What if I had a friend who measured the amount of his wort after the mash tun wrong, and I ( I mean he) at 7 gallons after a 60 min boil. Could he just reduce that to around 6 gallons and check the SG?Man I am truly a messup today.

So what's the volume and gravity right now? 7 gallons @ 1.038?

What is the gravity for your "friends" 6 gallons? Assume that after the 60 minute boil, your "friends" gravity reading was acceptable, I would tell your "friend" to put all 6 gallons in the fermenter, but to use that blow-off tube. If your "friend" was so inclined, he could can 4 quarts in a pressure canner to use for starters.But... I would just put it all in the fermenter. Tell your "friend" that if he kegs, he will have to also bottle at least a 6 pack (since it all won't fit in a keg) and send it to Deerslyr.

Refractometer reads 1.038 with 6.5 gallons of wort. Shall I reduce it down and look again at 5.5 gallons

At 5.5 gallons you'll have a gravity of (38 * 6.5) / 5.5 = 45 -> 1.045.

And Fermcap of course!

I ran it through a caluclator. Should adjust to 1.037. Nominal change from what we expected based on the initial data he gave us with respect to the gravity.

It would get you closer to where you needed to be and makes a lot more sense.

In other words, I will be within striking zone for the OG of 1.048 that KenLenard recommends.

You'll be at 1.045, as I said earlier.

[Deerslyr]

At 5.5 gallons you'll have a gravity of (38 * 6.5) / 5.5 = 45 -> 1.045.

I think, with this "adjustment", that he actually came a lot closer to hitting his targets than he realized. Over-sparged for too much boil volume. I don't know what the hops additions are like, but he may just want to put it in the 6 gallons at 1.038 so as not to throw off the hops profile. Do you agree? At most, maybe another 30 minutes of very vigorous boil for a 90 minute boil. Shouldn't affect it too much... unless he already used his aroma hops.

[Deerslyr]

Apologies... when I pasted in that calculator, I didn't realize the values weren't coming through. I was coming up with the same 1.045 that Mtn came up with. He just knows his math. I'm stupid without the intertubes.Mtn... what is your assessment on the hops situation?

[MtnBrewer]

Mtn... what is your assessment on the hops situation?

No math involved. Just straight arithmetic. :)I was wondering about the hops too. JD have you added the finishing hops yet? If so, do you have more to add at the end of the boil? What was the original hop schedule? (Sorry if all these questions have been answered and I missed them.)

[Deerslyr]

This might be where he has an issue this go around. If he already added them, then he should just go to the fermenter. Then he should go back to the software and run the session with his actual volumes and readings. I'm guessing it will be a good tasting, low gravity beer... perfect for consuming mass quantities a hot, humid day.

I have to say that this hasn't been fun at all.

The hardest part of AG brewing is learning that it is not very difficult.It is easier than all the books, how to post, FAQs, etc make it seem. Especially if you are doing the Denny batch sparge method.1- Put grain in the mashtun2- Put hot water in the mashtun3- Stir it up4- Wait5- Stir it again6- Add more water (this step might be optional)7- Voulaf8- Drain wort9- Add more water10- Wait11- Drain wortAll of those steps are very easy. The only tricky one is Step #2. How much water and at what temp. That one, Jethro, you have to do some ciphering. Even #2 is not hard, once you dial into the fact that your mashtun absorbs heat, then it is easy..

Unfortunately the hops is gone. 1.5 oz of MT Hood. Damn! Guess this beer will be pretty sweet.I just had .5 ounces that I just added. There is nothing left.

What were your Alpha Acid's on those Mt. Hood's? If you added them at 60 mins, you'll have more bitter beer than you planned. Especially since you're OG is off...

Fixed for me

I would have thought he would be underhopped, if anything. Mt. Hood comes in the low 4% range. Wish I had my software here at work to see what the IBU differences would be.

But if he added his finishing hops and then boiled for another hour, it would be too bitter, no?
