🧪 Material Safety & Leaching
- Stainless Steel Construction: High-quality stainless steel (like Stanley's 18/8 grade) is non-reactive and BPA-free, meaning it won't leach harmful chemicals such as BPA or phthalates into your coffee.
- Heavy Metals Risk: Poorly made stainless steel could leach trace nickel or chromium, but reputable brands like Stanley use food-grade steel that meets FDA/NSF standards.
- Plastic-Free Brewing Path: Unlike cheaper coffee makers, Stanley avoids plastic reservoirs or tubing, eliminating risks of hormone-disrupting chemicals.

☕ Brewing-Related Health Concerns
- Cafestol & Kahweol (Coffee Oils): Mesh filters allow these compounds to pass into your cup. They can raise LDL cholesterol if consumed daily in large amounts.
- High Caffeine Load: French press immersion extracts more caffeine than drip or pour-over. Excess caffeine can cause jitters, insomnia, and elevated blood pressure.
- Acidity: French press coffee tends to be more acidic, which may aggravate acid reflux or stomach sensitivity.
- Sediment: Tiny particles add body but may irritate digestion for sensitive individuals.

📊 Risk & Safety Dashboard (Trait Flags)
| Trait Flag | Stanley French Press |
|------------------------|----------------------|
| 🛡️ Material Safety | ✅ Food-grade stainless steel, BPA-free |
| ⚠️ Heavy Metal Risk | ⚪ Minimal (trace nickel/chromium possible, but within safe limits) |
| 🧪 Chemical Leaching | ✅ None from steel; avoids plastics |
| 💧 Coffee Oils (Cafestol)| 🔴 Present → may raise cholesterol |
| ⚡ High Caffeine | 🟡 Medium–High (immersion extraction) |
| 🔥 Acidity | 🟡 Medium (can irritate reflux) |

✅ Best Practices for Safe Use
- Moderation: Limit unfiltered French press coffee to a few cups per week if cholesterol is a concern.
- Alternate Brewing: Use paper-filtered methods (drip, pour-over) to reduce cafestol intake.
- Maintenance: Regularly clean with vinegar/water to prevent mineral buildup and bacterial growth.
- Water Choice: Use filtered water to avoid scaling and improve taste.

Bottom line: The Stanley French Press itself is safe and non-toxic, with no meaningful leaching risks thanks to stainless steel construction. The health concerns come from the French press brewing style (cholesterol-raising oils, caffeine, acidity), not from the materials.
