I definitely would re-think your pre-bottling aging and fining procedures. Many wines, especially those made with fruit other than grapes, are susceptible to flocculation (a fancy term for sediment) and visible fallout.
I prefer to have as much information as I can about where my raw material is coming from, and being able to handle the actual grapes is one way to help you get there.
The great thing about Campden tablets (a convenient form of dosing in sulfur dioxide for home winemakers) is that they will inhibit the yeast and bacteria you do not want (which are
Well I like your moxie. Sometimes it takes a little thinking outside the box to really make our beverages sing, and in your case (though it would be anathema to a commercial
I’m very sorry about your vine loss. I do agree with Dr. Lockwood that you will probably lose the vines that were knocked down. You might want to really work closely with
You could also try to take your lime wine and see what other kind of fun beverages you could make with it as a mixer . . .
Maple sap is a great source of natural sugar and certainly qualifies as home winemaking material. What is less certain, as you have found out, is how much of those subtle maple
Because of their chemical composition under wine pH (acidity) and fermentation conditions it’s quite possible these color compounds won’t stay red, or in solution, very long.
It sounds to me like you possibly have a heat and/or overexposure problem there with your vines. I’ll share a little personal anecdote with you about a similar situation that I have
TCA, or the “corked” off-aroma, is caused by ambient molds interacting with a chlorine molecule of some kind, usually from domestic water supply.
Most closures are packaged pre-sanitized, usually with sulfur dioxide in the sealed bags that come from the manufacturer.
It can be wrenching for a winemaker to look at his or her bottles developing a sediment over time. Many fruits, especially those high in pectin, proteins, or phenols are especially prone
To maximize your chances of a successful in-the-bottle fermentation you need to prepare a starter culture.
I would argue that the rapidity with which the sugar is consumed (and the density is lowered) is almost as important as the level of sugar itself . . .
Good for you for thinking “outside the box” and going with a different yeast choice. I love both D80 and D254 for Syrah. D80 was isolated by the ICV in 1992 from
What you’re experiencing is the precipitation over time of all sorts of complex tannins and colored compounds.
I’ve had a similar experience — both with having to pick gapes at sub-optimal times (curse you, weather!) as well as having that rough white residue on my crush equipment. The residue,
I’m a little old school when it comes to malolactic fermentation, but it’s always served me well. There are some winemakers who try to get a jump on malolactic (ML) completion and
In my experience, doing a traditional cold stability where you chill the wine down and then filter off any precipitation won’t shift the acidity enough to notice it in the taste.
Even my “purist” winemaking friends usually aren’t opposed to doing a little egg white fining when it comes to smoothing out the rough edges on their big reds. It’s an ancient and
Most folks I talk to say that sodium bentonite and calcium bentonite are interchangeable in winemaking.
Oh dear. I fear that your wine has been contaminated not just with chlorine, but with the dreaded TCA, or tri-chloroanisole aroma defect. Also known as the “corked” aroma, TCA is the
Some of the SO2 gas created by the sulfur wick certainly will transfer into the wine as sulfur dioxide.
It’s very possible this mold bloom was caused by a change in the weather or a change in your cellar environment.
I’m with you. If I was making a Port-style wine and it was 20% alcohol and 100–150 g/L residual sugar (10–15%) I would forgo the potassium sorbate altogether. I am not a
