    In grain fermentation rousing yes or no?

    I've tended to do something like this most especially if I have fermenters that are taller than they are wide (H:D ratio higher than 1.2). I've had problems with tall and skinnies with CO2 being forced into solution by the weight of that mash that putting the yeast under additional stress. Particularly with grain-in mash I'm a fan of some agitation during the later stages of ferm. I've tried pump over but I think it's too stressful.

    greasy white stuff in stripping run

    Straining some of that oil out can help control astrigency in the finished spirit. I've found that the spirit can have a slightly rancid finish on a high wheat mash bill if I let all of that stay in, but I was working with a vodka so it may be less of an issue with a gin.

    Running plates

    I've always understood that you're better off using the plates that are closest to your partial condenser, so the higher plates. I think this probably leads to better control over the plates themselves as you adjust your reflux from above.

    the use of grape leafs

    Black currant leaves are pretty good with the right amount of sugar to balance.

    Vodka in pot stills or column?

    There is language in the CFR about NGS and filtration. It's not something I understand but many people seem to be of the impression that some process is necessary to re-designate NGS as vodka. They often accomplish this through carbon filtration. I remember reading something about it but again, I don't really get it.

    Vodka in pot stills or column?

    I've run GC analysis of lots of NGS and it doesn't have any congeners in it if the producer has done their job properly. There may be some sloppy stuff on the market and I've smelled NGS that was shipped in a tote that had kerosine in it and was fouled, but you're getting 96% ethyl alcohol with almost nothing else. That's not to say that distilling it doesn't change the mouthfeel and flavor of NGS, it absolutely does but this is probably because the spirit has never seen copper and so has sulfur compounds in it. Those are removed by copper contact which improves the sensory qualities but this is not a function of cuts.

    Rectify GNS before making Gin?!

    John, Have you seen any data on SA/V ratio of copper to liquid and sulfur binding or concentration of esters produced in distillation etc? I can't find anything and that always makes me mad. Someone has this info.

    Rectify GNS before making Gin?!

    All due respect John but as a fellow GCMS enthusiast I have to say that the differences in the pallet effect of a copper rectified NGS and non are pretty extreme. I was never able to confirm it analytically but my guess is that NGS having been produced on stainless equipment has sulfur compounds in it that are removed by the copper contact during rectification on a copper still. That's not to say that the entire still need be made from copper, I believe sulfur is removed at the point where vapor is condensed against the copper helmet or column.

    Mobile forum tools

    Might I suggest enabling a mobile forum tool for the forums? I use Tapatalk to follow and participate in other forums I'm a part of and the mobile notifications aspect makes it much easier for me to follow threads and participate. I'm not sure how the enabling process works but I've tried to add the ADI forum and I'm pretty certain something has to be done at the admin end to enable it. Thanks

    Infusions

    Did you get any solids settling out? I've done a cherry bourbon infusion that lost its cherry over time. I noticed sediment and guessed that the cherries either lowered the proof or the pH or both, allowed some oak solids to settle out of solution. I think this might have adsorbed some of the cherry flavor and sugars.
