00:00i'm martin keane from the homebrew
00:02challenge and i'm martin keane from keen
00:08and today i'm brewing a stout
00:11let's make it a coffee stout and to make
00:14it more interesting i'm going to roast
00:17in this popcorn maker
00:34now the way i'm going to start off
00:36making a coffee stout is just to
00:38make a regular stout
00:41my grains right here
00:43thank you atlantic bruce pie crushing
00:45them up measuring them out
00:48oh already smelling good
00:51so let's get these mashed in the uh
00:54temperature i'm going to mash this at is
00:55152 fahrenheit that's 67 celsius
00:59okay so yeah very standard mesh for this
01:02one i'm gonna run it for probably about
01:19now like so many additions when it comes
01:22to beer there are many ways that you can
01:25into your beer you could add it right in
01:28at the mash bit like i did with my
01:31pumpkin beer you can add it into the
01:34boil and you can add it into the
01:37prior to peach pitching the yeast or
01:40after the use of finished working
01:43as for what coffee to add well there are
01:46a lot of options for that as well so you
01:51brew a regular old cup of joe and throw
01:55the point to keep in mind there is that
01:58coffee does have oils in it and those
02:02oils will start to affect head retention
02:04a little bit and also keep in mind that
02:08well coffee is often quite bitter so you
02:10might want to cut back the amount of
02:12hops you're adding at the bittering
02:13stage to account for that
02:16another option which i think would be a
02:18really good one is to use cold brew
02:20coffee cold brew coffee generally is a
02:23little smoother it has much less
02:25bitterness and would be a great addition
02:27into the beer to create cold brew coffee
02:30you just simply steep coffee beans that
02:32are coarsely ground into water at room
02:36temperature for typically 16 to 18 hours
02:39then you could take that and add it in
02:44then you could just kind of cheat and
02:46you could use a coffee extract
02:49things like this coffee concentrate
02:51provide a pretty smooth tasting coffee
02:55again very little bitterness and you can
02:57just add this into the fermenter or even
03:00just take a drop or two and put it
03:01straight into a pint of beer
03:04but what method am i going to use today
03:06well i am going to be adding my coffee
03:09at the very end of fermentation during
03:13and i'm going to be throwing in a
03:15regular old cup of joe
03:24the recipe for today's beer is really
03:26based on an american stout so using
03:29primarily american ingredients and just
03:32a little bit more on the hot side than
03:34you would add in say a dry irish stout
03:36so looking for building a beer here
03:39around sort of 10 62 around 6.3 percent
03:44the main base mount that i'm using in
03:47fact the only base malt is two row and
03:49that's at 68 percent and then i'm adding
03:52three specialty malts each at eight
03:54percent that's munich malt a chocolate
03:58malt and then caramel 60
04:00and then like any good self-respecting
04:03snout very important we have these two
04:05additional ingredients
04:06flaked barley and roasted barley both at
04:20now i'm going for an ibu here of around
04:2247 just from the hops not from the
04:24coffee and i'm gonna get that by using
04:26as my bittering heart magnum this is
04:28going to go in at the start of the boil
04:30nice clean bittering hop and then at 10
04:33minutes and 0 minutes that is when i'll
04:35be heading in the cascade
04:41those things in my way um
04:4510 56 wise to 1056 american ale is what
04:49i'm using gonna be fermenting at 68
04:51fahrenheit 20 celsius i'm gonna let
04:54fermentation run its course
04:57and when i get to the cold crash stage
05:01that's when we'll revisit adding coffee
05:23been a month the beer is
05:25well and truly fermented out at this
05:27stage and cold crushed as well
05:30now it's time to add the coffee
05:35coffee that i roasted myself using a
05:52i'm going to brew some coffee from these
05:56get it into the beer now as for the
05:59amount of coffee to add if you were
06:00brewing a five gallon batch then i would
06:02be adding in 600 milliliters of brewed
06:08um and i like to use a 16 to 1 ratio for
06:12my water to coffee beans so 16 parts
06:17one part coffee i've brewed a three
06:20gallon batch so i'm going to add in 320
06:23milliliters of coffee which works out at
06:26a 16 to 1 ratio of 20 grams
07:07and given that the beer is already ready
07:10i figure i'm just going to put this
07:12coffee straight into the keg and then
07:16wrap the beer on top
07:29well if i'm tasting coffee style i need
07:33you are a coffee guy i like coffee too
07:35just as much as beer and thanks for
07:37having me back yeah appreciate it
07:38pleasure to have you back okay so
07:43super curious to see how this one's
07:44going you did a pour over a porn right
07:47yeah and then you put
07:49the resulting coffee in the keg and then
07:52transfer the beer on top of it that's it
07:55let's give it a smell yeah
07:58definitely smelled the uh the roasted
08:03color's great nice and dark it looks the
08:06pot yeah i want to get into it yeah
08:08let's get into it cheers
08:12yeah there's a coffee
08:14yeah yeah but it's not over the top yeah
08:16it's on the back end yeah the coffee on
08:19swallow and then it's like oh yeah
08:20there's coffee in there yeah that's
08:23one thing i was concerned about was uh
08:25how much bitterness i'd be adding in
08:28uh we were talking a bit earlier and you
08:29were saying you'd like to actually steep
08:32your coffee beans in the keg which is
08:34more of a sort of a cold brew kind of
08:36approach it's kind of the way i do it is
08:38uh i mean you always
08:40leave it in longer so i put the whole
08:44uh in a muslin bag and put in the keg
08:47and then just taste it
08:5214 16 hours and then
08:54pull the bag when i feel like it has
08:56enough coffee yeah that's that's a nice
08:58way to do it um so i was concerned that
09:02putting in you know just a cup of coffee
09:05that i would be contributing more
09:06bitterness than i intended but actually
09:08i'm not getting any sort of no it's
09:10not really bitter so if it wasn't
09:12entirely obvious do you have this coffee
09:14keen on coffee so if you want to see how
09:16i did roast these beans check out that
09:19channel i have the whole video there of
09:20how i attempted to use that popcorn
09:23maker to roast the beans but thank you
09:25very much for trying this yeah thanks
09:27for having me cheers
