Hello homebrewers of the world,

I am using the BeerSmith tool for my home brewing. Three IPA brewing sessions went fine, now I got a problem with my fourth session.

I tried to brew a Porter and, yes, we made some mistakes but nothing serious. We reached the OG of 9.5 Plato and the FG should be 3 Plato. It has been fermenting for 5 weeks now and it still stays at 5 Plato (since two weeks now).

Two days ago I added an additional 100ml Edinburgh Scottish Ale yeast (as used in the original recipe) and added 35 gr. Magnum hops for dry-hopping. I rised the temperature in the basement from 20 to 24 degrees (Centigrade) ... nothing happens, still 5 Plato ...

I have also attached brew steps.

Any ideas? Your help and support is very much appreciated ...

Best regards from Frankfurt/Germany,

The Nuns Court Brewer

...if the final gravity hasn't moved for that long it's done if it bad been a stuck ferment it would have went away after adding more yeast

Are you measuring your Final Gravity with a hydrometer or a refractometer.  If using a refractometer, then you must make a correction for the alcohol content.  You can do this using the refractometer tool in BeerSmith.

Guten Tag, Greetings from Mannheim :)
Could it be that your mashing Profile produced to much of unfermentable Sugars? probably you know that higher mashing temperatures will result in high molecular weight Sugars.
i hope it helps
