Orea V3 vs V4: Flat-Bed Pour-Over Recipes, Ratios and Grind Settings

Two Revisions of the Same Flat Bed

Orea's V3 and V4 are the same idea, twice: a wide flat coffee bed over a base that drains fast enough that grind matters more than pouring technique. The CUP-TIMER catalog carries twelve Orea recipes, and read together they reveal a consistent house style plus a few places where the V3 and V4 genuinely part ways. Every ratio, temperature and grinder setting below comes from a recipe you can open and brew.

What a Flat Bed Actually Changes

On a cone, coffee piles up deep in the middle and thin at the edges, so water entering the centre has far more coffee to travel through than water that runs down the wall. A flat bed evens that out. Bed depth is roughly the same everywhere, so the water front moves through the whole surface at a similar rate, and that is why flat-bottom brewers tend to taste repeatable rather than dramatic.

The trade is drawdown speed. A flat bed has more open area, and the Orea's base drains quickly, so contact time has to come from somewhere other than the brewer's geometry. On an Orea, that somewhere is grind size. You can see it in the catalog: almost every Orea recipe lands between 1:40 and 3:10 total, and the quickest finishes are the ones ground coarsest — the reverse of what a V60 drinker expects.

If you already brew on a Kalita Wave, your instincts about even beds and level pours carry over directly. The difference is that the Wave's pleated filter and three feet hold water back, while the Orea's flat filter sits on the base and lets it go.

V3 vs V4: What the Official Recipes Say

The V4 is the later revision of the V3, and Orea's own recipe cards treat the two as close relatives rather than different machines. Put the official entries next to each other:

• OREA V3 Base One — 12g to 200g at 1:16.7, 96°C, medium grind at 20–24 clicks, 2:30 total.
• OREA V4 Easy Does It — 16g to 260g at 1:16.3, 94°C, medium-coarse at 22–26 clicks, 3:00 total.

Same ratio band, but the V4 card runs cooler, coarser and thirty seconds longer on a dose a third larger. The second V4 entry, Orea V4 Standard, pushes the same direction: 18g to 288g at 1:16, 93°C, medium grind, three minutes.

Read as a set, the V4 recipes lean towards bigger doses (16–18g against the V3's 12g), cooler water (93–94°C against 96°C) and longer targets. The V3 recipe is the small, hot, quick one. That axis — dose up, temperature down, time out — is the useful way to move a recipe between the two, and it beats guessing at hardware differences you cannot measure at home.

Every Orea Recipe, Side by Side

Ignore the two outliers at the bottom of the ratio column for a moment and the pattern is tight: eight of the twelve recipes sit between 1:16 and 1:17, and nine of them finish in under three minutes. For a brewer with this much flexibility, that is a narrow house style.

Grind Does the Work Here

Nine of the twelve recipes specify a grinder setting, and the spread is the most instructive thing in the table: 20–24 clicks at the fine end, 29 clicks at the coarse end, with two recipes giving actual particle sizes — 490µm for the Wölfl recipe, 1000–1100µm for Clarimento Hot. That is a very wide window for one brewer.

Two caveats before you dial anything in. Clicks are grinder-specific, so read them as relative positions inside each recipe rather than as settings you can copy across machines. The micron figures are the ones worth chasing if your grinder is calibrated, and the gap between them explains the times: Orea Hyangcho drains in 1:40 at 29 clicks, while the finer Wölfl recipe holds on for 2:20 at 490µm despite pouring 70g more water.

The practical version: if an Orea brew tastes thin and sour, grind finer before you change anything else. If it stalls and turns dry and bitter, go coarser. On a fast-draining flat bed, grind moves the cup further than pour technique does.

Water Temperature Runs Cooler Than You Would Guess

The catalog spreads from 92°C to 98°C, and the distribution is lopsided. Four Orea recipes sit at 92°C, and the only entry at 98°C is a roastery recipe. That is noticeably cooler than the boiling-water school of flat-bed brewing you see on restricted-flow brewers.

It follows from the grind. When a recipe already runs medium-coarse to get a workable drawdown, pushing the water to 96–100°C on top of that overshoots — you get the harshness without the body. The recipes that do run hot compensate the other way: Assembly Coffee's Orea recipe pairs its 98°C with a medium-fine grind at 15g to 250g, which is the only combination in the table where heat and fineness rise together.

Starting point for a light roast you do not know: 94°C, medium, and adjust temperature only after grind is settled.

Competition and Roastery Recipes on the Orea

Two competition recipes in the catalog are brewed on an Orea, and they are the two that break the ratio pattern hardest.

Martin Wölfl's 2024 World Brewers Cup recipe runs 17g to 270g at 1:15.9, 93°C, medium-fine at a measured 490µm, finishing at 2:20. It is the finest grind in the table paired with an unremarkable temperature — a clarity-first setup that leans on particle size rather than heat.

Shih Yuan Hsu's WBrC 2022 recipe goes the other way: 14g to 200g at 1:14.3 in two minutes flat, the strongest hot ratio of any Orea recipe listed. The catalog entry does not record a grind or temperature for it, so treat the ratio and the time as the takeaway and fill in the rest from a recipe you already trust.

Both sit alongside the manufacturer cards on the Orea brewer hub, which is the fastest way to see all twelve in one place.

The Iced Outlier

One recipe in the set is not a hot brew at all. Orea Clarimento Iced runs 17g to 160g of hot water at 1:9.4, 92°C, medium at 850–900µm, over 2:15 — the concentrate lands on ice rather than in an empty carafe, which is why the ratio looks so strong next to everything else in the table.

Its hot sibling, Orea Clarimento Hot, uses the same 92°C water and the same coarse-leaning philosophy at a normal 1:16.7 with 15g to 250g. Brewing the pair back to back on the same coffee is a genuinely useful exercise: it shows you what the Orea's fast bed does when you shorten the brew and double the strength.

Where to Start

• You own a V3 and want a default: OREA V3 Base One, 12g to 200g at 96°C. Small, hot, 2:30.
• You own a V4 and want a default: OREA V4 Easy Does It, 16g to 260g at 94°C. Forgiving, three minutes, coarse enough to survive a mediocre grinder.
• You want a bigger cup: Orea V4 Standard at 18g to 288g is the largest dose in the catalog for this brewer.
• You want to chase clarity on a light roast: the Wölfl recipe's 490µm grind at 93°C is the template.

There is one more thing the table will not tell you. Two entries share the name Easy Does It with the same 16g dose but different water totals — 260g on the V4 card against 200g on the other — so check which one you have loaded before you start pouring, especially if you are working from muscle memory.
