Superseding Convertase AG300L, this 500ml bottle treats up to 100 five-gallon batches, improving mash runoff and enabling the production of low-carb, light, and specialty beers with enhanced alcohol content and cleaner finishes. ## Description This is a 500ml bottle of Diazyme X4, a liquid Beta glucoamylase capable of completely breaking down starch and dextrins in the mash or fermenter into glucose for the production of low carbohydrate, light beers, specialty beers, whiskey, vodka and moonshine. It works at 140f and below. You can use it in the fermenter! More aggressive than Bioferm L. or our Alpha Amylase Enzyme powder. Convertase DOES break down the Alpha 1-6 and 1-4 bonds. Advantage over Amylase Enzyme is that this works at fermentation temperatures and converts 100% of starches to fermentable sugar. Increases runoff from grain and corn mash. AG-300 is something special that can convert 100% of the maltose sugars to glucose which would make all of the sugars fermentable by the yeast. AG-300 should be pitched with the yeast and operates in the most cost effective manner at fermentation temperatures. You can check it with iodine test if you get any blue it will be very light. It gets the whole job done! Direct replacement for Convertase AG300 which is discontinued. Review: Giving it a try in making low carb beer- positive results so far - I got back into home brewing beer after a 10+ year hiatus because I've been on a low carb diet for over a year and got bored with the few mass produced low carb beers available (most are terrible and while I've always liked Miller Lite and Guiness Draught on occasion, they've never been my favorites and I missed variety). I haven’t been able to find a lot of good reliable information about low carb brewing, so what I’m relating here is what I’ve learned from the bit of information I’ve found and through trial and error. I’ve tried 3 approaches to brewing low carb beers: 1) Using less fermentables in the brewing process. Less sugar in equals less carbs in the finished brew. 2) Using a yeast with a high attenuation that will convert more of the sugars into alcohol. 3) Using enzymes to make break down more complex sugars into simple sugars for the yeast to convert into alcohol. I gave up on approach number 1 very quickly due to not being very happy with the finished beers (yes, they were lower in carbs, but also lower in alcohol, so I found myself drinking more of them and liking them less). Caveat before I go on to discuss approaches 2 & 3: a finished low carb beer is not going to have the same body as a beer with more carbohydrates, so attempting to make a low carb imperial stout or “big” brew is not likely to yield good results and not what I’ve been shooting for. My attempts have been to brew a variety of ales that finish between 4 and 5% alcohol and have hop profiles similar to beers I like that have higher (or normal) carbs. Most of my experiments with approach 2 have been using Saison yeast and while I’ve liked the results, Saison yeast can be finicky (frequent problems with stuck fermentation) and it adds a distinct twang that I like, but isn’t right for every type of ale. So that has let me to spend a lot of my time on approach 3. The 3 enzymes I’ve tried are Beano, Amylase, and the product that this review is for- Glucoamylase (or AG300). You can find a lot of information about using Amylase and Glucoaylase when distilling liquor, but not a lot when it comes to brewing beer. Beano- My advice is don’t use it. It definitely makes for a low carb beer, but it’s overly aggressive at breaking down sugars and it just doesn’t stop until you’re left with nothing but alcohol water. Amylase enzyme- good finished beer, but not that much lower in carbs than without it. 3 times I’ve made 2 batches using the same ingredients but with Amylase in one and not the other. The batches with the enzyme have resulted in slightly lower gravities than in the batches without it, but not enough of a difference to get excited about them. This product- glucoamylase, AG300. Have tried it in 2 batches- a pumpkin ale and an Irish stout. Poured the liquid enzyme into a dropper bottle and then used just a drop in each 6 gallon carboy used as a primary fermenter. It’s aggressive, but not nearly as aggressive as Beano. Irish stout finished much dryer than I’ve been able to get it to finish without the enzyme (but not like the alcohol water of the Beano brau). Same thing with the pumpkin ale. The Irish stout is only just carbonated and the pumpkin ale is still being keg conditioned. Making both an ale and a lager using this enzyme this weekend. Will update this review as my batches using it age, but initial results are promising. UPDATE: Promised an update and then forgot it. Have now been using this glucomylase enzyme in almost all my homebrew for a couple of years with great results as far as getting a lower than typical final gravity (which means more alcohol, less finished carbs). There have been 2 batches where I used a bit too much and ended up with a higher alcohol beer then I was shooting for but those batches were still OK-just a bit thin- but still beer unlike the batches I made with Beano that started OK but ended up as carbonated alcohol water. I've been very happy with most of the other batches.

I have gotten close for far less in cost.. also, Shipping was 5 days over the promised date. ## Frequently Bought Together - GLUCOAMYLASE AMYLASE ENZYME DIAZYME X4 AGGRESSIVE LIQUID CONVERTS ALL STARCH TO SUGAR IN WORT AND MASH REPLACES CONVERTASE AG300L - BSG Handcraft Amylase Enzyme - 1 lb. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/58975335-glucoamylase-amylase-enzyme-diazyme-x4-aggressive-liquid-converts-all-starch](https://www.desertcart.vu/products/58975335-glucoamylase-amylase-enzyme-diazyme-x4-aggressive-liquid-converts-all-starch) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
