 Weight of Water

I'm about to brew my third batch (Chinook IPA) from Northern Brewer. I realized it required a 5.57 gallon boil size. Curious to know how to measure out exactly 5.57 gallons, I searched the forum and came across a thread mentioning professional breweries measure water by weight. The more I read, this approach seemed logical and most accurate.

Because I can't offer much in advise as I'm so new to brewing, I thought I would share the bench scale I found as a way to contribute for those who are interested.

This seems to be a nice scale for the price. Low profile and decent size foot print seems like it would have enough surface area to support a bucket or brew pot. The 150lb version reads with a little more accuracy than the one capable of reading 400 lbs. 150 lb read would easily weigh 5 gallons plus the weight of the brew pot.

According to the thread and some additional research my math works out to needing 46.5095 lbs of water for a 5.57 boil size. Plus the weight of the brew pot.

Anyway, I found this interesting and the ideal method for nailing boil size. The scale seems like it would be perfect for the home brewer. When I learn more about brewing, perhaps I can contribute something more useful.

First of all, Relax. Then, DWHAHB. Unless you are conducting a rigorous scientific experiment, there is no reason to be measuring your pre-boil volume to an accuracy of hundredths of gallons. You don't even know how much you will lose during the boil!

Now, if you do know from experience how much you typically lose during the boil, fine. But a printed recipe sheet is useless for telling you that.

So, RDWHAHB. Cheers!

No scientific experiment, but don't I want to get in the habit of being consistent? What if I make a great batch and want to repeat it over and over again? Regardless of yield, but for the purposes of consistent taste, wouldn't I want to know as accurately as possible my steps so I could duplicate it whenever I want as often as I want?

True but round things off, even to the nearest .5 gallons using a calibrated stick. You don't want to be lugging 50+ pounds of wort around and if you go all grain you would have to run off while the kettle sat on the scale to stop sparging at the right time.

Get close on the pre-boil volume, then boil down to your post boil gravity because that's the number that's import. Your boil time will vary based on humidity, outside air temp, pre-boil volume, etc. but when you hit that post-boil OG you are where you want to be. If you boiled off more volume to get there, note it to make adjustments in the recipe, then tweak with DME and water to get the post-boil OG and volume you want.

I believe water weighs 8lbs per gallon.

As to the more important lesson of this thread, you don't have to be overly accurate with 'the numbers' to reproduce batches that taste exactly the same.

Meanwhile, the rest of the world says 1 liter of water = 1 kilogram.
