Made a new batch of Zinfindel(80gals)wine two days ago Brix where at 25. I started it with Lalvin uvaferm vrb 90 g with 114g of goferm and 3oz of fermaidk.. never used the goferm or fermaidk before.. batch took off like a bat out of you know where today brixs dropped from 25 to 17 temp is at 91... too hot. Its in a controled room temp of room is 68.. seems like its smell like egg salad but think it could also smell like bead... what now... dont care to loose it.. also put a bottle of water that i froze to try and cool her down been making wine 7 yrs now havent run into this before .. any help would truly be appreciated

Ok, time for you to post in a format that we can help you with. Please post in tabular format (see example below):

20 lbs honey
4 gallons water
10 grams yeast

Your other specs seem a bit off.


Please post your recipe here and let us know what you were intending to produce.

Cheers,

Oskaar

Sorry, I misread your first post and didn't catch the specs for some reason, maybe it was because I was reading without my specs :tongue3:

I'd go ahead and give it a dose of Fermaid-K/DAP mixture at a ratio of 70% Fermaid K and 30% DAP. Generally the eggy smell tends to be nutrient starved/stessed out yeast. I've seen this in my Zins as well. No big deal if you stay on top of it. Make sure to punch down that cap several times a day and pump over if you have the equipment. You might consider delestage if you have another vessel to pump over to.

Hope that helps,

Oskaar

How far along is this wine now anyhow?

Are you past the 1/3 sugar break (30% drop in total brix) also check your TA and VA to make sure you're in the right range for what you want, and check your pH to make sure you're in a yeast friendly zone. Are you still on the fruit? If so for how long? You said you racked, so I'm guessing you're pretty much through fermentation so hold off on any dosing until you answer back on current brix, pH acid, etc. and how far along your fermentation is.

If you're still in primary, you'll want to add the nutrient at a rate of 1 gram per gallon so if you have eighty gallons you're going to go eighty grams total with 60 being Fermaid-K and 20 being DAP. You may want to go less depending on how you've been dosing to this point.

Let me know,

Oskaar

OK,

Your color extraction should be good by tomorrow, tannin extraction may take longer, that'll be up to you to adjudicate based on your preferences. I'd say that post nutrient addition the smell will go away within a day, if it doesn't let me know and we'll go through a couple of things. Make sure to keep that cap moving as much as you can. Are you using a macro bin or 55 blue barrels?

Cheers,

After you hit about 8 brix make sure to top off that second barrel with CO2 or Argon to keep the O2 from queering the wine. Just flood the barrel with it.

What's your ambient temperature there? Have you stuck the must for temperature?

Good luck,

Hold off on the argon for now, I thought you were closing in on secondary and pressing. If you're still in active fermentation you're going to be fine with the CO2 being produced. I can't stress enough to keep that cap moving and the wine moving as well to keep that temperature from climbing.

Where did you get your grapes? Take a couple of the skins from each barrel and chew them to see if the flavor (eggie) is in the skins, if so it's probably due to a last dose of sulfur while still in the fields, or maybe even in the winery at crush. A lot of times places will sulfur right in the crusher/destemmer.

Hope that helps,

Oskaar
