Hello everyone
I've brewed about a dozen or so batches now. Gone from extract to BIAB to my current AG batch sparge setup in the past several months.
Looking back over my Beersmith recipe numbers for my beers, most of the time I'm missing my "post-boil" OG by a fair bit, but I seem to hit my preboil gravity targets (according to beersmith) almost every time. Usually the post-boil gravity number isn't more than a few points higher than the pre-boil readings.
Examples - the Saison I brewed last night - the estimated preboil gravity was 1.053 - I hit 1.050. The target OG was 1.066 - I hit 1.054.
The wheat beer I brewed a few months ago - preboil target was 1.042 - I hit 1.044; target OG was 1.052 - I hit 1.046.
Looking back over almost all my recipes, this seems to be the same story for most of my batches. However, sometimes I hit both numbers perfectly (this is the exception, not the rule), which confuses me further, since I haven't changed anything related to my boiling/cooling technique since day 1.
I can get into my brewing technique specifics if needed, but my question is what in general would cause this to happen? Is it something with my boil? I think I'm taking my hydrometer measurements properly (after letting my samples cool to room temp), but maybe I'm not?
My beer ends up tasting fine (great, IMO), so it's not a huge concern, but I'm curious as to the number discrepancy.
Thanks.
