  1. What is your opinion on using this computerized equipment (other than price)? I just came back from an intensive distilling course where we learned the basics by using hydrometers. They are obviously the tried and true method. Has anyone had any issues with the machines? We are determining if we need to budget one or just stick to the basic hydrometer. Thoughts? Horror stories? Thanks Travis
  2. Hello fellow distillers, We have been told that our vodka should be at 40% abv before filtering with activated carbon. If we want to use our vodka to produce a gin, can we filter it at a higher abv? We were considering doing a gin run with 65% abv alcool to be more efficient. Can we filter a vodka at 65% abv? Thanks all
  3. I use pot still to make distillation . Head finished 83%, hearts 79% end. How could you get lower degree than I collected by using flute still. I dont get it, could you answer me... My Calculation cuts: %14 head, %65 hearts ex:7:25 chapter: Thanks...
  4. I was surprised that I could not find a similar (accurate) equation online, so thought maybe others might find this useful. I recently wrote it as part of a mashing spreadsheet for a client. It allows you to calculate target Original Gravity (OG) by plugging in your target A%V and expected Final Gravity (FG). The only equations/calculator I could find used FG and OG to calculate ABV. This equation can be pasted into a spreadsheet; just substitute FG and A%V for the appropriate cells (assuming I typed it correctly here). OG=(1521600*(FG^2)+(28187*A%V*100))/((1521600*FG)+(15880*A%V*100)) I used the following 2 equations from: Brew by the Numbers by M Hall from Zymurgy Summer 1995 A%W = ((76.08)(OG-FG))/(1.775-OG) A%V = (A%W)(FG/0.794)
  5. Stupid n00b question from a relative first-timer (We just got our COLA! Time to bottle some spirits!) I make a liqueur with a target of 40% ABV. So far I've made 4 batches, all of which are a little bit less than that. First batch, for example tests at 36.75% ABV after re-distilling a sample. I went a little bit under on purpose with the plan of testing the proof and adding a bit more GNS to get the liqueur to the right bottling strength. And now that I'm attempting to calculate how much GNS-190 to add, I'm realizing this may have been much easier the other way around. The dilution calculators and examples that I see out there are geared towards diluting barrel-proof or high-proof spirits with water, not adding GNS to bump up an under-proof batch. I would see what AlcoDens can do for me, but I've got a mac. I was once good at chemistry (like in high school) but evidently I profoundly overestimated how much of that I've retained. Can anyone help me get me in the right direction?
