Bought an all grain kit online about 3 weeks ago. Shipping took forever so I contacted the company. They said its possible that the package had been lost so they said they would send a replacement kit. A couple of days ago I got a package and then I got another tonight (score!). Anyway, I only have one fermenter and it will be awhile before I have time to brew the second kit. Can anyone tell me how long the kit will keep(hops,crushed grains)?
