Hey Kal. I appreciate the add. Your site and recipes are very informative. I had a question on this recipe and others. Iím losing about 1.5g in the CFC, pumps, hoses, etc. Should I adjust my hops 8% or so where Iíll have 10.5g or so in the tank?

No. Don't adjust just the amount of hops due to system losses (called your 'brewhouse' efficiency). Losses are normal. Losses happen due to evaporation / expansion / foaming during boiling, grain / hop absorption, chilling / fermentation sediment, racking / kettle / hose deadspace, etc.

Simply make more wort by increasing everything in the ingredients list if you do not end up with enough beer at packaging time. No different than scaling any recipe from one batch size to another. You don't just increase one ingredient amount (like hops) as that would cause an imbalance.

As mentioned above, brewhouse losses are completely normal on any brewing setup be it single vessel 2 gallon BIAB setup used at home, to a 3000 gallon 4+ vessel commercial setup used by major breweries. That why each recipe on my website is designed to produce 12 US gallons of wort, which results in at least 10 US gallons of packaged beer after fermentation and various losses. Feel free to scale that up or down to match your needs and equipment.

Again, these losses have nothing to do with any of my specific recipes or the brewing setup I detail on this website. Losses happen with all brewing setups and with all recipes. Some recipes will lose more or less, usually higher if there are more hops given that hops soak up wort/beer readily. (Example: I tend to make 12 gallons post boil when making beers with lots of hops and only 11 gallons post boil when making beers with very little hops, but to keep things simple I post all my recipes as 12 gallon post boil to avoid confusion).

Cheers!

Kal

Question split out of this thread and moved to the "Brewing Techniques" forum (as questions on brewhouse efficiency are not related to the Electric Hop Candy Jr. recipe).

New thread is here: http://www.theelectricbrewery.com/forum/viewtopic.php?t=32032

Cheers!

Kal
