Yeast Question.....

[shadz78]

So, I had to put my mead making on hold for the past, almost 2 years. Now that I've just made my first batch in the new home, I have a question about yeast. The yeast I bought (almost 2 years ago) expired in June. I just used it to make a batch. It seems to have started OK, pressure building up. Just wondering if there is something I should be watching for to see if this goes sideways or not. I'm assuming that yeast expired by 2 months isn't really a big deal, but I'm sure if I don't use it soon I'll just have to buy more. It is Lalvin 71B. TIA!

It should be fine, give it the usual nutrients and enjoy. I’ve used properly stored dry yeast expired 1+ years and it’s been fine.

Dry yeast is dormant and is not dead or inert. Stored at 75F, a dry yeast will lose ~20% viability per year. Stored at 38F it only loses ~4% per year

Thanks Guys! It's been in the refrigerator since I bought it. Thanks Again!

I started new 4.2 gallons batch 11 days ago using D47. The yeast expired in June but it's working it's way nicely....
