Depends what you make it from. If you distill eight litres of wine into about a litre brandy without removing methanol, it has the same amount of methanol than eight litres of wine did. Given the average of 150mg/l of methanol in red wine, this puts it to about 1g of methanol in that amount. That is not healthy, but you need to keep in mind ingestion of alcohol slows down the metabolism of methanol through competition and the methanol will be excreted by your kidneys instead of being metabolized.

So, just like you won't go blind from a bottle of brandy, you won't go blind from distilled wine. However, you're likely to have a serious headache the morning after.
