Please help me figure this one out. I'm still pretty new at all grain. I've done 6 beers AG. I'm hitting my OG pretty right on, but then after fermentation my beers are drying way out and finishing SUPER low.
I know it's hard without knowing my process, but what is the most likely cause? Example: My last brew OG was supposed to be 1.052 and I hit 1.050. FG was supposed to be 1.012 and mine was 1.004. Why did it finish so low?
This has happened for my last 3 brews. My buddy that knows a lot about brewing says he would bet it's a faulty thermometer. He thinks I'm missing my mash temperatures by quite a bit. Does this make sense to you?
I have definitely questioned the accuracy of my dial thermometer. I just bought a lab grade thermometer and I plan on using it for the first time this weekend.
What is the most likely cause of this problem because it has become consistent? I'm missing my FG by around 10 points each time. The beers have come out tasting good, just not finishing within style.
