Buy one of these: Refractometer w/ ATC

Can measure wort gravity without cooling and only takes 2 drops! I measure the gravity of my runnings as i batch sparge. HIGHLY recommend this tool!

+1 to getting a refractometer! Just keep your hydrometer because post fermentation the alcohol can affect the refractometer.

Yes, you can adjust for temperature.

I usually take SG readings for my Mash output and batch sparge output. Then the pre-boil SG is:
((Mash SG * Mash volume) + (Batch Sparge SG * Batch Sparge Volume))/ (Mash Volume + Batch Sparge Volume).

I do this because then I know before I add the sparge liquid to my mash liquid both whether I am hitting my estimated pre-boil volume and whether I am hitting my estimated pre-boil SG. I can adjust how much of the 2nd runnings (the batch sparge liquid) down (if low on pre-boil SG) or up (by adding water or doing an additional batch sparge).

Was your pre-boil volume on target? (Either that was low or your boil off was longer or higher than expected.)

Yeah, forgot to mention that. Only good for per-fermentation wort. But its awesome to measure gravity of your mash too!

The refractometers are nice because you can take a sample in hte pipet from your boil and it takes just a few moments to cool down to room temp. However I have noticed my refractometer needs recalibrating now and then, so I tend to only really trust my hydrometer (but it is good ball parking tool).

I used to take readings all the way through the brew process, but I seemed to hit my numbers so consistently as I have dialed my system in, so I only check o.g. as I add to fermenter and F.G. now.

drocu, - key to your mash will always be stable mash temp. Wrap your MT in towels or other insulation like material to keep your gravity constant and not sliding more than a degree. reheat at 30 minutes if needed. Get a good thermometer

Also try to mash with a thinner 50/50 mash/sparge ratio. That is, using about half of your water needs in your mash so you can mash, then batch sparge once for the remainder of your preboil needs.

Also - you might want to adjust your future batches to 5.5 gallons if you can. With AG there tends to be a good about of hotbreak and coldbreak along with yeast, etc. in the fermenter. If you shoot for 5.5G batches your yield will be about 5 gallons less all that trub. This is why I do 11G batches (so I end up with two full 5G kegs). YMMV


unrelated but - wired up my temp control for my ale double demi fermentation chamber this weekend. Also sealed in the top and need to move some stuff so I can move on the the final stage of sealing up the chamber.

Cut up a bunch of the steel for my brew stand!! hopefully welding it up this weekend

Not that I've been doing this all that long, but that's what I like about SW like BeerSmith, you just plug in how much you want in the end along with things like trub loss, etc. and it calculates the needed volumes along the way.

Yeah I keep a jug of distilled water around and recal it every few batches. Only takes 2 seconds.

I have been using refractometers long enough to know that the slightest bump can throw them off. That being said I calibrate both of mine each time I use them. Are there any other salt water aquarium keepers here?

+ 1 to beersmith. I think if there is one thing that will allow you to become more consistent and make better beer that has nothing to do with malt or hops... get brewing software. helps you track your stuff and dial in your system and repeat your brew results. Before I got BS, I just through in the hops in even amounts, never checked the AA%'s etc. I still made good brew but the batches were slightly different. Now I always balance the hop additions based on AA%'s and can get pretty darn close with repeating the flavors, and the entire process in general. It made me pay attention to the details.

Didn't even know that brewsmith had that feature!
