There's nothing arduous about bread making when you use a slow rise. I make bread and pizza dough and bagels several times a week, for couple reasons: a. it's bloody cheap, b. it's damn easy for how good it is. The process is literally stir the ingredients together and put a lid on it for about a day. 8 bagels, 3 pizzas, or a nice loaf of sourdough cost about 27 cents total.

Just go down to your local library and get My Bread by Jim Lahey.

A day seems long? I’ve not noticed any appreciable difference past 3 hours.

Curious as to why you leave it this long...

"With bread risen with instant dry yeast, it will definitely resemble visual qualities of bread, but the texture and taste will not be comparable to bread that uses wild yeast." This is so wrong it drives me insane. The key thing is the length (and thus slowness) of the rise of the dough, not whether you use wild or instant yeast. Sourdough raised on a hot countertop for thirty minutes will not be nearly as good as a…

>Sourdoughs International is a family business dedicated to the resurgence of authentic sourdoughs. Authentic? Commercial yeast produces something that looks like sourdough but is completely bland and tasteless. Absolutely nothing tastes or smells anything like authentic sourdough. When you bake it with wild yeast and lactobacilli, it will taste and smell like sourdough should. There is no other way.

>The Industrial Revolution created fast rising yeasts that almost eliminated sourdough and did eliminate the lactic acid bacteria. As a result breads baked with commercial yeast have never equaled the flavor, texture and aroma of man’s first leavened bread. And never will!

That could explain the difference in taste.

Personally notice a big taste difference, but even if that wasn't there, it's cheaper since you use significantly less yeast.

While you're right that good breads can be made with both types of yeast, there are definitely flavors you wouldn't be able to achieve with instant yeast because a live starter is often a much more complex mix of microorganisms while dry & instant yeast are more homogeneous.

We make ours at night right before bed. Using a very small amount of yeast, we let it ferment/rise for 12 or so hours and then knock it down and rise for 2-3 more hours and into the oven.

Does that make much difference? In my experience, the cost of cheese is by far the biggest determining factor in overall cost.

From my calculations, it tripled to cost of a loaf (which granted wasn't overly expensive). I really have no reason to do it any quicker though since I know when I'm about to run out of bread/bagels.

This seems like an appropriate place to plug Sourdough: A Novel, by Robin Sloan (who also wrote Mr. Penumbra’s 24-Hour Bookstore). It's a really delightful read that lovingly satirizes many aspects of San Francisco's contemporary culture while telling the story of a coder turned baker who is on a mission to teach robotic arms to bake bread.
