In a lot of the videos on YouTube that I've been watching, I noticed that in many of them the wine maker is not getting the cork to seat flush with the opening of the bottle when using your standard kit hand corker. I am seeing about 1/4" to 1/2" of cork sticking out and they make no mention of it. It's annoying me, I have slight OCD and I'm not much of a half asser. I know the best solution is to buy a better corker, perhaps a floor corker, but I'll be using my hand corker - at least for now - and I don't want any corks sticking out like that. I plan to use PVC shrink as a final touch on my product but I was wondering if anyone had any tips to make sure this issue is prevented. Is it as simple as pushing down harder or in a faster motion?
