Captain Jim and Myself at Spencer's Stadium Tavern for the SunKing Brewery's Inaugural Dinner.




The Beginning-


Four years ago in a beer study Ė BJCP class, long time homebrewer Jim Kirk held up a gallon jug of solid dark malt extract and asked if anyone was interested in brewing with the stuff. A year later, apparently without any takers, the extract was offered again. I told Jim that I was interested and if no one else was interested I would take it. About another year went by and we were at the SunKing Breweries inaugural dinner where Jim, his wife Kate and I sat together. The extract was discussed again and plans were made to get together and pick it up. Six months later we had failed again to make an exchange the extract. Six weeks ago we planned to meet at a beer /food event downtown but at the last minute he remember that Kateís band was to play at the State Fair at the same time. We then decided that Jim would take the 13# jug of extract to the State Fair and I would meet him there and pick it up there. The Indiana State Fair is a large event. Several missed directions, dead cell phones, hot weather, beer and exhaustion led us to opposite sides of the fair. Apparently after several hours of searching Jim lugged the jug around while riding one tram looking for me as I traveled on an opposite tram looking for him. About 10 pm I gave up and went home.


Maybe this was not meant to be!


However, after all this work Iíll be damned if I am not going to brew with this stuff.


Two days later, I called Jim and mentioned that I had a dental appointment near his home and could stop by and pick it up. He would not be home Ė but would leave it on his front porch. The next day mission was accomplished.



Jims 16 year old Extract

 A solid and mysterious blob with Crystals


The culprit-


The extract is a solid dark mass with a small amount of thick syrup on the top with large outcrops of malt- sugar crystals protruding through the syrup. No version of the LME it used to be. It looks like a big block of obsidian glass.  Jim said the extract was purchased in Pittsburg by a homebrewing  friend at a co-op 16 years ago. It has become darker with age and there appears to have been some evaporization over time. However, there are no signs of any reason to believe that it is unsafe or unfermentable.


A plan-


Jimís friend Dave's last name (donít have permission to use name yet) sounds German or Polish to Jim. Sounds Polish or Russian to me. What to do Schwartzbier, Baltic Porter or Russian Imperial Stout? Hell Ė there is twelve pounds of extract here and for a six gallon brew this was going to be big. So it was decided that it was become a RIS.



Three hours at 140F to thaw this Puppy out.




The extract was placed in a water bath at 140 F for 3 hours until it became a slush that could be added to the wort. No hop aroma. Aroma of honey and malt.


From what I had on hand I brewed an all grain recipe (see below) of six gallons and then added Jimís extract to the wort and proceeded from there. The wort has fermented actively from day 2 through 8 and then tapered off over five days. Yeast and trub have been removed twice and plan on bottling in 12 days. Beer smells wonderful.




Made an error with a premixed bag - so add 4oz. 40L, 4oz. Honey Malt and 1oz. Victory and finished off a small bag of chocolate malt so it became 5oz. Final recipe is below.
