As well, I'm going to wrap my Reflectix with a Graincoat as soon as it arrives. The timer was a great idea, although I went with a rugged, waterproof Taylor with a magnetic bracket. I recently purchased a Grainfather here in Canada (yes we run on 110-120V too) and was able to "pimp up" my unit and do lots of reconnaissance.

For now, I just use 75% as a baseline.įotofisher, I want to thank you for all your tips, videos and info sharing. Just my observations, more batches with the Grainfather will prove out my system efficiency. So yes, there's lots of sugars there to eat - another clue that 91% may be more accurate than not. That batch is still bubbling away in primary, 10 days into it now. I didn't rush sparge on that batch, and even used a little extra sparge water that wasn't called for. With the 91% brew, I re-calculated and re-calculated and sure enough, it is 91%, I couldn't believe it. The 69% brew, I rushed the sparge process. * with three batches through the Grainfather, I have experienced efficiencies from 69% to 91%. And, sparging thoroughly will ensure you are washing all the sugars from the grains. Beta rests convert faster than alpha rests. Hitting mash temps is critical for extracting the type of sugar you desire, waiting there long enough allows the mash water and temp combination to do the trick. * I believe mash efficiency is driven by three things you can control: hitting accurate mash step temps, giving the mash step enough time, and sparging THOROUGHLY with sparge water.

Here are a few of my thoughts.mind you, I am NOT a professional at this, I am just an avid hobby brewer that tends to get in the weeds with everything. Sooooooo, here's my thoughts on "boil".Ĭlick to expand.I do calculate efficiency, and I use Beersmith too. As long as the boil temp is reached and held for 60 mins or so, that does the trick for me.

So, full circle here - I don't need a roily boil to make me feel good about the wort. Sure enough, the wort boils and doesn't get too hot to scorch the bottom. I live at 4,200 feet, so boil temp is 203F. How it knows when the wort is boiling or not is beyond me. I don't know this for a fact, but the Grainfather appears to have a built-in temp governor that when boil is reached, it maintains just enough heat to keep it going, not pushing it over the edge to a roil. I actually like a more modest boil for a few reasons:Ģ) wort doesn't burn and muck up the bottom of the boil pot, which can give a burnt flavor to the beerģ) coming to a modest boil versus roil boil helps reduce boil overs during the first 20-mins or so. With that said, the boil in The Grainfather is more modest than with a 50,000 BTU propane flame sitting on the arss-end of the boil pot.

The Reflectix wrap certainly helps with maintaining temperatures and reaching boil a tad faster. Once the wort reaches boiling temp and the liquid is moving around, does it matter how fast it swirls and moves? The more aggressive the boil = the more evaporation loss.
