I am going to try my first all grain batch this weekend and I may have already screwed it up. When buying the grains, mixed them all together, then after looking at the recipe, I realized that I was supposed to mash the dark grains for the last 45 minutes versus the 75 minutes for the rest of them. I asked the LHBS where I bought the grains and he said it would probably make it a bit more bitter. The recipe is for a chocolate coffee sweet stout. Should I go ahead and make this as mixed or should I not waste the hops/yeast on it? I know it will end up being beer but if it is going to taste like crap I would rather just get another batch of grains.

The recipe is from tastybrew and I am adding 16 oz of brewed coffee for the last 10 minutes of the boil -

Make it, then make another batch in a week or two, then in a couple months, taste them both and see which you like better. That way you will also be able to tell the difference in taste and will be able to make adjustments in future recipies.

Definitely don't worry. I'm having trouble understanding how the extra 30 minutes is going to have a negative effect on the dark malts. I've never mashed one grain differently than the other in any beer I've ever made.

Maybe I learn something new here today.

definitely DO NOT waste your time on that batch. Let me know if you still you still have the grain. I can PM you my address, and you can send it to me. I'll make sure It is disposed of safely.

Just brew it.

I've talked with a few who only stick in specialty grains the last 15 minutes. Supposed to make the beer more clear. I'm thinking about trying it just to see. I'm curious how it might effect the pH. Also with beers that are dark to begin with I'm not sure why it would matter.

OK - so it looks like the advice is to go ahead and make it or send the 11.5 pounds of grain to some guy in Iowa. I guess I'll make it!

I have never not had my grains mixed before mashing, that's the way every HBS has shipped it to me (mostly BrewmastersWarehouse) as they mix them together before milling then packaging.

I never heard of mashing some of the grains for only part of the mash time. Actually, I would think that adding a bunch of grain late in the mash would mess up both your mash temperature and potentially your mash pH. You should be totally fine mashing them all at the same time.

This is my first use of my new 10 gallon MLT as well. We'll see how it goes.
