Im assuming by burnt you mean it tastes unpleasant?? Which is quite strange because im looking at the recipe and it isnt over the top with anything really, only around 1% choc and black so that couldnt possibly contribute burnt flavours could it?? and even the RB is in a small quantity, especially for the style...
Maybe tannins??? Its hard to say without tasting it...
Tannins ... now would they be caused by a bit of over heating when mashing? If I remember I may have left it a bit longer than 10 minutes during the mash-out, and the sparge water may have been closer to 80 than 75.
Ive allways understood 78*c to be the max temp for sparge water, but have also read it can go up to 80*c without extracting tannins, but that could be a possibility... When I first started sparging with the jug I just guessed as to the temp and sometimes it was boiling, I was definately picking up tannins as stu pointed out a slight dry acridness in a few of my beers at the time, ive since measured my sparge temp and the problem went away...
All-grain brewers are very careful not to allow wort pH to reach more than about pH 6 during sparging because tannin extraction increases with pH. In all-grain brewing wort pH typically rises during the last stages of wort collection and is one of the factors letting the brewer know that wort collection should be stopped.
Bugger .. that'll probably be about it then, I've never checked but I expect, from prior posts, that it'll be out due to the local water. I've got some papers to use for the next brew, just have to work out when to take the reading.
Yeah In the last 5 RIS I have brewed, they have all tasted good for the first 1-2 months than after that they taste like balls for 3 months for some reason? but then they come right, just tieho bro shell be right!!
Allrighty - thinking of something like a NZ Draught amberish type beer, something with a bit of malt character but still easy to drink and refreshing in the height of summer...
So bear with me, this is what im thinking, any thoughts??
66.5% Pale
15% Vienna - Im thinking maybe lower to 10%, or even remove completely??
8% CaraRed - love this stuff!!
4% CaraAmber - for subtle toasty, biscuit notes
1.5% Carafa S III - Added at the last 10mins of the mash for colour
5% Cane sugar - To thin it out a wee bit
