Onyx Geometry review: washed Colombia and Ethiopia with two brew recipes

Geometry is a defensible first bag for a buyer who wants a light, floral and fruit-led coffee for both filter and espresso. Onyx publishes distinct recipes for both. Its Colombian and Ethiopian components change every few months, so the named flavor direction and recipe are a starting point, not a guarantee for the next bag.

Good fit

  • Light-roast filter and espresso in one household
  • A roaster-published recipe for each method
  • Buyers comfortable with a changing microlot blend

Think twice if

  • You want a low-fruit, chocolate-heavy espresso
  • You need a fixed farm or variety every order
  • You cannot allow time to dial in a light espresso

Exact bag and blend identity

Onyx defines Geometry as a washed Colombian and Ethiopian blend. It says its component coffees are updated about every two to three months to preserve a flavor target as harvests move. The current page calls the variety mixed. That makes the exact roaster and product stable, while the individual farms and varieties need a fresh bag-date check. [1]

The product page places Geometry on its light roast range and names filter and espresso as preferred extractions. A bag image identifies the product line; it cannot prove which Colombian or Ethiopian microlots are in a future delivery. The 10 oz selector is the sensible first purchase before considering the 2 lb or 5 lb packs. [1]

02 / 6

What the flavor evidence supports

Berries, stone fruit, Earl Grey and honeysuckle are Onyx tasting notes, not flavors Coffeedant observed. Onyx describes a rounded result despite the light roast. An independent older home-brewing account discusses a particularly expressive Geometry sample, but its bag date and recipe differ from the product panel checked here. It cannot establish a repeatable sensory score. [1] [3]

This is the bean to consider when fruit and tea-like cues are attractive. A buyer who calls those cues sour may prefer Southern Weather or an existing cocoa-led blend. One self-selected owner thread also shows how grind and bag age can affect impressions; it is context for uncertainty, not a satisfaction rate. [4]

03 / 6

Brew method and recipe fit

Onyx publishes a 25 g coffee to 400 g water Origami/Hario cone start at 205°F and a separate 19 g in to 45 g out espresso start. The latter is a beverage target, not 45 g of water added to the portafilter. Save separate grinder settings and adjust the actual bag against your basket and water. [2]

Light washed espresso may require careful grind and temperature adjustment on a machine with limited controls. The published recipe is an Onyx starting point, not a Coffeedant extraction result. For filter, keep the 1:16 ratio and change one variable at a time before deciding whether this fruit-led style fits you.

04 / 6

Roast date, storage and size

Check the delivered roast date and match it to the current composition. A 10 oz bag offers roughly fourteen 20 g filter doses before dial-in waste, so a mixed-method household can learn quickly without committing to bulk. Protect opened whole beans from air, heat and moisture; grind just before use. [5] [6]

The blend may change before your second order. Record the component panel, dose and grinder setting on the first bag, then treat the next delivery as a fresh dial-in rather than assuming an unchanged recipe. No package photograph establishes current freshness.

05 / 6

Value and availability at this check

The international storefront selector and US checkout context were not reliably aligned at this check. This review therefore gives no verified US price or discount. Compare the current 10 oz delivered total with the 10 oz or 12 oz alternative you actually buy, and confirm stock, shipping and roast date. [1]

Geometry earns consideration for two documented brew pathways and unusually clear component-change disclosure. If you only make a large chocolate-led latte, paying for a floral blend and then masking it in milk may be poor fit regardless of the displayed bag price.

06 / 6

A different bag for a different goal

Onyx Southern Weather has a more moderate roast and milk-chocolate brief; Onyx Monarch is darker and explicitly aimed at larger milk drinks. Geometry is the light, tea-and-fruit branch of that family. These are product-positioning differences, not a shared Coffeedant tasting ranking. [1] [7]

Counter Culture Apollo is another floral/citrus direction with its own rotating components. Read its full review if that flavor target matters more than Onyx’s published Geometry espresso and cone recipes.

Evidence and limits

How this review was made

This is a research-led US assessment of the exact whole-bean product. The current roaster listing controls identity and attributed notes. Independent samples and owner anecdotes are limited by their date, bag and recipe. Coffeedant has not bought, brewed, tasted, measured or photographed this coffee and assigns no numeric sensory score.

Sources were checked October 20, 2026. Check the delivered roast date, component panel, stock, exact size and checkout total. A package note is a starting expectation rather than a measured result.

Quick answers

What exactly is Geometry?

Can I use Geometry for espresso?

Onyx publishes a 25 g coffee to 400 g water Origami/Hario cone start at 205°F and a separate 19 g in to 45 g out espresso start. The latter is a beverage target, not 45 g of water added to the portafilter. Save separate grinder settings and adjust the actual bag against your basket and water.

The choice

Buy Geometry for its documented role

Geometry is a defensible first bag for a buyer who wants a light, floral and fruit-led coffee for both filter and espresso. Onyx publishes distinct recipes for both. Its Colombian and Ethiopian components change every few months, so the named flavor direction and recipe are a starting point, not a guarantee for the next bag. Start with a smaller whole-bean pack and let the delivered bag and your repeatable recipe decide any larger order.
