foam layers.
the directory is yours to explore, and the passport is free.
the difference between a flat white and a latte comes down to milk ratio and foam texture. a flat white uses a 1:3 espresso-to-milk ratio (typically 30 ml espresso to 130 ml milk) for a 160 ml total serving, while a latte uses a 1:4 or 1:5 ratio (30-60 ml espresso to 180 ml milk) for a 240 ml drink. flat whites feature velvety microfoam about 0.5 cm thick, whereas lattes have a distinct foam layer of 1-1.5 cm on top.
flat whites maintain a concentrated coffee-forward profile with their 1:3 ratio. you get 30 ml of double-shot espresso mixed with 130 ml of steamed milk, creating a 160 ml drink where espresso flavor remains prominent throughout. the milk quantity stays deliberately modest to preserve coffee intensity.
lattes dilute espresso more significantly with their 1:4 or 1:5 proportions. a standard latte contains the same 30-60 ml espresso base but adds 180 ml of steamed milk, totaling 240 ml. that's 38% more milk than a flat white, which fundamentally changes how the drink tastes and feels. the larger milk volume makes lattes noticeably sweeter and milder, perfect for those who find straight espresso too intense or want a canvas for flavored syrups.
these ratios aren't arbitrary. they determine whether espresso or milk dominates your palate, making the choice between these drinks a matter of how much coffee punch you want versus creamy sweetness.
the foam layer separates these drinks as much as milk volume does. flat whites use microfoam, which is steamed milk with extremely fine, barely visible bubbles. when properly executed on a La Marzocco or similar machine, microfoam creates a glossy, paint-like texture that integrates seamlessly with the espresso below. the resulting foam layer measures just 0.5 cm thick, creating what baristas call a "flat" surface (hence the name).
lattes feature airier, lighter foam that sits distinctly on top of the drink. this foam layer ranges from 1 to 1.5 cm thick and contains larger bubbles than microfoam. you can actually see the foam as a separate layer when a latte is poured into a glass, whereas a flat white's microfoam blends almost invisibly into the milk beneath it.
the microfoam in a flat white requires more precise milk steaming technique. you need to introduce air only briefly at the beginning of the steam cycle, then focus on creating a smooth, silky whirlpool that breaks down bubbles into microscopic size. lattes are more forgiving since the visible foam layer is expected and even desired. many cafes in 2026 now use automated milk systems, but the best specialty shops still steam manually to control texture exactly.
when exploring different espresso drinks, pay attention to how foam affects mouthfeel. microfoam creates a velvety coating that enhances espresso's natural oils and crema, while latte foam provides a lighter, airier top note before you reach the milkier body below.
flat whites deliver significantly more espresso intensity per sip. with only 130 ml of milk diluting 30 ml of espresso, the coffee-to-milk balance stays heavily weighted toward coffee. you taste roast characteristics, origin notes, and espresso bitterness clearly throughout the drink. this makes flat whites ideal for showcasing single-origin espresso or lighter roast profiles where you want to appreciate specific flavor notes.
lattes taste noticeably milder and sweeter because 180 ml of milk softens the espresso considerably. milk's natural lactose sugars become more pronounced, creating a dessert-like sweetness that masks espresso's sharper edges. this is why lattes work so well with flavored syrups (vanilla, caramel, hazelnut) while flat whites typically don't need them.
the milk quantity also affects caffeine perception, though both drinks contain the same amount of actual caffeine if made with identical espresso shots. the flat white's concentrated format makes caffeine hit faster and feel more immediate, while the latte's larger volume spreads that caffeine across more liquid, creating a gentler delivery.
if you prefer your coffee drinks to taste primarily like coffee with milk as a textural enhancer, choose flat whites. if you want milk to be a co-star that softens and sweetens the coffee experience, lattes are the better option.
flat whites come in 160 ml (5.4 oz) cups, typically ceramic. this smaller format concentrates flavor and maintains the careful milk-to-espresso balance. you'll rarely see flat whites served in glasses, as the ceramic helps retain heat in the compact drink. most specialty cafes serve flat whites in 150-180 ml cups depending on their house recipe.
lattes arrive in 240 ml (8 oz) glasses or cups, though many shops offer larger sizes up to 350-475 ml for customers who want even more milk. the larger format gives you more to drink but dilutes espresso flavor proportionally. glass serving vessels are common for lattes because customers like seeing the distinct foam layer and milk-espresso gradient.
the size difference isn't about espresso volume (both drinks use the same double shot), but about how much milk surrounds that espresso. a flat white finishes in 5-8 sips if you drink it like a small, intense treat. a latte lasts 15-20 sips as a more leisurely, mild beverage.
serving temperature matters too. flat whites cool faster due to their smaller volume, so drink them promptly. lattes maintain warmth longer, making them better for slow sipping while working or reading.
steaming milk for flat whites requires more skill and attention than for lattes. you need to create silky microfoam by introducing minimal air (just 1-2 seconds of surface hissing) before submerging the steam wand to create a rolling whirlpool. the milk should reach 55-62°c, never hotter, or you'll scald the delicate microfoam texture. many baristas tap and swirl the pitcher after steaming to eliminate any remaining larger bubbles.
lattes allow more forgiving milk steaming since the visible foam layer is expected. you can introduce air for 3-5 seconds to create more volume, then texture the milk to 60-65°c. the slightly higher temperature works fine because you're not aiming for paint-like microfoam.
pouring technique differs significantly. flat white pours start close to the cup surface from the beginning, allowing microfoam to integrate immediately with espresso crema. the pour creates minimal separation between milk layers. latte pours often start from higher up, then drop closer for latte art, but the pour naturally creates more stratification between espresso, steamed milk, and foam cap.
espresso extraction stays identical for both drinks when made properly. you want 25-30 seconds of extraction time for a 30 ml double shot, whether it's going into a flat white or latte. some baristas pull slightly shorter (ristretto) shots for flat whites to intensify flavor, but this isn't universal practice.
order a flat white when you want espresso flavor to dominate, appreciate coffee origin characteristics, or prefer smaller, more concentrated drinks. flat whites work better in the morning when you want quick caffeine delivery with minimal liquid volume. they're also the better choice for tasting how well a cafe dials in their espresso, since there's less milk to hide extraction flaws.
order a latte when you prefer mild coffee flavor, want something to sip slowly over 15-20 minutes, or plan to add flavored syrups. lattes suit afternoon drinking when you want comfort and sweetness over intensity. they're also better for coffee newcomers who find espresso-forward drinks too bitter or strong.
cost differences are usually minimal. expect to pay $4.50-6.50 for a flat white and $4.75-7.00 for a latte at specialty shops, with lattes costing $0.25-0.50 more due to extra milk volume. chain shops often price them identically.
neither drink is objectively better. the choice depends entirely on whether you prioritize espresso intensity (flat white) or creamy mildness (latte). both drinks showcase proper espresso and milk steaming technique when made well, just with different balances and textures.
don't assume flat whites are just small lattes. the microfoam texture and milk ratio create fundamentally different drinks, not just different sizes. a properly made flat white should taste noticeably stronger and feel silkier than a latte, even if you poured less latte into a smaller cup.
avoid ordering flat whites at shops that don't train baristas in microfoam technique. many cafes simply pour small lattes with latte-style foam and call them flat whites, which misses the entire point. look for specialty shops with manual espresso machines (La Marzocco, Synesso, Slayer) where baristas control milk texture precisely.
don't add sugar or syrups to flat whites. the drink is designed to showcase espresso with just enough milk to create velvety texture, and sweeteners overwhelm that careful balance. save flavored additions for lattes where larger milk volume can support them.
don't let either drink sit too long. flat whites degrade faster due to their small volume and delicate microfoam, which separates within 3-5 minutes. lattes last slightly longer but still lose optimal texture and temperature after 8-10 minutes. both drinks are meant to be consumed immediately after preparation.
the flat white versus latte choice ultimately reveals what you value in an espresso drink: concentrated coffee intensity with silky texture, or mild sweetness with generous milk volume. both have earned their places in specialty coffee culture by serving different preferences equally well.
Key takeaway: a flat white is smaller and stronger with a 1:3 ratio and 0.5cm microfoam, while a latte is milder and larger with a 1:4 or 1:5 ratio and up to 1.5cm of foam.
not exactly. a flat white is smaller -- 160ml versus 240ml -- but the key difference is the milk ratio and foam texture, not just size. flat whites use a 1:3 espresso-to-milk ratio and velvety 0.5cm microfoam, giving a stronger, more coffee-forward taste that a small latte does not replicate.
they can be equal since both typically use a 30ml double-shot espresso base. however, some lattes use 60ml of espresso, which would make them stronger. the flat white tastes more intense because less milk dilutes the same espresso, but caffeine content depends on the shot size, not the milk volume.
the higher price usually reflects the skill required to produce proper microfoam. steaming milk to the tight 0.5cm texture a flat white needs takes more precise technique and practice than the airier foam on a latte. specialty shops charge for that craft, not just the ingredients, which are actually cheaper given the smaller milk volume.
yes, but results vary. oat milk steams closest to dairy and produces decent microfoam, making it the most reliable alternative for a flat white. almond and soy milk can separate or produce larger bubbles, which disrupts the velvety texture. barista-edition oat milks are specifically designed to hold microfoam and are the best choice.
