This is the "Homebrewing Deals" thread, not the "Practical Homebrewing Deals" thread. A 55# sack of oats is going to take some doing to make good use of. Do you have 10 brewing friends? No? Then maybe this deal is not for you! I would guess that oats in a sealed container would last some 2 years. You are still going to need some NEIPA loving buddies or a horse or two, lest you get stuck with a ridiculous amount of oats!
