  1. I just pissed myself.
  2. As @JustAndy said.. Bobby_M at has tons of fittings. I've also used for larger TC fittings that don't apply to your problem.
  3. Can you provide more details on your whiskey still. We experienced that in reverse -- made gin in our column still and had a tinge of flavor carryover into a neutral spirit. After our standard CIP protocol we backflushed with PBW followed Acid #5 (both from Five Star) through the parrot triclamp connection through the lyne arm, etc. That did the trick. So the answer is yes, you can do it, but it's a bit of a balls ache.
  4. Yes, Im aware of that. But your post above could be read that antibiotics are added to the distillate not used to clean up fermenters.
  5. That's a joke, right??
  6. Truer words were never spoken
  7. Let it patina like an old penny. Save yourself the frustration. You'll have a thousand other things more important than keeping your copper shiny.
  8. Masters in chemistry, while helpful, is far from necessary. What you really need is a process engineering consultant for about a year, a stellar marketing company, compliance officer, and CFO. Oh, and a shit-ton of money. Distilling is by far the easiest thing about running a distillery (and probably, after the first year, the most boring).
  9. You may be in for a challenge with that grain bill. Assuming they have a standard wedgewire false bottom that much corn and rye will clog up tighter than a cat's butthole. Single malt? Absolutely. Milled into a cornmeal consistency -- hardly ever. Now, you could have them mash and then use a FIP to slurp the slurry and take it your place for fermentation. As for your question, whats the total size of the mash tun?
  10. I'd be interested in hearing more about your setup. 10 psi steam has a volume of somewhere around 16 cubic feet / lb. Your boiler produce around 500 lbs of steam (I think) / hour which is enough to completely fill a small home. I can't for the life of me figure out how a jacket on a 265 gallon kettle has enough volume to hold that amount of steam. Does you WM have the ability to underfire the burners or are they open to atmosphere / bunsen style?
  11. It'd guess minerals in the water. Do you have a TDS meter? Are you using an ion exchange column after your RO system?
  12. Do you have a steam accumulator?
  13. Assuming 75% efficiency you're looking at either 300 kbtu or 450 kbtu. His heating needs are: 200 gallons = 1668 lbs 200 gallons from 75F to 212F = (212-75)*1668 = 228,516 BTUs 200 gallons from 212 to vapor = 970 * 1668 = 1,617,960 BTUs In my experience he won't have enough load for the boiler to run efficiently -- it's going to be short cycling to beat the band, and although it's not hard on the boiler, it will kill efficiency ($$$$). He needs roughly 250kbtus to heat up the still to boiling and another 1.6mbtus to vaporize the entire contents of the still (clearly he won't be doing this). The question that's difficult to answer is how fast can the heat be transferred from the steam jacket to the contents of the kettle. Delta-T is a factor (operating the boiler at 9 psi rather than 2 psi has it's advantages) but so is the architecture of the kettles (a "tablet" shaped is better than a cylindrical shape). I'd bet he wont see appreciably faster heatup times with a 600k than a 275k boiler because of the heat transfer rate and the fact the boiler will have serious short-cycling problems -- a 600k boiler wont push heat in any quicker than a 400k boiler. That being said, when he upgrades to a larger still he'll be good to go.
  14. Incorrect. You can use a 3Å molecular sieve.
