You may already know about these. And I'm just a bit slow
with new things, but...
Last night at a nice German restaurant our waitress brought over a
wine aerator and said pour it trough this. Wow, it really did work. At home I pour a wine backwards and forwards about 10 times between tumblers but this was better. It was Vinturi brand.
It's the same as decanting wine for a few hours but sometimes (mental health reasons) you want a glass right now, and want it tasting it's best.
