Since the purchase, I have brewed six 5 gallon all grain batches from my kitchen. Mashing grains has never been easier or cleaner. The only reason I haven’t brewed more is that I’ve filled all my kegs.The process still takes about 4 hours from mash to final cleaning. Still, the Bluetooth functionality from your phone allows you to walk away and get other things done around the house.A couple of things to know:1. I have brewed from 7% beers to 5% beers, IBU’s from 25-70. For higher ABV beers, the mashing takes longer and for big hoppy beers, trub permeates the system. This unit can handle big beers, just make sure you run a good cleaner and sanitizer after each use.2. I use the hop spider rather than mesh bags or directly pitching the hops. I have not noticed any loss of hop flavor or bitterness. Quite a bit of trub makes it out of the spider, but it reduces the clutter around the pump filter and the machine runs more smoothly. I’ve also used the hop spider for other ingredients added for flavor.3. The grainfather website and app are amazing. They keep all your recipes on file and step you through the whole process from mash to drink. It’s a free database that records the OG and FG and finally ABV. It also helps calculate the style of beer you want, quantity of grains and hops for ABV, IBU, color and clarity.4. I brew at 4,500 ft altitude. Boil temp at this altitude is 206, not 212. I can adjust the grainfather to hit the boiling target I want. I would recommend placing the lid on the grainfather and covering the hole on top to increase the boil roll. This requires high temp gloves or pot holders to remove and replace the lid.5. The wort chiller is phenomenal! I can plug the blue cool line to my sink, run the red expel line back into the sink, turn on the pump and cool the wort from 206 degrees tp 65 degrees in 35 minutes. So amazing!This unit with the control box is totally worth the investment in time, quality of beer brewed, and experimentation. Brew on my friends! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars A Must for the Grainfather if you live in the U.S. *by J***K on Reviewed in the United States on July 4, 2020* I live in the US so we of course are limited to 110/120V. The Grainfather will do the trick without the graincoat but I never realized what a difference it would make until I purchased this. My boils are certainly more vigorous and the time to reach boil was cut down by about 25%. I typically brew indoors but I would certainly recommend this if you plan to brew outdoors in cold weather. Another added bonus is it protects you from the accidental burn from brushing up against the Grainfather in the middle of a boil! All I want now is for Grainfather to release the rolled edge bottom and top perforated plates for the 8 gallon model so that I can stop dealing with getting the pesky silicone gaskets! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars awesome *by A***Z on Reviewed in the United States on December 21, 2022* outstanding --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/39062555-graincoat-for-grainfather-g30](https://www.desertcart.tw/products/39062555-graincoat-for-grainfather-g30) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-23*
