I've made a dozen different 1 gal. batches of wine in the last year. Most turned out very good. Some I've been noticing some globs floating around in the bottles of finished aging wine. Some bottles of the same batch have little or none, and some have quite a bit of it floating around. They have been bottled in the last 4-6 months. They have been stabilized and sweetened back to about 1.005 with sugar water syrup, bulk aged for another month, then bottled. I sanitize everything, including corks, with star-san. Does anyone else ever experience this? What is it?? The wine still tastes very good, just a little less visual appeal.
