Chewy Wine???

You've may have heard of a wine being "chewy"? Chewy refers to a wine that's rich, dense and full-bodied, so much so it feels like there's something to chew! You may have also purchased an unfiltered wine. Sometimes an unfiltered wine (even a filtered wine) will have some purple "sand" at the bottom of a bottle (ground up seeds, stems, etc). I personally enjoy the sand, I think it tastes like granulated sweet tarts! But have you ever encountered a chunk of grape in your wine? This happened to me last weekend. I was enjoying a nice Shiraz when, bam, I was quite literally chewing on the wine. I know what you're thinking, perhaps it was a left over from dinner stuck in my teeth. I assure you readers, this was not the case!
This might turn off the staunch connoisseur, but I have to say I enjoyed the experience. I also enjoy heavy pulp orange juice, if that says anything. To all the wine makers out there, perhaps I'm on to something, why shouldn't the occasional wine have some texture as well?
