Recommended Posts

So on someone's reccomendation I've bought test tube/centrifuge tubes for single dosing. What does everyone else use? Anyone else use the test tube method?

@JollybeanThat the new ground coffee in the background, I struggled to dial that in. Where are your storage cellars from?

They look great, Where did you source the tubes?

Not the exact link I bought them from but these are similar.  Mine are by Jarvials and are 50ml.  They also do gold lids and 60ml if you need a slightly larger dose size.

Currently using the Craig Lyn Design ones which come in an aluminium holder. Managed to get them on offer at the time but the delivery and import stung me.

Maybe a silly question, but are these properly airtight? Do the lids have any sought of seal inside or are you just relying on the threads?

They have a plastic lining which seems to seal quite well.  They are watertight if you do them up well so I guess this means they are pretty airtight.

If you wanted to, you could save the valves from your coffee bean bags and when you have enough, drill a small hole in each of the caps and glue the saved valves onto the underside of each of the caps. Just an abstract thought after reading this thread - haven’t really thought this concept through, but it has the potential should it be a feasible, to allow the coffee beans to degas safely.

I'm looking at these amber ointment jars with black lid:

Can anyone suggest what size I should buy to store 20g of beans?

I bought similar and they were stated as 2oz (~56ml) and they were fine for medium roast 18g, enough headroom for an extra 2g
