M F Scotch all grain.

Postby RaymieDubbs » Mon Jan 08, 2018 4:28 pm

Ran my first scotch AG mash last night. I use two pots, 2.5 gallons in each to heat to strike temp. I went to just over 160F. I use a 10 gallon rubbermaid drink cooler and brew in a bag method. After dumping the strike water and adding the grain my temps dropped to 145F lower than I had hoped so I heated my extra gallon of sparge water to around 165F and dumped it straight in instead of waiting till the end to bring my temps back up. Hindsight, I will warm up my cooler next time before adding the strike water. It was room temp and I'm pretty sure that's what dropped my temp so fast. I closed the lid and let sit for two hours, stirring the grain and agitating bag, kind of like a giant tea bag every 20 minutes. I finished up with exactly 5 gallons of wort clocking in at 1.060 OG. Racked into a no chill cube and I will pitch whiskey yeast tonight. I was surprised that 6 gallons of water only got me 5 gallons of wort, even after letting the bag drain as well as squeezing it out.

Condensed version:
5lbs Peated malt
7lbs Maris Otter
5 Gallons strike water shooting for around 155F after grain addition
1 Gallon sparge water @ 160 used to flood sparge at the end
Ended with 5 gallons @ 1.060 OG
Racked into no chill cube for later fermentation.

Sounds like you did good! Let us know how it turns out, not a scotch fan, but planning to make some eventually for friends.

It actually turned out terrible. I just dumped it last night haha. So I think I wen't wrong in two areas. One was I bought bulk grain from my local home brew store. The clerk even said something about not many people buying the peated malt so who knows how old it was. I also asked him for "Whiskey yeast" and he handed me ferm fast whiskey yeast. I should have just ordered fresh malt and used the standard bread yeast, tried and true. It was a bummer because I could tell a decent scotch was in there but there were just some terrible off flavors.

Why did you dump it?

I made a scotch last year that wasn't too far off from the recipe you used. It definitely needs TIME. It's been over a year now and it's just now starting to come around.

Yeah man never dump it. I was gonna dump 2 quarts once, sure glad I didn't they are great now. All else fails run it through again.

+ 1 BayouShine... RaymieDubbs, You could have posted a question before the tossed it. Your talking about a bad smelling and tasting white dog. It needs time on some good charred oak.
I'll just sit quietly in the corner over here, with a tall glass of something special.

Maybe I did mess up. I've done mostly sugar heads so this was new to me. There was also a gray ring in the boiler after the run, looked kind of like a krausen ring. I just didn't feel right about it. Next time I'll save it no matter what.

That funky ring was most probably a result from the protein break when your wash came to a boil. A mess for sure, but nothing to panic over.

you'll get that, it's the foam from the beer.
best fix for this is not to look in the boiler after the run

Well I'm no quitter so we will go for try number two soon. I can't promise I won't look into the boiler though.
