[quote=“selair”]Here is what I managed to pull together after many a try. She is a thing of beauty!
As far as the infected wort addition at the end, it is a must for this recipe. The details are below. Just take about 1/2L of Guinness (1 tall can). Mix in about an ounce of grain to it in a container. Cover it in a nice warm place out of the light and let sit for about 1 week. You can do this after you brew the beer. You add the soured beer before bottling/kegging. Before you add it, strain out all of the solids that you can. It stinks to high hell, and I was more than skeptical when I first tried it. Then boil just the beer for fifteen minutes. This kills everything. Then add it to the fermented beer and bottle/keg. It gives the distinctive twang of Guinness. It is the biggest leap of faith you will take in brewing beer to throw that in there…but it is worth it.

Carbonation and Storage
Notes
Ferment at 62 degrees for 14 days to allow for dryness to develop. Higher temps cause sweetness and fruitiness. Add soured stout (1.5L Guinness allowed to infect with a handful of grain for 2 weeks, strained then boiled for 10-15 mins) after fermentation is complete along with a pack of gelatin and polyclar. Gleatin and polyclar make the beer clear so that nitrogen diffusion plate does not clog. Allow to sit for one week. Carbonate to 1.9 volumes with co2, then put on Nitrogen at 19 psi.
Voila! Guinness.
