Green Coffee Beans for Siphon Brewing

Green Coffee Beans for Siphon Brewing

Siphon brewing sits between immersion and filter, combining the clarity of pour over with the depth of French Press. It’s a complex method that rewards experimentation - and when it’s dialled in, the results can be spectacular. These green coffees have been chosen for their fruit-forward character and rounded body, with Kenyan and Ethiopian lots standing out. While siphon brewing can handle most coffees, it really shines with those that offer bold flavour rather than subtle, acidity-led nuance.

  • What kind of coffee works best in a siphon brewer?

    Siphon brewers are ideal for coffees with bold flavour and good body - think fruit-forward profiles with depth and sweetness. Kenyan and Rwandan lots are a great fit, especially naturals or washed coffees with a strong character. More delicate, acidity-driven coffees tend to be better suited to a classic pour over.

  • How does siphon brewing affect flavour?

    Siphon brewing brings out both clarity and weight. It delivers a cup that’s cleaner than French Press but fuller than a typical filter brew. It softens harsh acidity and highlights layered flavours, making it perfect for coffees with fruit, florals, or spice.

  • Do I need a different roast profile for siphon brewing?

    A light to medium-light roast works well. You want to preserve acidity and aromatics while developing just enough body to support the cup. Too dark, and you may lose the complexity that siphon brewing is so good at showcasing.

Your questions, answered

What should I look for in a green coffee for siphon brewing?

Look for coffees with a strong flavour presence - fruit-forward profiles, clear sweetness, and moderate to full body. Kenyan and Rwandan coffees, particularly washed or clean naturals, are ideal. You want coffees that can hold their shape through a complex brew process.

Is siphon brewing good for all types of coffee?

Technically yes, but it's best with coffees that have depth and character. Subtle, high-acid coffees may lose some of their nuance, so they’re often better in pour over brewers. Siphon brewing excels when there's body and bold flavour to showcase.

Do I need to roast differently for siphon brewing?

Light to medium-light roasts are usually best. You want to keep the aromatics and acidity alive without under-developing the coffee. Roasts that are too dark can lose clarity and flatten the complexity siphon brewing is capable of highlighting.

What grind size should I use for siphon brewing?

A medium grind, similar to what you'd use for a flat-bottomed pour over, tends to work well. Too fine, and the brew can stall or over-extract; too coarse, and you risk underdeveloped flavours. Consistency is key.

Is siphon brewing hard to master?

It can be - it’s a more technical brew method with a bit of a learning curve. Controlling temperature, timing, and agitation all play a role. But once dialled in, it’s one of the most rewarding ways to brew a flavour-forward cup.
