Yeast Cross-Contamination

[Vegan Thor]

Hi folks,

I have a Session Mead fermenting in a cupboard with a heat mat, and have just added a Sourdough Starter to the same space.

The Sourdough Starter appears to be VERY active.

Is there a problem with keeping the two of them in the same cupboard?
I have an airlock on the mead, so the contamination would only be happening one-way (hopefully).

TIA!

I wouldn't.

That mead is far too close to a real source of lactobacillus
