Evaluate Uganda green coffee before you commit. Request pre-shipment samples from UCDA-licensed exporters, learn the evaluation process, and make informed sourcing decisions for your next container order.
Requesting Uganda coffee samples follows a straightforward four-step process. From selecting your grades to evaluating pre-shipment samples, here's what to expect at every stage.
Choose the coffee grades and growing regions you're interested in evaluating. Review Uganda's available Robusta grades (SC18, SC15, SC12) and Arabica grades (Bugisu AA, A, B, PB). Specify your quality requirements, processing method preference, and any certification needs.
Contact UCDA-licensed exporters with your sample requirements. Provide your name, company, preferred grades, and volume estimates. Most exporters respond within 24-48 hours with available offers and shipment confirmation. Request from multiple exporters to compare quality.
Exporters prepare and ship your samples within 2-3 weeks. Green samples (200-500g) and roasted samples (100-200g) are dispatched via DHL or FedEx. Samples are drawn from the specific lot offered for sale, ensuring what you evaluate is what you'll receive.
Upon receiving samples, roast, cup, and evaluate against your quality specifications. Approve the samples that meet your standards and proceed to negotiate a full container order. Most buyers complete evaluation within 3-5 days of delivery and confirm their purchase decision.
When contacting Uganda coffee exporters, provide the following information to receive the most relevant samples. This is not an online form but a guide to what information buyers should prepare.
Use this checklist when contacting UCDA-licensed exporters. Providing complete information helps exporters match you with the most suitable coffee lots and ensures a faster response.
Understanding sample sizes, shipping methods, and costs helps you plan your evaluation process. Here's what Uganda coffee sample requests typically involve.
Standard green coffee samples range from 200-500g per grade, providing enough beans for multiple roast batches and cupping sessions. Roasted samples are typically 100-200g, sufficient for a cupping table evaluation. For production roasting trials, some exporters will ship up to 1kg of green coffee upon request. Always specify your preferred sample size when contacting the exporter. If you need to run production tests, request a larger green sample upfront.
Samples ship internationally via DHL or FedEx, the two primary couriers used by Uganda coffee exporters. Transit time is typically 5-10 business days after dispatch. Exporters usually prepare and ship samples within 2-3 business days of receiving your request. Plan for a total of 2-3 weeks from initial inquiry to having samples in hand. Expedited shipping options are available at the buyer's expense for urgent evaluations, reducing transit to 3-5 days.
Sample coffee from UCDA-licensed exporters is typically free for serious buyer inquiries. Standard shipping costs via DHL/FedEx are usually covered by the exporter. For large sample requests involving multiple grades, origins, or exporters, the buyer may be asked to cover shipping costs. Specialty microlot or auction-grade samples may carry a nominal fee, which is typically credited against a future purchase. Always confirm cost arrangements before samples are dispatched to avoid unexpected charges.
Professional green coffee evaluation follows a systematic process. Use these six steps to assess Uganda coffee samples against your quality standards and the exporter's stated specifications.
Spread the green sample on a mat under good lighting. Check for color uniformity across beans. Consistent color indicates even drying and processing. Look for foreign matter such as stones, husks, or sticks. Note any discolored beans (black, sour, or faded) and assess overall bean appearance and shape. Uniform, clean beans with consistent color are a strong indicator of well-processed coffee.
Use a calibrated moisture meter to measure the water activity and moisture content of the green coffee. The acceptable moisture range for export-grade Uganda coffee is 10-12%. Coffee below 10% may have lost volatile compounds and appear faded. Coffee above 12% risks mold development during transit and storage. Record moisture readings for each sample and compare against the exporter's stated moisture specification.
Pass the green sample through a set of standardized screen sieves (screens 12 through 20) to determine the bean size distribution. Verify that the sample matches the claimed grade: Bugisu AA should be predominantly screen 18+, SC18 Robusta should be screen 18+, and so on. A tight, consistent screen size distribution indicates careful sorting and grading at the dry mill. Wide variation may indicate inconsistent grading.
Weigh out a 350g green sample and sort through it to identify and count defects. Uganda follows UCDA grading standards with specific defect tolerances per grade. Count full defects (black beans, sour beans, fungus-damaged) and partial defects (broken, chipped, insect-damaged). Tally the total defect equivalency against the grade specification. A grade-compliant sample should fall well within the allowable defect tolerance for its declared grade.
Roast a 100-150g batch to a standard medium roast level (Agtron 55-65, approximately 30-60 seconds past first crack). Observe roast consistency: even color across the batch indicates uniform bean density and quality. Check for roast defects such as tipping, scorching, or facing. Note the roast development time and temperature curve. A clean, even roast with no defects suggests well-processed, properly dried green coffee.
Evaluate the roasted sample using the SCA cupping protocol. Assess fragrance (dry grounds), aroma (after adding hot water), and then break the crust at 4 minutes. Evaluate flavor, aftertaste, acidity, body, balance, uniformity, clean cup, and sweetness. Score each attribute on the SCA scale. For Uganda Arabica, look for winey, chocolate, and stone fruit notes. For Uganda Robusta, evaluate body, earthy character, and clean finish. Record all scores and tasting notes for comparison and purchase decisions.
Pro tip: Cup samples blind alongside reference coffees
For the most objective evaluation, cup Uganda samples blind alongside your current reference coffees. This removes bias and gives you a true comparison of quality. Many professional buyers cup Uganda samples against Colombian, Brazilian, or Vietnamese reference samples depending on the grade and intended use.
