Help please with precision brewer

Recommended Posts

Hey everyone, I hope someone can assist me with this problem. 

I'm using precision brewer for some time now, I'm getting great results now that I couldn't achieve for the first month of using it. 

When I brew small batches like 300ml (20g coffee) bed in the basket is flat, taste is sharp and smooth nice flavour. When I brew slightly bigger batch, 600ml bed looks like that and there is too much of bitterness in coffee. I'm using comendate mk3, 24 clicks I was using for 300ml, and tried the same for 600ml but there was that crater, ever since I have been increasing step by step clicks now with 30 and it's all the same. Light roast, union hand roasted coffee.

I find the same with larger batches on the Sage brewer - I think the showerhead is a little narrow for the larger size beds so by the time the drawdown happens, you end up with more water focused in the center of the brew. If it didnt make a mess id swirl the brew basket when it takes breaks between pours!


Saying that I've still had some great results out of the 36g in 600ml water and just grind slightly finer (Around the beginning of Aeropress on a Wilfa Svart grinder) 


I might fit the v60 shower adapter to mine and see how it gets on with larger v60's.

Can you tell me what settings you're using to get this outcome on your Precision Brewer? I've never managed to achieve great results with mine. Has led me to mainly doing manual pourovers instead of using the Sage. Are you using the custom brew settings? I'd love as much detail as you can manage!
