Keeping beans in the bag or in the hopper?

I have a Baratza Virtuoso+. I generally weigh out the amount of coffee beans I want to use, drop them in the hopper, and grind long enough to grind all the beans up. The output weight is consistently within 0.1g with some pulsing and shaking of the grinder. (Single dose, baby! 😉)

The reason I do this is that for some reason I think it’s better to keep the beans sealed in the bag that they come in, rather than putting them in the hopper of the grinder and letting them stay there.

Is that right? Or am I being overly precious about how the beans are stored?

BTW, I’m not going to buy a container just to keep the beans in. The coffee bean bag will be more compact, especially as it gets towards the end.

wilburpan Light and oxygen are the main causes of bean deterioration, so an opaque and semi-sealed bag is in theory better than a transparent, unsealed hopper. Whether it makes any difference in practice clearly depends on how quickly you go through the beans; we tend to consume 80-120 g/day… which makes a 250 gram bag “in the hopper” not a problem. YMMV.

Exactly the same here. I transfer new bags to an airtight container and drop about 100g in the hopper each day.

You can’t go wrong with either of the above approaches.

I generally transfer beans from the bag into airvac containers once I’m ready to start using them but if you are using them within 7 - 10 days they will be fine either from the bag or another airtight container.

The only reason I transfer from the bag into a smaller container is that its a bit easier to pour the right amount into the weighing cup/jug thingy, prior to pouring them into the grinder.

Same here except I keep my beans in the freezer and it takes me about 30 seconds to open the bag measure out the amount I want and re-seal it and pop it back in the freezer.
