Foam Inhibitor- 1 oz.

This product is food grade silicone based, which is similar to what is used by major name brand soda bottling manufacturers to prevent foaming in the manufacturing and bottling process. When making homemade root beer or sodas made from homemade syrup (strawberry for example) using fresh fruit, they can tend to get very foamy and make it difficult to carbonate. 1-2 drops of this product in the soda bottle keeps this foaming to a minimum, allowing me to use the soda maker to force carbonate the soda. If you make homemade root beer or sodas, this can be added to prevent excessive foaming with forced carbonation methods or traditional yeast in the bottle methods. The bottle is small but you will only use 1 or 2 drops at at time so overall, I believe it to be cost effective.

first time using this stuff and Ive brewed beer for 8 years. lowering hydrophilic interaction, what a great addition to any homebrewers closet. This order came with 2 bottles, assuming 0.5 oz each. I didnt look at the label. I added about 12-15 drops to during my boil and and broke up the foam within a few minutes. No risk of boil over. In my brewing experience I've have 4-5 boil overs, they can sneak up on even veteran brewers. When your making a 10 gallon or higher batch removing the heat source is not an option, stirring can cause the boil over to accelerate before break up. This product is a sure fire way of eliminating the issue. Now as of what it does to the beers flavor, I do not know yet. I will find out in 6 weeks.

This Fermcap saves me a lot of hassle during my brew day. I can just add a few drops and no more boil over scares. This product is inexpensive and the convenience outweighs the price.

The stuff works great for keeping your kettle from boiling over. Looks can be deceiving though, you don't receive two 0.5oz bottles, but one 1oz bottle. No biggie but be aware.

Unlike all the home brewers who buy this product, I use it to cut down on foam when I make smoothies. Casein and whey protein can be terribly foam when you blend them for anything more than a whirl or two, and this knocks out the foam almost completely. I love it for that. It’s also great for when you’re cooking things that love to bubble out of the pot. How much do I use? Let’s do some measurement math. The bottle notes that the defoamer should not be used in excess of 200 PPM (this is the max concentration approved by the FDA). That is about 11 drops per gallon, max, or about 2.5 drops for one quart of liquid (more or less my smoothie size). If that’s the max, what’s the minimum effective amount? The bottle states that the low end of the scale is 1 drop per gallon, or approximately 0.25 drops per quart. How do you get 1/4th of a drop out of the dropper bottle? You can drop it into a small measured quantity of water (say, 4 Tbsp.), mix it, and use 1/4th of the quantity, saving the rest for another time (or spill it out). For my daily smoothie routine, this became a hassle, so what I do is squeeze out a bit until it just starts to bulge from the dropper, and dab that onto a spoon which I stir into my smoothie liquid. Is it exactly a quarter drop? Probably not. But it’s definitely far less than the 2.5 drop maximum concentration. And that amount seems to be ideal for cutting foam for my purposes. Some folks might ask, is this safe to consume? The answer is yes. The defoamer is made from silicone, but don’t freak out, it is the same compound that food manufacturers use to cut foam in their liquid food products. And as noted, it’s FDA approved for use up to 200 PPM. How do I know? My food scientist ex confirms this. If you’re a person who is super granola, all natural and aggressively organic, you’ll probably shrink in horror at the thought of consuming a chemical, whether or not it’s been tested and approved by the FDA. That’s fine — I assume you are also probably OK with smoothies that have 2 inches of foamy head on them. You do you. As for me, I’m ok with the relative risk of consuming half a drop a day in exchange for glorious foam-free smoothies. I’ll update this review if it turns out I get silicone-induced cancer in 20 years - stay tuned!

Great product for making beer and other food that is boiled and can foam. For beer making, it helps prevent foam overs in the boil and in fermentation processes which can make a HUGE MESS. They have no adverse effects on the final product. Use as directed on the bottle.

This flat-out changes your brew day. I hate it when my boils foam up and prevent me from seeing how much volume I have left not to mention the residue it leaves all over the kettle. I also hate it when I'm making a yeast starter and the thing foams over. GRRRRR!!!!! I am typically doing several things at once and having to babysit a boil is extremely inefficient. Enter the Fermcap-S Foam Inhibitor. I love this stuff. It doesn't change the flavor of your beer AT ALL and it prevents the boil from foaming all over Tarnation! It's very affordable and an excellent addition to your brew day routine!

Not sure I'd add this to a beer... But adding the Fermcap-S to whiskey wash before distillation just makes the difference! With ration 1ml/gallon it suppresses the foam good enough, allows to the wash boiling and releasing the alcohol without the mess around. Recommended.
