I had a weird one. Got covid and my taste for alcohol got ...corrupted. For the first 200ms of a sip of wine or beer it tasted normally, and then a wave of extremely bitter aftertaste would come and drown all the other tastes. It lasted a few weeks and then it fixed itself in the course of one day. It did coincide with me taking a few zinc pills as someone told me taste anomalies are sometimes caused by zinc deficiencies.
