Create custom blends and explore 250+ preset blends across roastery styles, café styles, and world traditions. Filter by brew method, personality type, or your current inventory to find the perfect combination.
Blending takes your roasting to the next level of complexity. Once you start combining different origins and roast levels, you discover how all those individual flavors interact to create something entirely new. Dialing in the perfect espresso blend where a punchy natural Ethiopian adds fruit-forward brightness to a chocolatey Brazilian base. Building a smooth, balanced daily driver that just works every morning. Crafting a cold brew blend with low acidity and deep sweetness that's incredible over ice.
Or getting experimental — recreating a traditional Turkish-style blend, trying an Indian Monsoon Malabar mixed with a Rwandan honey process, or exploring flavor combinations popular in parts of the world you've never visited. Blending turns roasting from a single-origin pursuit into an endless creative playground, and keeping track of what ratios worked (and what didn't) becomes just as important as tracking the roasts themselves.
Journey and Science modes include the Blending module. Craft mode focuses on the core roast-and-taste workflow and does not show Blending by default. Craft users can preview it by tapping “Discover more” in Settings, or switch to Journey mode at any time — your data carries across every mode.
The Blending module is where creativity meets data. Build your own blends by selecting component beans from your inventory and dialing in percentages, or explore a curated library of 250+ preset blends organized by brew method, style, and origin tradition.
The "Inventory Only" filter is one of the most useful features — toggle it on to instantly see which preset blends you can make right now with the beans you have on hand. Personality-based recommendations from the Java Geek quiz add another layer of discovery.
Post-roast blending is recommended because different origins have different densities, moisture levels, and optimal roast points. Roasting separately lets you optimize each component and re-roast just one if it doesn’t turn out. Rest the finished blend 3-5 days for filter, 5-7 days for espresso — flavors meld during this time.
Keep your first blend simple — 2-3 components is much easier to dial in than 4+. A common approach: a body-forward base (Brazilian, Sumatran) combined with a bright accent (Ethiopian, Kenyan). Track your ratios so you can replicate successes.
Component percentages must total exactly 100%. Start with 2-3 components — more complex blends with 4+ components are significantly harder to dial in. A common starting approach is a base bean (50-60%), a complement (25-35%), and an accent (10-20%). Keep notes on what works.
Over 250 preset blends are available across all categories. The Inventory Only filter prevents the frustration of finding an exciting blend only to discover you do not have the beans. Saving a preset as your own creates an editable copy — the original preset remains unchanged.
World Blends showcase how different coffee cultures approach blending — from Italian espresso traditions to Turkish coffee blends to Nordic light-roast combinations. These recipes provide a foundation you can adapt to your own taste preferences.
These are generic style archetypes — descriptive profiles of regional roasting and café traditions, not recipes from or endorsements of any specific commercial roaster or café. They are excellent for learning how professionals balance components for consistency and flavor complexity. Use them as starting points and adjust to your preference.
For best results, take the "Find Your Type" quiz in the Java Geek module first. Your personality type reflects your flavor preferences — fruity and bright, earthy and bold, balanced and smooth, etc. The 14 recommendations per type cover a range of brew methods and styles.
Different brewing methods extract coffee differently, so optimal blend composition varies significantly. Espresso blends often include more body-forward components. Cold brew blends lean toward chocolatey and low-acid profiles. Pour over blends highlight origin clarity.
Always duplicate a blend before making major changes so you can compare the original with the variation. Keep notes on what worked and what did not. Over time, your My Blends collection becomes a personal recipe book.
