Congrats on the purchase, you have a long fun road ahead.
Personally, for myself, I will leave beans in the hopper if I know that Im going to consume them within 24 hours. If I know that wont happen, I take them back out and either keep them separate from the original bag, or if Im lazy, throw them back in with the rest. I try to avoid putting them back in as opening and closing the bag often is not good.
whatever I do however, I always clear the burrs and chute of any left over grinds as I dont want that ending up in the next drink.
