Big foam when adding Kieselsol.

[kh54s10]

When I added the Kieselsol to my Sauvignon Blanc it foamed up until I had to slow down on the degassing so the foam would not overflow. This hasn't happened in any of my previous 3 wines.

Is this normal?

Normal? Most of us like to think not. Does it happen? Yep, more than most of us would like. So I'll just say it's "sorta normal".

Most of us have had the volcano of foam at some point in our winemaking lives. I ran a Ferment on Premises for a few years, so I've had it happen a time or many.
