I bought some wine today, couldn’t get it opened, took away all the wrapping away at the top and there was no screw top, had a taste and was unsure if it was ok to drink.
Have you googled the wine to see whether it's one of these new fangled bottle types?
I had one recently from Aldi that was neither Cork nor screw-top. I couldn't get into the damp thing and was going to take it back, but I'm glad I googled it first.
One last possibility - some cheap bottles had a plastic stopper; not a long thing like a cork, just a short plug about 5mm long, with a flange to enable it to be pulled off the bottle, and probably covered with a foil wrap. Just possible that this came off when the foil was removed. Have you still got the foil?
Well, if we knew what wine it was we might get some ideas. Carib... can you tell us?
LadyCG might have taken recently to buying plonk from Aldi; obviously she wouldn't have known how to open a bottle sans bouchon a liege.
