It's just a matter of population growth vs. resource consumption. A given volume at a given sugar concentration can only support so many cells. If you start well below that limiting number (say...

It looks to me like you've got the fermentation process pretty well nailed. How are you set for mashing, chilling, etc? If you're happy with the control points there, I'd just go for equipment...

What a confusing mess! Sure wish I'd had the foresight to get additional Perlick 425s when I still could.

I figure my best option is to just get a couple spare picnic taps for now, and then wait...

There is certainly a saturating sugar concentration in water, but it's so high that it's not an issue for homebrewing.

Unless you sparge, adding twice the grain will not give you twice the gravity...

Far be it from me to dissuade you from doing something you enjoy, but both items seem low-priority to me with regards to critical control points.

If you pitch a fresh, saturated starter, you're...

I originally missed the split batch trick as well, and agree that is a likely culprit.

Regarding lautering time, while I always drain ASAP, I really doubt that is going to hugely affect...

Hose braid version 1.0 was about 18 inches long, and serpentined around the bottom of the cooler. It worked great a few times. but then I must have stirred the mash too vigorously, and the end of...

You don't need to rehydrate. Until you do. And after that, you'll always rehydrate. I recommend preempting the time you'll wish you did, and just always do it. It's stupid-simple anyway.

The limiting factor on generations in a fermentor is cell density, not time.

If you're pitching a decent amount of yeast, you'll get at most 6 or 7 doublings (ie, generations) per batch. Let's be...

Is baking really a good idea? Seems that would just dry and harden any remaining crud to the point where it would never come out.

Too much crystal, and not dark enough for a porter.

How about 1 pound of 75-80 L crystal, and 1/2 pound chocolate malt. Keep the biscuit (or increase to 1/2 pound). Don't go higher than 25 - 30...

Presumably this is some sort of Imperial/Baltic porter? 1.078 is way to strong for garden-variety porter.

I agree with progmac about caramel malts; 2.5 lbs seems way too much. I would use less...

I agree that the yeast is the likely culprit here. I am overly sensitive to phenolic flavors, and find them off-putting even in many commercial Belgian beers.

Sure, but a little grain material in the kettle is harmless: there's no tannin extraction at wort pH (otherwise decoction mashing would be a disaster) and any solids drop out with the hot break.

That appears to be a mash paddle. I can see how they would make that out of less heat-tolerant plastic than they would a kettle spoon.

With a more recent brown ale I was...
