Default Does FermCap get old?

I've been using the same 2 ozs bottle of FermCap for the past 2 years. It's almost finished. I use it for both the boil and in the fermenter, and it has worked great preventing boil-overs and blow-offs.

My last 3 beers have all come out the airlock (WLP550 - PacMan - WLP 550). This latest one I used my blow-off tube. I haven't needed a blow-off tube for a long time, and getting 3 in a row that want to crawl out of the fermenter is getting me thinking. I know Belgians tend to ignore FermCap, but the PacMan did it too.

Also, when brewing the latest beer I was concerned that it might actually boil-over. It was not as stable as normal.

I assumed that since this stuff was silicone based, there was no shelf life (despite there being a note to use within 1 year on the label).

Anyone any experience.

I don't think so. The amount sold in the bottle has lasted me over a year and a half. at 2 drops per gallon I'd say there is enough in my bottle to do a hundred gallons lol.

I used some today on 2 different batches. It worked great.

Probably redundant, but you did shake the bottle?
