Ferment twice as fast? Or does it throw off the taste of wine?

Just wondering, the GF picked up two packets of the same red star yeast by accident and I dont think the yeast will last long enough for our next batch in the fridge and I hate to see it go to waste
Apfelwein- 5 gallons aging
Welchs Concord- bottled
Cranberry-5 gallons in secondary

Mostly using 2 packets of yeast in 1 5 or 6 gallon batch does 2 things: increase the initial yeast population, which means the optimal colony population will be reached in about 1/2 the usual time; the effect on fermentation time with this is negligible. The 2nd thing it does is cost more money. You can increase the culture population simply by using a yeast starter, it costs about a quarter to mix one up. I always use a yeast starter.

I've used Red Star Premire Cuvee dry yeast that sat in my fridge for a whole year & had zero problems with it. As always, I used a yeast starter. A yeast starter can save you the trouble of wondering if your yeast is still viable or not; for the cost of a little sugarwater & maybe a pinch of nutrients, you know if it's still good in about 20 minutes or so. Hope you find this info useful, GF.

If it is dry yeast it will continue to be viable for more than a year if you keep it sealed and dry.
