In order to make best use of postage costs I'm looking to start ordering enough grain and hops for my next three brews every time I place an order. It means I need to know in advance what I want to make but that's fine. I'm just wondering about the ingredients deteriorating before I get to use them. I freeze the hops so that shouldn't be a problem but it does mean that the third batch I do will use grain that was crushed some 6 or 7 weeks ago. Do you think this will be ok?
