As the Indian home espresso market grows at 6.1% annually (TechSci Research, 2024), many users face a critical challenge: achieving consistent, café-quality results. Despite investing in quality equipment, 60% of home baristas struggle with under-extracted or bitter espresso due to improper calibration.
This official guide outlines the essential "dialing in" process – the systematic adjustment of grind size, dose, and extraction time – to unlock your machine’s full potential. Whether you’re using a budget-friendly model or a premium system, mastering these techniques will elevate your home brewing to professional standards.
What is “Dialing In” for Espresso?
Dialing In is the process of adjusting grind size, coffee dose, and extraction time tooptimize flavor when brewing espresso. This calibration ensures balanced acidity,sweetness, and bitterness, and is considered the most critical skill for home espressomaking. Professional baristas estimate that dialing in accounts for 70% of espresso quality, while machine quality contributes only 30%.
How to Dial In Espresso in 4 Steps
1. Weigh the coffee dose
Start with 18g of fresh coffee beans for a double shot – the standard for Indian home brewing. Use a digital scale for precision, as even 1g variations affect flavor.Indian Tip: Choose locally roasted beans like Blue Tokai or Third Wave for best results.
2. Adjust grind size
For India's popular Monsooned Malabar beans, aim for medium-fine grind (table salt consistency). For Kochi Arabica, use medium-coarse (granulated sugar texture).Test: If water flows too fast (under 20s), grind finer; if too slow (over 35s), grind coarser.
3. Control extraction time
Extract for 25-30 seconds to yield 30ml of espresso. This "golden ratio" (1:2 coffee-to- water) balances flavor compounds.Visual cue: Look for a steady, honey-like flow with golden crema on top.
4. Taste and refine
• Sour espresso: Under-extracted → grind finer or increase extraction time
• Bitter espresso: Over-extracted → grind coarser or decrease extraction timeRecord your settings and repeat until you achieve a balanced, sweet-tart flavor profile.
India-Specific Dialing In Tips
Hard Water Solutions (Delhi/Mumbai)
Use the CostarCosmos 20 Bar Basic with built-in anti-scaling filter, or add 1/4 tsp baking soda per liter of water to neutralize minerals.
Monsoon Humidity Management
Store beans in airtight containers with silica gel packets to prevent clumping, which disrupts grind consistency.
Budget Machine Recommendation
According to the India Coffee Machine Market Growth Report 2024 (TechSci Research), residential demand for entry-level machines is driving 6.1% annual growth. The CostarCosmos Master 2 Plus’s dual brewing system fits this trend, letting beginners practice dialing in with both capsules and ground coffee.
