Stones in Beans

dutchy101

So I came across the first stone in my beans today. Fortunately I saw it as I was weighing out into my dosing cup - made me thankful I’m using a single dosing grinder as if I had a hopper-fed grinder I doubt I’d have seen it.

Was wondering how common is it to find stones in your beans? This is the first I’ve had in 2 years.

Don’t think it’s overly common. I’ve not had a stone in my beans since I started the habit about 12 years ago.

Never seen one so far, although I always quickly check the weighed beans for an unknown object before chucking the beans in the grinder!

Inspector

i have had stone(s) in my beans in two different occasions so far.

Let your roaster know about it. i was also lucky as i was single dosing and spotted them before grinding.

I expect you’ll find DCs article on this from 15 years-ish ago if you look on the old wiki

They are more common with some origins and processes than other - e.g patio dried natural.

Systemic

Why you should always check your dose before firing it into the grinder. Roasters have kit to filter out foreign debris but some inevitably gets through. Over the years, have had three occasions when a small piece has popped up in the dosing cup. As @Rob1 says, it’s almost always confined to patio dried naturals.
