The last two bags of MCI malt I got on a group buy turned out to be stale when opened. Turns out there was no inner lining in the bag so they were exposed to the elements for a good few months.
The result is slightly soft grain which makes it a little harder to grind and lower efficiency in the mash tun.
I would rather have my full efficiency so it might suit someone new to all grain that just wants to make beer.
I have two 25kg sacks. One is pale ale and the other is stout malt (ultra pale). I used about 6kg and got 60% rather than my usual 75% efficiency. Some of that drop would have also been caused by a completely full mash tun.
Free to collect in Westmeath or from my work in Blanch.
This is whole malt, not crushed so you need a mill.
