Folks, recently fully licensed and producing and having issues to work through (and I know we will continue to have them for quite a while being that we had to start up the "iron man" way without a whole lot of funding or welding experience). In the immediate, our biggest issue (imho) is getting our abv up for our grain mashes so our runs on the still are a bit better. Our main products are all-grain (corn whiskey) and are hovering around a low 5% abv prior to distilling. I'd like to try to get that up, even if just a little, but not sure if it's possible until we upgrade our equipment. Right now we're using a 50 gal. steel pot for mashing using a propane burner, so we can't keep the burner going when we put the grain in. We get the water/sour mash up to boiling, cut heat, add cracked corn, stir every 15 mins, allow it to cook down for a good, solid 90 mins. The lowest the temp will drop is usually 185 F. We then drop the temp (using ice) down to 155 for adding malt and then allow that to work its magic for a good 2 hours (stirring every 30 mins). I've tried adding additional enzymes, doesn't seem to make a lick of difference. When we move the mash to the fermenter, we have to separate/strain the grain by hand because we can't put the solids in the still and I'm not comfortable with risking moving the solids with our diaphragm pump based on the manufacturer's recommendations (plus it isn't fun to get that grain out of the fermenter after we would pump out the liquids). I know that we're doing it pretty rudimentary, but that's what we've got to work with until we can build up a bit. And to answer some questions up front, no we can't soak the corn prior to (it's cracked and we use the heck out of the cooker being that it takes 3 cooks to fill a fermenter, that's also why we have to move the mash once it's done enough so we can begin another cook). Our products are turning out great, we just can't produce a whole lot going on like this and we'd like to start stocking as many shelves as possible. All of that being said, maybe someone can recommend a cheap 150-250 gal. cooker that will alleviate most or all of this. It is in the cards to upgrade most/all of our equipment as soon as we can, so I realize that. Any feedback, suggestions are greatly appreciated, thanks guys.
