Some day in the not-too-distant future, I want to make wine. But I don’t want to ruin perfectly good grapes.

So I’m training myself on bread. Sourdough bread, specifically. This spring, I’ve been nurturing a sourdough culture: lactic-acid bacteria and yeast, feeding and reproducing on wheat flour and water. What’s growing looks like gluey carbonated yogurt.

Aptly called starter.

The bread-making process isn’t unlike the wine-making process. Both grapes and wheat undergo chemical changes as bacteria and yeast reproduce, causing fermentation, alcohol and gas production, and the tasty conversion of acids.

To be honest, I started messing with sourdough because friends were baking it. I enjoy gnawing on a tangy bit of bread while I slurp fermented red. So, yum! Sourdough pairs with cabs. With merlot and sangiovese and barbera and aglianico.

A few great pairings:

• An earthy mourvèdre with sourdough and baked brie, drizzled with honey and garnished with pears.

• A jammy zinfandel with sourdough toast smeared with herbed butter.

• A syrah with sourdough crackers, baked with sea salt and flecks of black pepper.

Let the mouths water.

Pairings aside, I’m getting evangelical about the chemistry of sourdough and its health benefits for my intestines, waistline and mood. As I write this, Pharrell Williams’ “Happy” is looping in my brain.

I’ve been calling my sourdough starter yeast. And, yes, the starter has some of the single-cell fungi that make bread rise. But in most sourdough starters, lactic acid bacteria outnumber yeast by about 100 to 1. I love the names of these bacteria—Leuconostoc, Pediococcus, Weissella. And most prevalent, you know her and you love her: Give it up for the multi-talented Lactobacillus sanfranciscensis! Though you’d think that the latter microbe must be endemic to its namesake, San Francisco, it’s been found in sourdough cultures in Belgium, Italy and Germany.

In February, Karen Dixon, who works at the Moonstone Crossing Winery in Trinidad, Calif., gave me a plastic container of gloop—a legacy sourdough starter passed from friend to wino to friend. She sent me to a website, Cultures for Health, with info on the care and feeding of starter and how to make, knead, proof and bake bread.

I’m learning so much, so fast.

Keeping starter alive requires little time—but that little time must be dedicated on a regular, rhythmic basis. To keep it active and ready to make bread, I feed it daily. Because it’s a growing community, the small starter gloop becomes a massive sticky vat kinda fast.

If you don’t want to feed an ever-expanding mass of bacteria and yeast, you can discard some. Since it pains me to slather happy, healthy gloop into the trash, I’ve found recipes for putting this “discard” to good use, making crackers, pizza crust, cinnamon rolls.

I bake. A lot.

At its simplest, sourdough bread is flour, water and gloop—with a sprinkling of sea salt. Some recipes call for milk, fat and sugar. My recipe uses none of these. It’s vegan, lactose-free, sugar-free.

Kneading dough causes the gluten to develop. A byproduct of fermentation is carbon dioxide, and the gluten holds the gas in, making bread fluffy. Because sourdough is a slow-rising bread, the developing acids make the gluten more easily digestible. Some gluten-intolerants have no problem with traditional sourdough bread.

What I’ve learned: Don’t skimp on kneading. My first loaves were tough little dough wads. Not sour. Not fluffy. A good knead takes about 20 minutes, at least. As it turns out, this is the length of a South Park episode.

My second loaves were sourdough geodes—impenetrable rocky spheres inside of which a tasty sponge-like mass resided. The loaves dried out before I baked ’em. Slicing required a chainsaw. But inside … success—springy moist crumbs with the texture of pound cake! And so mouth-puckeringly sour. I cubed this up and ate it with runny eggs for breakfast.

I’m getting better. Warmer weather means my starter is livelier and, to be honest, that makes the kneaded bread rise—double in size—too fast. It takes time for fermentation to turn the bread sour. A few loaves have tasted sweet, bland even.

Clearly, this is an art—and a healthful one. Sourdough makes me feel physically great. Why? I read, um, health journals to find out.

The acids in sourdough activate enzymes that make more nutrients available to your body. Also, studies of bread-eating folks showed lower blood glucose levels after eating sourdough white bread compared to any other bread, including whole wheat. That’s great news for me, since diabetes runs in the family. It’s also a potential weight-loss strategy. I’ve noticed if I eat a piece of sourdough toast in the morning with some protein, I don’t get the mid-morning munchies until around 1 p.m.

Bread is rising as I write at 11 p.m. on a weeknight. I’m enjoying a lovely glass of 2008 Zucca Mountain Sorprendere, a red blend, and watching the sixth season of Mad Men on Netflix. Lovely mounds of dough are rising on baking stones atop my record player and my pellet stove (which is not fired up).

I made the dough around 3 p.m. and kneaded for a half-hour. The loaves have properly doubled, and I’ve punched the dough lightly with my fists so it can rise again without globbing over the edges of the stone.

I could throw the loaves in the oven tonight and watch another episode or finish this column. For full-on sour, though, I’m going to wait. Bread for breakfast! Baked before work! I’m going to have to get up mighty early, but that’s OK.

Have I mentioned how much bread-making helps me value the work that goes into that bottle of fermented grape juice? Thank you, hard-working makers of wine. Someday, I’d like to join your ranks.
