Coffee Brewing
At Ostova Coffee, we believe that the magic of coffee goes beyond the beans. It’s in the brew, the ritual, the moment of transformation from ground coffee to liquid gold. Whether you’re a seasoned barista or a coffee newbie, understanding the different brewing methods, the equipment involved, and the impact on flavor profiles is key to unlocking the perfect cup. Let’s dive into the fascinating world of coffee brewing and explore the best ways to bring out the unique flavors of our exquisite Indonesian coffee.
Pour Over
Equipment: Dripper (like Hario V60, Kalita Wave), Filter, Kettle, Scale, Timer
Grinding Process: Medium-fine grind, similar to the texture of table salt
The pour-over method is all about precision and control. It involves pouring hot water over coffee grounds in a slow, circular motion. This method highlights the complex flavors and aromas of our single-origin Indonesian beans, producing a clean, balanced cup with pronounced acidity and a smooth finish.
Impact on Flavor: Expect a bright and nuanced cup with distinct flavor notes. The slow extraction emphasizes acidity and clarity, making it perfect for highlighting fruity and floral notes.
Pro Tip: Use a gooseneck kettle for better control over the water flow, and aim for a brewing time of about 3-4 minutes.

French Press
Equipment: French Press, Coarse Coffee Grinder, Kettle
Grinding Process: Coarse grind, resembling sea salt
If you prefer a fuller-bodied, robust coffee, the French Press is your go-to. This immersion method involves steeping coarsely ground coffee in hot water for about 4 minutes before pressing the plunger down to separate the grounds. The result is a rich, heavy cup with deep flavors and a velvety texture.
Impact on Flavor: Produces a full-bodied cup with a rich mouthfeel. The extended contact time between the water and coffee grounds enhances the extraction of oils and flavors, resulting in a bold and complex profile.
Pro Tip: Stir the coffee grounds and water mixture before placing the lid to ensure even extraction.
AeroPress
Equipment: AeroPress, Filter, Kettle, Scale, Timer
Grinding Process: Fine to medium grind, similar to table salt but slightly finer
The AeroPress is versatile and perfect for those who love experimenting. It uses air pressure to push water through coffee grounds, resulting in a concentrated, espresso-like brew in about a minute. Depending on your preference, you can adjust the grind size, water temperature, and brew time to create a coffee that’s uniquely yours.
Impact on Flavor: Yields a smooth, clean cup with a rich flavor. The short brew time reduces bitterness and acidity, making it ideal for highlighting sweeter and more balanced notes.
Pro Tip: Try the inverted method for a more extended steeping time and a bolder flavor profile.
Espresso Machine
Equipment: Espresso Machine, Fine Coffee Grinder, Tamper
Grinding Process: Very fine grind, almost like powdered sugar
Espresso is the heart and soul of many coffee drinks, from cappuccinos to lattes. An espresso machine forces hot water through finely-ground coffee at high pressure, producing a rich, concentrated shot topped with a layer of crema. This method is ideal for highlighting the bold, intricate flavors of our Indonesian beans.
Impact on Flavor: Produces a concentrated, robust flavor with a creamy texture. The high pressure extraction brings out intense flavors and aromas, making it perfect for those who enjoy a strong, full-bodied coffee.
Pro Tip: Consistency is key. Make sure to evenly tamp your coffee grounds for uniform extraction.
Extracting a Perfect Espresso Shot
Cold Brew
Equipment: Cold Brew Maker or Large Jar, Coarse Coffee Grinder, Filter
Grinding Process: Coarse grind, resembling breadcrumbs
Perfect for hot days, cold brew is all about patience. Coarsely ground coffee is steeped in cold water for 12-24 hours, resulting in a smooth, low-acid coffee concentrate. Serve it over ice or dilute with water or milk for a refreshing, mellow drink.
Impact on Flavor: Results in a smooth, mellow cup with low acidity and a natural sweetness. The long steeping time at a low temperature extracts fewer bitter compounds, making it perfect for those who prefer a less acidic coffee.
Pro Tip: Use a 1:4 coffee-to-water ratio for a strong concentrate that you can dilute to taste.

Moka Pot
Equipment: Moka Pot, Medium-Fine Coffee Grinder, Kettle
Grinding Process: Medium-fine grind, similar to table salt but slightly coarser
The Moka Pot, also known as the stovetop espresso maker, brews coffee by passing boiling water pressurized by steam through ground coffee. This method produces a strong, espresso-like coffee that’s perfect for a quick, flavorful cup.
Impact on Flavor: Creates a strong, bold flavor similar to espresso but with a slightly more pronounced bitterness. Ideal for those who enjoy a robust and intense coffee experience.
Pro Tip: Use preheated water to speed up the brewing process and avoid a burnt taste.
Siphon
Equipment: Siphon Brewer, Medium Coffee Grinder, Heat Source
Grinding Process: Medium grind, similar to sand
For the adventurous, the siphon method offers a theatrical brewing experience. It uses vapor pressure and vacuum to brew coffee, resulting in a clean, aromatic cup. This method is perfect for showcasing the delicate notes of our Indonesian beans.
Impact on Flavor: Produces a delicate and aromatic cup with a clean finish. The precise control over brewing variables allows for a highly refined extraction, emphasizing the subtler flavor notes.
Pro Tip: Stir the coffee grounds mid-brew to ensure even extraction and enhance flavor.
