Hi all
I'm Gilles from Belgium, Antwerp, and I've been homebrewing for a year. After reading John Palmer's book, I've started creating my own recipes. So far so good, especially with the help from Beersmith (awesome piece of software!) except for 1 problem: I always miss my Est Original Gravity by quite a few points !
Yesterday, I brewed an American style IPA with Citra & Cascade hops and missed the OG by 8 points (1056 instead of 1064).
Can someone determine the issue? I've attached a screenshot of my equipment profile.
Some extra information:
Lot's of missing data, I know, but I'm trying to measure more and more data so complete the puzzle. Not sure how to measure the loss in the mash tun though?
Here's the recipe of my IPA

Some extra information:
- I always brew small bathces of 5 liters (bottled) or 1.3 galon because I drink on my own and have limited space available
- I use a Bulldog malt mill
- Unfortunately no pre-boil gravity measurement
- I use a calibrated refractometer and use Beersmith to convert Brix to gravity
- After transferring from primary fermenter to secondary I lose about 300ml (0,07 gallon) of stuff. Then from secondary fermenter to the bottle I loose another 100ml (0,03 gallon)
- I use a large mash tun (cooler) for mashing with a "bazooka" at the bottom. Not sure how much is left after transferring to the boiling kettle
Lot's of missing data, I know, but I'm trying to measure more and more data so complete the puzzle. Not sure how to measure the loss in the mash tun though?
