Can You Ferment Pasta Into Alcohol? 🍝🥃
A curious experiment from American Copper Works on starch conversion, hydrometers, and what noodles can teach us about mashing science.
Introduction
We set out to answer a wild question: Can pasta noodles be converted into fermentable sugars? Using small-to-medium macaroni, a beer/wine hydrometer, and amylase enzyme powder, we ran a controlled test to measure gravity and conversion results.
Why this matters: Understanding starch → sugar conversion helps you design better mashes and hit predictable targets — whether you’re experimenting or running your go-to copper still.
What You’ll Need
- ½ lb macaroni (or similar pasta)
- ½ gallon water (we scale linearly)
- Beer/Wine Hydrometer
- Amylase enzyme powder
- Iodine for starch testing
- Pot (induction-friendly if available)
Step 1 — Boil & Overcook the Pasta
Bring ½ gallon water to a rolling boil, add ½ lb macaroni, stir, then lower to medium. We purposely overcooked to make it completely mushy — we’re extracting starch, not making dinner.
Pro Tip: Once boiling, turn off heat and cover. Residual heat finishes the cook evenly without sticking. Old-school trick, zero scorch.
Step 2 — Iodine Starch Test
Cool a small sample and add a few drops of iodine. If it turns black/blue, starch is present. Our test confirmed plenty of starch to work with.
Step 3 — Enzyme Conversion (Amylase)
When the pasta slurry cooled to ~155°F, we added amylase enzyme and rested ~2 hours. A quick taste showed subtle sweetness — a good sign conversion was working. A repeat iodine test faded instead of turning black, indicating starch reduction.
Step 4 — Hydrometer Reading & Gravity Math
We strained out noodles, chilled the liquid to ~70°F, and used a hydrometer.
- ½ lb in ~1 gal showed about 1.014 (adjusted from 60°F calibration).
- Scaled to 1 lb/gal ≈ 1.028 (28 gravity points).
Note: Gravity points are the “.0XX” portion (e.g., 1.028 = 28 points). Use temperature corrections for accuracy.
Results & Takeaways
Can you ferment pasta? Yes. Overcooked noodles + amylase = fermentable sugars with measurable gravity. Will it taste like grain? Probably not — most distillers still prefer corn or barley for flavor, nutrients, and predictable performance.
But as a learning tool for starch conversion and cut-planning, this experiment delivers.
FAQ — Fermenting Pasta, Hydrometers & Enzymes
Can you ferment pasta into alcohol?
Yes. Overcooked pasta contains starches that can be converted into fermentable sugars using amylase enzyme. Our test produced ~1.028 SG (28 gravity points) per lb/gal after conversion.
What hydrometer reading did you get?
At ~70°F (adjusted from 60°F calibration), we measured about 1.014 for ½ lb in ~1 gallon. Doubling to 1 lb/gal yields ~1.028.
Do I need iodine to check starch conversion?
Iodine is a quick indicator. Black/blue = starch. After the enzyme rest (~155°F), the reaction should fade, indicating starch → sugar conversion. Confirm with a hydrometer and a small taste (slight sweetness).
Will pasta make a good-tasting wash?
It’s fermentable, but most distillers prefer traditional grains like corn or barley for flavor and consistency.
Is home distilling legal where I live?
Regulations vary by state/country. Always check local, state, and federal laws. This content is for educational purposes only. For equipment, see our copper stills.
