The Cassiopeiae stir plate contains a quiet and strong motor and two powerful neodymium magnets of grade N52, the highest grade of neodymium magnet available, superior to the magnets found in most other stir plates.
Cassiopeiae is an affordable powerhouse, while many budget stir plates are unable to stir glycerine and glycerine/propylene glycol mixtures, this is not the case for Cassiopeiae: it can easily stir your favourite glycerine/propylene glycol blend and make sure that your choice of flavor gets distributed throughout the liquid. In the product pictures you will find one showing it stirring a 1000 ml batch.
The Alchemist’s Pantry stir plate model Cassiopeiae measures 18 x 11.5 x 4 cm, and its shell is made out of anodized aluminum and plastic. When stirring brewers wort or water it can be used to stir up to 5 liters at a time, and stand securely on the table thanks to its four rubber feet. It is powered by a compact power supply, please make sure you pick the model you need for your country (available in EU, UK, AU and US versions).
While people have used Cassiopeiae successfully with a wide variety of flasks and other containers, some up to 25L in size, we recommend that you use a quality laboratory flask of up to 5L in size. Use a laboratory stand to support your flask if necessary.
When buying a stir plate from the Alchemist’s Pantry you also get two high quality 2.5 cm (1″) Teflon coated stir bars. The second stir bar can be used to avoid that the stir bar in the yeast starter ends up in your fermenter. Note that flasks and bottles shown in the product pictures are not included.
Stir plates in the brewery
When brewing it is very important to pitch enough yeast and to ensure that the yeast is healthy and ready to do the job you want it to do. The easiest way to achieve this goal is to make a yeast starter using a stir plate.
Making your yeast starter using a stir plate helps you to:
– quickly reach a high number of active yeast cells
– reduce the likelihood of infections
– improve the taste of your brew by promoting a healthy fermentation and consequently diminish the amount of offensive flavors stemming from the presence of excess sulfur compounds, fusel alcohols and diacetyl produced by stressed yeast.
This can be achieved by using an laboratory grade stir plate, but unfortunately these units are very expensive, and quite often bulky and noisy.
Do note that although some of our product pictures shows a vortex reaching from the top of the liquid to the magnet, this is merely for illustrative purposes. We recommend that you set the speed of the stir plate so that at most you see a very small dimple on the surface of your starter. This is to avoid that the yeast is exposed to excess physical stress, which may induce cell stress and production of off-flavors. We have experienced and firmly believe that a yeast starter with a relatively small, but healthy population of yeast will yield a much tastier beer than a yeast starter containing a large population of stressed yeasts.
Stir plates in the kitchen
Just like in the laboratory, stir plates can be very helpful in the kitchen when powders need to be dissolved or something needs to be kept in suspension. Just keep in mind that stir plates are designed to stir free flowing liquids, you should not drown the stir bar in powder or ice cubes: powders should be added gradually and not be allowed to settle around the magnet, and thick drinks with lots of ice cubes are best handled with a blender and a cocktail shaker.
Stir plates and wine connoisseurs
If you have followed Nathan Myhrvold and Modernist Cuisine you may have noted how they aerate wine with a blender – to many wine connoisseurs this is a bit grisly, and some blenders are notoriously difficult to clean completely to avoid residues on the blades contaminating the flavor profile of the wine. With a stir plate the only thing that needs to be in contact with the wine is the Teflon coated stir bar, which is easy to keep clean. A good stir plate also gives you great control over how much you want to aerate the wine, and you have an excuse to take many taste samples as you figure out the perfect level of aeration for a wine!

A note on FDM manufacturing
We utilize fused deposition modeling (FDM) manufacturing to create components for some of our products as it allows us to utilize a wide array of materials for low volume parts and to create structures and textures that can not be achieved using classical injection molding. The result is unique parts which subsequently are put together by hand to ensure high quality products.
Payment & shipping
Import duties, taxes and other charges are not included in the item price or shipping charges; they are the responsibility of the buyer. Check with your country’s customs office to determine what these costs will be before you bid/buy. These charges are usually collected by the delivering freight company and should not be confused for additional shipping charges. We only ship to verified PayPal or eBay addresses.
We ship using the Danish postal service, and package the products safely in non-descript packaging.
The Danish postal service estimates the following delivery times to the countries we sell to:
Northern Europe: 2-4 days
Rest of Europe: 3-6 days
North America: 2-7 days
South America: 5-6 days
Australia: 5-6 days
Asia: 5-8 days
These estimates only cover the time from the package is picked up at our facilities and until it reaches its country of destination. They do not cover the time it takes for your local postal service to transport it the rest of the way to you. For countries outside of Europe customs may delay the transport further, this is out of our control.
You may change your mind regarding a purchase within 14 days of receiving it. Electronics and other equipment must be in the same condition as when you received it. Additionally, when it comes to foods, food ingredients, enzymes for food, and food additives, you must not have broken the seal. The reason for this is simple: We can not guarantee the quality of food if the seal has been broken. Consequently, if you want to test one of these products then we recommend that you purchase the smallest amount possible. Please note that we do not refund shipping costs.
