Default Not hitting Original Gravity #'s

Hello everyone,

I bought a brewmagic about a month ago and have been brewing like mad. I also purchased beersmith for my laptop to assist in my brewing. I have brewed four batches of beer now and none have hit the calculated OG's from beersmith. In fact, I am usually off by a tenth or more on each one. For example, I build a recipe in beersmith and it says my OG should be 1.05. I take my hydrometer reading at 60 degrees and I get 1.039. Very frustrating. It's not off by a consistent amount either. I am mashing in at the specified temps with the specified water volumes. Any thoughts? So far, all my beers are very watery and bland. Frustrated. Thanks for any feedback.

John

Sounds like you need to do some troubleshooting:

The spreadsheet there, in particular, should help you hone in your system. The obvious first thing to consider is the quality of your crush, but it could be a lot of other things too of course.

I am taking the calculated volume in beersmith and sparging at the endof my mash by running the sparge water through the grain bed with a hose that whirlpools the water from the top of the grain bed and allows it to drain through. Thank you for the responses.

I'd say check your thermometer accuracy, your grain crush, water chemistry, and sparge temps...

I'm going to ask a real dumb question, but oh well. I am mashing in with the temp and volume that beersmith calculates. I flood the water into my mash run and stir the mash enough to get the grain nice and soaked. I then start my rims system and cycle the water through the grain bed so the automated temp control can lick in the target mash temperature. Just thought I would throw that out there in case cycling the water that early was bad. That completely explains my mash process. Any thoughts on letting the mash just soak in the run before circulating the wort?

If you're fly sparging, what's your rate?

are you mashing in with the water at 152, or is the grain/water mash 152 degrees (or close) after you dump the water in and mix?

Hmm. Thats a good question. I don't know. I should keep track of the amount of time it takes to sparge the grain. Is that what you are referring too? I will track that on the next batch. Thank you.
