Making a belgian tripel, used all grain mash at 154 for an hour. boiled and hour, and chilling took about 45 minutes. i used a paint bag strainer to strain into my fermenter. there looked like a lot of sediment was in the paint bag. turns out my OG is about 1.035 where i was expecting it closer to 1.070....is this due to me removing all of that trub and crap during the strain. I'd like to know what i did wrong and what to do differently next time. maybe just use liquid extract instead would be easier. i did that last time and had perfect OG and only a little think stuff in my paint strainer....help me.
