    In the vineco instructions in the passport kit, they say to add both packages directly sprinkled over the must...they provided RC212 and EC-1118. This makes absolutely no sense as I imagine the EC-1118 will Kill off the RC 212. At any rate I used just the 212...rehydrated in 36 Degrees C water for 20 minutes....not typical for me but I understand RC 212 is a little more picky. Wine is supposed to be around 14%, am I going to have issues fermenting dry? Ambient room temps are around 20C right now and fermentation is moving along nicely.

    Although I haven’t read the current instructions, in the past you inoculate with the RC212 until the gravity reaches 1.050 -1.040, then add the 1118.

    Ok so they definately do not mention that, however I was planning on doing something like this to ensure it ferments dry. I imagine I should rehydrate the yeast first as this is more delicate at this stage?

    I have never rehydrated the yeast. Just pitch it in - you’ll be fine.

    I just googled the Vineco instructions: 1.7 Sprinkle Dry Yeast on top of juice base (if your kit contains two packages of yeast, add both now).

    Not sure I would do that but add them separately. But, it’s your wine kit that you paid for. If you’re not experienced in dealing with problems, the forums are here to help.

    I wouldn’t add the EC1118. The RC212 should get you to dry no problem. Just my 2c worth.

    I've made alot of kits over two years, however only had one with a slow or stuck fermentation. I ended up adding an additional half package of yeast at SG 1.020 and everything worked fine. Yes I've made mistakes but nothing that caused me to dump anything. I also haven't played with different yeast as Ive heard it doesnt make a huge difference.

    What alcohol tolerance does RC 212 have? Also does swapping yeasts like this make any difference?

    I think it’s rated for 14% but will likely go even higher. You should google Lalvin’s yeast strain profiles. There is a reference out there that runs down their yeast and what characteristics they bring out.

    Yeah I read what the 212 does, it seems like it's what im After. My biggest concern is whether or not I need a yeast nutrient.

    You should not need a nutrient with 212 when you’re doing a kit, the manufacturer should have properly fortified your juice with nutrients. That said, it wouldn’t hurt to have some Fermaid K and O on hand just for some insurance if you start to smell H2S.
