Two possible bugs with beverages.
1.
When making wort (for beer/ale etc), the QL is capped at my skill level, which is 90.54. If I then put the wort into a wine barrel and seal it with a scrap, it becomes fermenting beer. A few days later, after I have fermented it, I unseal the barrel to find that the beer QL has dropped to 88.64. This has happened on three barrels I've tested it with so far.
The official cooking guide (https://docs.google.com/document/d/1PhEhJkjNy-jl3_L5mdaQRVzyfdS7MfAt8_iNwSaHYYE/edit) says that skill has no bearing on fermentation or distillation, so I assume there's a bug here.
2.
This guy on NFI claims his beverages give 24+ hours of affinity per sip (a sip being 0.20kg). His skill, and therefore his bev QL, appears to be considerably lower than mine. But here on SFI, my 94+ QL vodka gives about 90-100 minutes per sip. What's going on here? Looks like a bug to me.
