Well, as indecisive as I am I went with three different corks. I ordered from MoreWineMaking. Here is what I ordered: 1 3/4 in Agglomerated 1+1 (25) 1 3/4" Grade 3 (25) 1 3/4 in Acquamark (25) The Grade 3 corks were rather pricey but I'll be bottling three gallons of the seven year old mead with them. The least expensive was the Acquamark...hopefully they will be a good batch. The Acquamark appear to be a good cork for long-term use...naturally the #3's are supposed to be the best. And, of course, I ordered the bi-discs. This will give me corks to work with over the next year or so, hopefully I'll figure out what works the best for me. Thanks for all the feedback!!!!
