A Russian Imperial Stout following the 8 Wired iStout recipe which came directly from the brewer. Soren Eriksson gave the full recipe specs on The Brewing Network’s ‘Can You Brew It’ podcast (3 Jan 2011). I used a can of light malt extract to provide some of the fermentables and keep my grain bill to a reasonable 8kg. Also worked out really well using some of it as a starter to build up the yeast count from a single packet of US-05. Original gravity came in a little lower (harder to get the usual efficiency with the bigger, higher gravity brews), but still had a pretty decent OG of 1.098. The unhopped wort tasted delicious! Did no-chill (overnight cool in sealed vessel). Poring it into the fermenter next morning, it had a look and consistency of thick black oil, so I’m calling it ‘Black Gold’. The beer tasted great at bottling. My biggest beer brewed to date!
