I'm doing a "Munich helles"

I ended up with 7 gallons of wort after batch sparging...

@ 70 degrees my sample is saying it's 1.030 on the nose. My OG on the instructions say 1.053

8.5lbs german pilsner malt
.75 lbs german munich malt
2oz melanoidin malt

it say my batch 5 gallons but my calculations say to stop boiling at 6.8 gallons to reach 1.053... Is this right?

also it's assuming 70% efficiancy...

thanks for any help!

You need to continue boiling but you may want to decrease the strength of the boil from being rapid (to get a good hot break) to more of a simmering boil.

it calls for a 90 minute boil with the hop addition at 60 minutes

the directions were fly sparging with a beginning of 6.5 gallons.

I think I got my hot break already... Foamed up... Stirred it down (didnt have time to add my fermcap) and now it's rolling boil with no foam at all...

should I add my hops now and start my 60 minutes?

The entire boil need to be at least 90 minutes, uncovered. More if your volumes are to high.
Add the bittering hops when you have 60 minutes left in the boil.

There is no reason to boil wort without hops in it, unless you're trying to increase OG.

^ That is unless your using Pilsen Malt and driving off the precursors to DMS!

Boil for at LEAST 90 minutes.

what's the "long" version of DMS?

What?

A quick calculation would have you @ a post boil OG of 1.042 for 5 gallons if your hydro reading was right.

I meant what does DMS stand for?

I thought it was

(7gallon X 1.030) divided by 1.053 = 6.85 gallons... Is that right or am I doing it wrong?

thanks again for the help Bull!
