Imperial Dry Stout – Impulse Brew

So I got this window today between 12 and 19 and I just had to brew during this time. One of the brewing ideas that I have had floating around in my head this week is an imperial dry stout… It may not be that crazy and it’s probably nothing new to the beer world. The difference from an Russian imperial stout or something similar would be the exclusion of any other malts then you use in a dry stout recipe – pale malt, roasted barley and flaked barley.

I just mashed in 16 minutes ago and I’m going with a 45 min rest since I don’t have much more time, with adjuncts I would usually do an full hour mash or more. But I think the high mashtemp (around 68°c) will help with the conversion.

I didn’t use the full 10% of roasted barley in my grain bill since I think that would be close undrinkable without 2 years of conditioning. So i reduced that with 2%…yeah, 8% is still a lot in a 1.076 beer… But I want to push the limits. You can see the whole recipe in the bottom of the page. Now some pictures.

Le Freak from Green Flash Brewing Co. just got released on systembolaget (art. 11078). It sure is a mix between american pale ale and a belgian trippel (I know they say IPA, but I wouldn’t say that). I’m not sure if I think they got the best of both worlds though.
