What you are experiencing is normal and it
should not create any problem especially
that you are keeping it wiped up.

I have made kimchi which ferments and I put
the jars in a large pot to catch the dripping.
I suspected I may have needed to leave more
head room in the jars for the fermenting to
occur but it seems to be a common thing and
once your veggies are fermented for as long
as you like, refrigerate your jars and it
will be fine.

Here is a gizmo I am considering which would
take the problem of bubbling out of the
equation as it is like a safety valve which
allows the gas to escape harmlessly.

I also have since been given a fermenting
crock and it uses a seal which creates a
little "moat" of water around the lid so in
fermenting, the bubbling escapes out but does
not allow air "in".

Let us know how your first batch goes. What
veggies did you use? I am going to get more
adventuresome. I fermented some kraut but
did it too long for me and its not crunchy,
but my kimchi has always been fabulous.

best wishes,
