Both actually. I've taken readings and adjusted for temp and I've waited until it gets down to the calibrated temp of 60F. Same number.

I was just hoping you would catch something I didn't. I'm gonna try the formula that ALLEY suggested. Thanks for all the help. I appreciate it.

I'll try the formula. I've actually measured out that kettle 3 times using different measuring quarts. Believe me, no one is more frustrated than me. I really appreciate all the help. Thanks again for taking the time. Cheers.

I agree with you that there is no other explanation. Both pre boil and post boil wort is thoroughly stirred. My measuring stick was calibrated by pouring one quart of water into the kettle and making a hash mark. I did this one quart at a time up to 7.5 gallons. My hydrometer has been...

Right there is the problem. My post boil volume reading is 5.25 gal. It's a 2 gal / hour boil off. Very high. But, I do have 15 gal kettles with a lot of surface area. It's the MoreBeer Tippy System (http://morebeer.com/category/morebeer-tippydump-sculptures.html). I do not use a hop bag...

Boil rate is always the same. 2 gal for 60min. I always keep a rolling boil. Here is an example. Last week I made a stout. My pre boil gravity/volume was 1054/7.25. Post boil was 1064/5.25. Now, if you do the math and convert this to gravity points we get: (54 x 7.25) = 391.5. 391.5/5.25...

The hop absorption really isn't a factor in my system. There is literally nothing left behind as I use a pump to transfer from the boil kettle to the fermenter. I use pellet hops and no bag. The particulates are so fine they go right through the sifter. There is no dead space in my kettle...

I keep a rolling boil. Nothing crazy. My kettles have a lot of surface area, so I always have a 2 gal/hour boil off. My mash efficiency varies depending on the grain bill, but I'm usually close. For this particular batch my pre boil gravity was 1045 with 7.25 gal. Post boil vol was 5.25...

I do. I use three actually. Beer Alchemy, Beer Smith and Beer Tools. Primarily Beer Alchemy though. They all use the simple equation to determine your OG from pre boil gravity and pre and post boil volumes. For me it's always 7.25 gal pre boil and 5.25 gal post boil in 60min. Boil off of 2...

I have two hydrometers and a refractometer which are all calibrated correctly using distilled water and correct temps. I'm lost brother. Nobody can seem to answer this for me. I forgot to mention that I stir it very well, so it's not a false reading either.

Hey guys. Read your post. I'm having the exact same issue and can't figure it out either. By your post, it sounds like you're an accomplished brewer. I use a more beer tippy system and it sounds like you are too. My OG is always 10 pts lower than what it should be if you do the math like...

I agree, the laws of physics do apply. I'm not reading anything wrong. Post boil volume is 5.33 gal. 5.25 is transfered. I double checked all my readings with both a hydrometer and a refractometer. My volume readings are also correct. I just don't get it.

FG should be about 1015. The 1070 and 1060 aren't my real numbers. I was just trying to make this easy. Real #s are: pre boil 1045, OG 1056. With Target Pre-Boil Gravity: 1.051 Actual Pre-Boil Gravity: 1.045 Target OG: 1.069 Actual OG: 1.056 Target FG: 1.015...

Gents, Need some help on this. I'm an all grain brewer using a MoreBeer Tippy system. My boil off is 2 gallons for 60min (high, I know). It's a rolling boil. Pre boil gravity is almost always spot on. Let's say 1050 for this example. I boil off 2 gallons and every single brewing program...
