We're having a wet and humid summer this year, and these are perfect conditions for all kinds of fungus (the vineyard is another story, but so far so good, and we'll see what happens over coming weeks... Watch this space).

Cork will naturally absorb a little bit of moisture in humid situations (and vice versa, which is why it is important to store cork sealed wines with some humidity so that the corks don't dry out). So, when we have humid weather, mould can grow on the cork. Rest assured that the mould in only on the outside of the bottle, and cannot grow through the cork to get inside. So the wine will not be affected.

All you need to do is wipe the bottle & cork clean with a damp cloth, and you're good to go!
