We are excited to tell you about our products as we believe they are unique. We are the trend setters. We are breaking tradition in the beer/wine making industry. We are first to manufacture a small affordable 60 degree conical out of high density polyethylene (HDPE) plastic. Our products are affordable, easy to use, and friendly. The plastic is completely inert. It is also top quality, used by medical companies, hospitals and research companies world wide, where sanitation and sterilization is extremely important.

We have broken all barriers. In the beginning, beer was made by Egyptians in stone crocks. The Belgium’s improved using wood sealed with pitch. Then copper was used in the big beer producing countries. In the 30’s stainless steel was developed, and became the standard in the ‘60s.

Today we use high density polyethylene plastic. Our business began in 1997. It has been a fun fight and we are winning, as the business is growing. We now ship world wide. If you have any inquiries, please visit FAQ or send us a note.

There are three reasons why small batch brewers and wine makers buy the Minibrew fermenters. Less work, less expensive and more fun. There is more, now you can make your favorite beverage with professionally designed small batch equipment. Beer, wine, mead, teas, you name it. You’ll be happy you joined the Small Batch Gang. The flavor is up to you. Our heavy duty polyethylene equipment is completely inert. It will not change the taste. Be sure to buy the size that fits the recipe.
Easy to clean and sterilize. All popular cleaning and sterilizing agents can be used on our plastic fermenters. They will not harm the inert plastic material. Hot water heated to 180 degrees will sink into the plastic and all the parts, killing any bacteria. This procedure works with stainless also. The large top makes it easy to get inside and scrub the dried trub if you should forget to wash it out while it is still moist. Use a Teflon scouring pad or cloth.
Scratches. One need not worry about tiny scratches in plastic or stainless. There are two answers to the problem and both are easy. First do nothing. Leave the scratch, clean it with a soft brush and sterilize with hot water. The second answer is to remove the scratch by cutting down the sides. Use a dull knife drawing it toward you, scraping away the plastic. Grinding and buffing scratches in stainless steel is complicated.
No secondary transfers. There is no need to transfer to a secondary fermentation vessel. It is less work and safer to transfer the lees or dead yeast cells from the bottom while you leave the fermenting process above untouched. Think about it! How many small batch brewers go to great effort to transfer almost finished beer or wine from one carboy to another so the finish product is not sitting on dead yeast cells or lees. It takes less effort and is less risky from an infection point of view, to remove the small volume of junk that has settled to the bottom than it is to siphon the whole batch to another vessel. We recommend removing the trub daily to prevent off flavors and to use the extra liquid to measure specific gravity. You might even sneak a taste. Wine does not produce as much and may only require removal once a week. Eliminating the secondary transfer is only one of the reasons for the conical design. If you are crushing grapes a second container may be required.
Fermenter design shape. The precise shape of the 60o cone and top cylinder (one unit wide by one unit high plus) are fermenter design perfections developed over many, many years by dedicated brewers looking to improve taste, consistency and ease of use. The shape positions the yeast and convection does the rest. The mixing motion of the currents assures complete yeast wort/wine contact. The yeast near the cool sides will sink and upon hitting the conical bottom are forced into the center where it is warmer. Active yeast tend to give off heat. The hard working warmer cells rise to the top and spread to the sides to complete the cycle. Dead yeast cells will drop to the bottom for removal.
Thermometer threads. The MiniBrew System brand of fermenters have thermometer threads located near the middle of the liquid for precise temperature monitoring (not available on the Affordable Conical). A screw-in plug is included with the purchase. Two different HBE thermometers are available and sold separately. See the back page for a complete description of our thermometers.
Lid sealing gasket. A lid sealing gasket is available if you feel the need. While we do not feel it is necessary to seal the tank we have a gasket.
Valves included. The 1/2 inch racking port threads are located on the side of the cone just above the settled yeast level. The port valve is for sampling, specific gravity reading and of course racking to bottles and kegs. The valve at the apex of the cone is for filling the fermenter and draining dead yeast. The thickest of yeast will flow through this large valve one inch valve.

All this without lifting a carboy, siphoning risk or breaking glass. Now small batch brewing is easy and professional. Carboys, plastic buckets, converted kegs and stainless are history. They just do not provide the benefits, ease of use or low cost.

Other uses. A billion dollar medical company buys our conical tanks for use in a blood plasma separation process. They tell me our plastic tanks are superior to stainless steel, sterilize without pitting and are more cost effective. Plastic is also the material of choice at modern research laboratories. These labs handle every kind of bacteria imaginable. Plastic is safe and it works.

What benefit does stainless steel provide at three times the price?
