Wine bottles with 17mm opening?

[ccaissie]

I'm getting ready to bottle 6 gals of Sauvignon Blanc, my first time with a real wine brew, and I have several types of bottles. I expect to down them in a year or so.

I'm ok with buying screw caps for most of the bottles on hand.
Likewise, ok with corking the dozen commercial bottles I have. These bottle's opening measures about 18.3 mm that's about the so called standard 3/4" for #8,9 corks. Got it.

I have a case of heavy wine bottles, new old stock that have a narrower opening, 17.0 mm to be exact. What do I use for those?

Info much appreciated!

Are they sparkling bottles maybe? I know champagne bottles use a 17mm cork

Not especially heavy, but you are probably right. They have a flange which would work to hold the wire bail. If I cork them what size? #7 or #8?

Thanks,

Not even.
17.5mm is a #5 cork

Okay. so the recommended size for a 17mm bore would be the #5? is that the correct compressed fit? Speaking as a machinist, the amount of "interference" is the key to a proper assembly.

I went off this but maybe I read it wrong. As a machinist you would know better

It looks like I went off the outer diameter. My bad
