I love wine and I am not going to stop drinking it within moderation. So I need to figure out how much sugar(hence fructose) that is.
There is residual sugar left in most wines. A dry wine has less that a sweet pudding wine, apparently about a ratio of 1:10. So I don’t plan to drink wines such as tokaji except in small quantities.
According to “The truth about red wine and your health” “here’s a breakdown of wine types and how much sugar they contain:
- Dry: 4 grams per liter, so it’s not sweet.
- Medium dry: 4-12 grams of sugar per liter — or about 0.5 to 2 grams per glass.
- Sweet: More than 45 grams of sugar per liter — or about 6 grams per glass or more. “
If I stick to an average of less than 40ml of alcohol per day assuming the wine to be 13% ABV then that is an average of less than 300ml per day. That would then represent
- Dry: 1.2 grams of sugar per day
- Medium Dry: 1.2-3.6 grams of sugar per day
- Sweet: 13.5 grams of sugar per day. However the most I have is half a glass with the third course which is 62.5ml which is 2.8 grams of sugar
The conclusion from that is I will stick to dry red wines. If I am indulging one day then it is better to have dry wine rather than sweet wine.
it is not that simple of course as you have to ask the question what sort of sugar is that. According to the wikipedia article “When wine ferments, glucose is fermented at a faster rate than fructose. Thus, arresting fermentation when a significant portions of the sugars have fermented gives a wine where the residual sugar consists mainly of fructose, while the use of Süssreserve will give a wine where the sweetness comes from a mixture of glucose and fructose.”
