The "Coach" doesn't just use one number. It analyzes your Development Time Ratio (DTR) and Weight Loss % against your own custom targets. It then cross-references this with the roast's Rate of Rise (RoR) to identify stalls or runaways, giving you a strategy that's based on the entire roast, not just one number.
When you enter a Start Weight (e.g., 410g) and an End Weight (e.g., 340g), the tool instantly calculates your moisture loss (17.1%). It then pulls the green bean price from your library (e.g., $4.50/lb) to give you your true cost for that roasted batch, both in total and per pound.
This tool uses your browser's private localStorage. When you log a 410g roast (0.90 lbs), it automatically subtracts that amount from your saved inventory, so you always know what you have in stock.
The parser is built for roasters. You can just enter temperatures line-by-line for 30-second intervals, or you can get precise by adding a timestamp (e.g., "8:54, 188") for key events, and the log will automatically adjust.
My name is Kyle, and I'm the founder of Avy Coffee.
Like you, I started roasting because I was obsessed with quality and consistency. But as my hobby grew into a business, I hit a wall. I was wasting hundreds of dollars on failed 'test' batches of expensive new beans. I was trying to track my costs and inventory in messy spreadsheets, and I was spending more time doing data entry than actually roasting.
I needed a tool that did three things:
Tell me why a roast failed and how to fix it.
Tell me my exact cost-per-pound.
Be 100% private, with no monthly subscription fees.
I couldn't find one. So I built this dashboard for myself.
Every feature in this tool is one I personally needed to make Avy Coffee more profitable and more consistent. It's been battle-tested on my own roasters, and it's the tool that helped me perfect the profiles for the coffee you see in my store.
This isn't just software. It's a roaster's solution, built by a roaster.
The "Roast Coach"(Problem vs. Solution)
Stop Wasting Beans. Start Coaching.
Stop guessing why a roast failed. The "Coach" doesn't just give you a score; it gives you an actionable "Next Roast Strategy."
Our analyzer spots the flaw (like a "runaway" roast with an 18% DTR) and gives you the exact plan to fix it (e.g., "Apply your 'Power Brake' earlier"). This is the tool that turns your expensive, failed batches into your next 99/100 "gold standard" profile.
The "Accountant" (Profit & Costing)
Know Your Numbers. Price for Profit.
You can't be profitable if you're guessing at your Cost of Goods Sold. The "Bean Library" is your business-in-a-box.
When you log a roast, the analyzer instantly pulls your saved green bean price, calculates your weight loss, and shows you the two numbers that matter most:
Cost-per-Batch
Cost-per-Roasted-Pound
Stop guessing at your retail prices. Start guaranteeing your profit margins on every single bag you sell.
The "Pro" Customization
Your Roaster. Your Rules.
This dashboard isn't a rigid, one-size-fits-all system. Your roaster is different from ours, and your "perfect" roast might be different, too.
While the tool comes pre-calibrated with the proven, 97+/100-score "finesse" profiles from Avy Coffee, you have full control. Click the Gear Icon (⚙️) to open the settings and enter your own ideal DTR and Weight Loss ranges. The entire "Coach" and scoring system will adapt to your machine and your unique roasting style.
