Recently I've been experiencing problems with efficiency. I've been brewing for about 5-6 years on the same equipment. Up until about a year ago my efficiency was consistently between 75 and 80%, but recently it has been very unpredictable.
For example, my last two brews were a Kolsch and an Altbier, and both hit the target OG. However, I made an IPA today and was 12 points below my target! I was very careful today and made sure I hit all my numbers, batch sparged slowly, and had a constant rolling boil.
As I'm using the same the gear* and process for each mash, would I be correct in thinking that grain crush might be the issue? I use different suppliers/manufacturers for different grains so I feel that inconsistent grain crush is the culprit. Interestingly, my father-in-law has also started to experience the same problem, yet had consistent mash efficiency before hand.
*my mash tun is a converted picnic cooler with a braided hose filter.
