RB, I guess the simple answer is an "abundance of caution." I have always tried to minimize exposure to air and from the picture you posted, because the level of the wine is just above the "shoulder" of the carboy, you are almost at maximum exposure should something go wrong, e.g. the stopper pops out, gets bumped and loosened or the air lock dries out. In secondary fermenters and bulk aging, I try to keep the the wine level at the neck of the carboy or demijohn. You also stated your SG is at 1.005, which is nearing completion and the amount of CO2 being produced is diminishing. Air is important early in the fermentation process, but my feeling is it is not at this point in the process.@Rocky I'm interested to know why you are uncomfortable with the headspace. This is only the fifth kit I've ever done so I'm just trying to learn. I was taught by a guy at the LHBS that as long as the yeast is working the CO2 blanket protects the wine from being oxidized. I just accepted that that was true. I would like to know why it makes you uncomfortable.
Briefly, my bottom line is that it can only have no effect or hurt the wine and cannot help the wine, so why do it?
This explains everything ^^^I agree I've left head space, as long as I had positive pressure on the inside of the airlock. Then bottled or racked down, or not it's having a good seal on the bong that counts.
I believe that's a personal preference.Is that good or not good?
I made the Wild Grapes Australian Chardonnay. I followed the instructions for the full six gallons using the included french oak but the with the following additions: added enough sugar to bring SG up to 1.100, added the zest of one grapefruit, and added 1 pound of chopped golden raisins (in a mesh bag). I was a little worried when the fermenting temperature went to about 80 (summer in the South) but apparently no harm done. I let the SG and fermentation activity determine the pace of moving from step to step. Start to finish (cleared and bottled) 27 days. I suspect high temperature made things go faster. I was VERY surprised at how good it tasted immediately. Ending SG was .990 and fermentation had stopped completely so I assumed it would taste very dry. Not so. It has a fruity, very slightly sweet finish and very good body. I'm more than pleased.
I have lurked here for months and my use of grapefruit zest was due to your suggestions. I've been making cheap kits for 3 years (usually Fontana) and have never had a white wine turn out as well as this. This was my first time with grapefruit zest and raisins. Also, I had not used oak in previous white wine kits.Have you follow this thread in the past?
That was a solid plan by the way.
I understand your post and would agree except: I've been making kit wines for three years (know I'm an expert wine maker). However as a former science lab tech in past lives I know how to read a hydrometer. The SG was right, that is why I was so surprised at the taste. I like a little higher alcohol in my wines. That's why I added the extra sugar. I'm sure the raisins even raised the SG a bit above my original measured SG. The wine is NOT by any means VERY sweet. It is dry but has a slightly sweet, or maybe, smooth finish. I was just extremely surprised. It may be something about the combination of the grapefruit (zest of a whole pink grapefruit), raisins, and oak. Given the SG reading, lack of residual fermentation activity, and ease of clearing, I think all the sugar was consumed. By the way, the supplied yeast, which I used, was Lavin 1118 which has very good alcohol tolerance, so I don't think the yeast quit on me.Bill, if your measurements are correct, that wine is about 14.5% ABV which is on the very high side for a Chardonnay. If the wine tastes "very slightly sweet," I respectfully suggest that your final SG reading may be in error. A wine with an SG of 0.990 would be very, very dry, one might say arid with no detectable sweetness.
In any case, congratulations on your wine. It is great that you are so pleased with it.
