Gas Spit vs Charcoal Spit
Gas, charcoal and electric heat are all used in vertical-spit systems. Recent döner research found differences in PAH formation — with higher levels of certain PAH markers under charcoal and lower levels under electric heating — but the evidence does not establish that charcoal always tastes better, gas is always more consistent, or one option is universally cheaper.
| Criterion | Gas | Charcoal | Electric |
|---|---|---|---|
| Used in vertical-spit systems | Yes | Yes | Yes |
| Flavor — what does research prove? | No universal ranking | No proof it is ‘always better’ | No proof it is inferior |
| PAHs in reviewed studies | Condition-dependent; intermediate in some comparisons | Higher for some markers in recent studies | Lower in reviewed studies |
| What must be evaluated locally | Heat control, ventilation, gas rules, cost, throughput | Ventilation, fire control, fuel handling, fat drips, cost | Electrical capacity, elements, cost, throughput |
Conclusion
There is no universal winner. Equipment selection should depend on the specific appliance, throughput, heat control, ventilation, regulation, local costs and desired culinary profile. Looking only at PAH research, electric heating showed lower levels and charcoal higher levels under the tested conditions — but that is not a complete equipment decision by itself.
