My first white wine has a fizziness and tasted like it is almost carbonated. Do you have any suggestions?

Are the lumbrusca riparia grapes I’m growing the same kind of grapes used to make lambrusco wine?

I added oak beans to several different batches of wine at the same time. Only my Chardonnay turned milky and hazy while the other wines were clear. Do you have any idea what happened?

My wine has developed a foul taste and odor from Brettanomyces. Is it correctable?

How is Fume Blanc made? I would like to make some at home!

I picked up two very old glass carboys at a flea market and I don’t know what used to be stored in them. Should I still use them for winemaking?

Would a welding supply company be a good source of argon gas for winemaking?

Commercial wineries get a lot of their argon from welding supply houses, so there’s no reason you shouldn’t, too. The only thing that I would wonder is just how much argon you’ll


I just bought my first barrel and opted for a paraffin-lined model. Will this work or do I need charred barrels for wine aging?

When I opened my blueberry-Zinfandel wine I was struck by a strong acetone-type smell. Am I experiencing bottle sickness or TCA?

A sediment like fine sand is appearing in my homemade wine after it is opened. Can you tell me what’s going on?
