That's funny since I used a floor corker, purchased last week, to bottle up a BarleyWine in 750ml Belgian bottles using the proper corks and cages. Sure, it took a little figuring out, but it was 100% do-able... Corked the first one, after setting the stop to what I thought was low enough, then adjusted to get closer to the desired depth. After that, it was almost production line, although a little slower going than using the Grolsch bottles I normally do... I will be getting one of the wire cage tools before doing it again though. I used a phillips head screwdriver to wind up the cage wire... After a couple I looked at my right hand and noticed I was bleeding from my index finger... I must have been nipped by one of the cage caps. Never even felt it.
I'm looking to get some more Belgian style bottles from the LHBS next week. That way I can use some for an old ale sitting on some oak chips as well as a few more brews in process. I'll need to get some more Grolsch bottles too, and maybe I'll finally break down and get some 375ml/12oz bottles and caps (will need to get a capper too

) so that I can give some away to friends/family and not care if they don't return the bottles.
I do think that I'll end up with a champagne corker eventually though... I see it as being an easier way to bottle in the Belgian's. Mostly due to the champagne corker being made to take the exposed cork into account. I just wish I could find some dark/black champagne bottles already...
