Cucumbers are a popular vegetable that are enjoyed around the world. Knowing how to pick good quality cucumbers at the grocery store or farmer’s market is important for getting the best flavor and texture. There are a few simple things you can look for when selecting cucumbers.
Appearance
Start by looking at the appearance of the cucumber. A fresh, high quality cucumber should have smooth, firm, and unwrinkled skin. Avoid cucumbers that are very bumpy or have soft spots. The skin color can range from dark to light green depending on the variety, but you want an even color all over. Size is not necessarily an indicator of quality, but very large cucumbers may have more seeds, while very small ones may not be as flavorful. Aim for cucumbers that feel heavy for their size.
Ends
Next, inspect the ends of the cucumber. The blossom end (opposite from the stem) should be rounded or slightly flat. An indented or shriveled blossom end means the cucumber is overripe. The stem end should be smooth and green. Avoid cucumbers with a dried out or brown stem end.
Firmness
The cucumber should feel firm when you apply light pressure with your thumb. There should be no indentations left behind when pressed. A soft cucumber is a sign it is getting overripe and the texture has started to break down. Gently squeeze along the length of the cucumber to check for any overly soft spots.
Color
The color of the skin provides clues about freshness. A rich, dark green color means the cucumber is ripe and hydrated. As cucumbers start to age, the skin will turn a dull, pale green. Yellowing skin indicates over-ripeness and low water content. Small white or greenish-white spots are normal and come from where the flower was attached. Brown spots are a sign of decay.
Smell
Give the cucumber a sniff near the ends. It should smell fresh, similar to a leafy green vegetable. A sour or moldy odor is a red flag the cucumber is past its prime or damaged. Any rotten aroma means the cucumber should be avoided.
Pickles
For pickling cucumbers, look for firm, small cucumbers about 4-6 inches long. Avoid cucumbers with white powdery markings, which indicates sunscald damage. The skins should have small white spines and the blossom end can be slightly tapered. They will feel quite firm and make a snap sound when broken.
English Cucumbers
English or European cucumbers are longer and thinner than conventional cucumbers. They have very small seeds and thin, delicate skin. High quality English cucumbers should have smooth, shiny skin without wrinkles or signs of mold. The color can range from light to very dark green. Avoid any cucumbers that are puffy or water-soaked. The ends should not have openings or decay.
Persian Cucumbers
Persian cucumbers are short, plump cucumbers with smooth, thin skin. Look for rounded, firm cucumbers without shriveled or indented ends. They should feel heavy for their petite size. The color is typically medium green but can sometimes have faint white stripes. Pass on Persian cucumbers that appear puffy or discolored.
Seedless Cucumbers
Seedless or burpless cucumbers are another thin-skinned, nearly spineless variety. They are long like English cucumbers. Look for smooth, firm cucumbers without wrinkles or soft spots. The skin should have a vivid, fresh green color. Both ends should be rounded without mold or cracks. Definitely avoid any seedless cucumbers that are spotted, puffy, or turning yellow.
Storage
Once you bring your cucumbers home, proper storage is important for keeping them fresh longer. Here are some tips for storing cucumbers:
- Keep cucumbers in the refrigerator, ideally in a high humidity drawer. The cold environment helps slow moisture loss.
- Do not wash cucumbers before storage. The moisture can speed up decay.
- Wrap cucumbers individually in a paper towel then place inside a perforated plastic bag. This helps retain moisture.
- Cucumbers can be stored in the crisper drawer for 7-10 days.
- Check frequently and remove any cucumbers that are starting to soften or smell bad.
- Cut cucumbers can be stored in an airtight container for up to 5 days.
Common defects
Knowing what flaws to watch out for can also help you identify fresh, high quality cucumbers:
| Defect | Description |
|---|---|
| Sunscald | White patches on skin from too much sun exposure during growing. |
| Scuffs | Scraped or damaged spots on the skin, which can lead to decay. |
| Pitting | Indentations or soft spots caused by irregular watering during growth. |
| Puffiness | Water-soaked, swollen look indicates over-ripeness. |
| Shriveled ends | Indentation or dryness on blossom or stem end signals old age. |
| Discoloration | Yellowing, brown spots, or black mold spots means decay. |
| Wrinkles | Wrinkled skin is a sign of dryness and poor hydration. |
| Cracks | Deep cracks or splits in the skin can allow decay to develop. |
Ripening
Unlike some fruits, cucumbers do not continue to ripen after being picked. They are harvested when fully ripe, so post-harvest ripening does not improve quality. Allowing a ripe cucumber to sit at room temperature simply causes it to deteriorate and lose moisture content.
Taste
Cutting into a cucumber is the final way to check for quality. The inside flesh should be relatively firm, not mushy. There should not be any hollow sections or large seed cavities. Taste a slice for flavor. It should taste fresh and mild, not bitter. Extreme bitterness, off-flavors, or mushiness means the cucumber is overripe.
Pickling Cucumbers
For pickling cucumbers, inspect the inside for signs of over-ripeness. Cut open a cucumber. It should have tiny immature seeds and firm, moist flesh. Avoid pickling cucumbers with enlarged or jelly-like seeds. Hollowed out centers or any water-soaked appearance also indicates over-ripeness.
Organic vs Conventional
Organically grown cucumbers are a good choice if you want to avoid pesticides. Conventionally grown cucumbers may have somewhat thicker skins with a wax coating to help preserve freshness. There is little difference in flavor or texture. Choose based on your budget and preferences around organic produce.
Common Cucumber Varieties
There are many cucumber varieties to try. Here are some of the most common types found in grocery stores:
| Variety | Description |
|---|---|
| Slicing | Smooth, dark green skin. Crisp and mild tasting. Good for salads and fresh eating. |
| Pickling | Small size, tender skin with spines. Used for pickles. Can be pickled when 2-5 inches long. |
| English/European | Very long, thin, and seedless. Sweet, delicate flavor. Skin has faint white stripes. |
| Persian | Mini 3-5 inch size, smooth skin. Crisp texture and mild taste. |
| Lemon | Round shape, yellow-green color. Sweet mild flavor with lemony overtones. |
| Apple | Round shape, crunchy texture, sweet taste. Fruity flavor. |

- Promoting weight loss
Downsides
Cucumbers are very low in calories and carbohydrates. They do contain some antioxidants and beneficial plant compounds. However, they are not a very nutrient-dense food. Cucumbers provide small amounts of vitamins and minerals, but minimal fiber, protein, or healthy fats.
Cucumber skins can be tough to digest for some people. Many also find excessive cucumber consumption leads to bloating or upset stomach. This is due to cucurbitacins. Some people show sensitivity or intolerance to these compounds.
Allergy
Cucumbers are generally not common allergenic foods. However, cucumber allergy can occur in some individuals. Symptoms may include:
- Itchy mouth or throat
- Swelling of the lips, tongue, and throat
- Skin rash or hives
- Digestive issues
- Breathing difficulties
People with allergies to birch pollen or certain plant foods in the Cucurbitaceae family are more likely to react to cucumbers. See an allergist if you suspect a cucumber allergy.
Environmental Impact
Conventionally grown cucumbers have some downsides in terms of environmental impact. Potential concerns include:
- Use of chemical pesticides, insecticides, and fungicides that can contaminate soil and waterways.
- Pollution and greenhouse gases from transportation, often imported from other countries during the winter months
- Monoculture farming practices that limit biodiversity
- Overuse of fertilizers that run off into water systems
- Unsustainable water usage for irrigation
Buying locally grown, organic cucumbers can help reduce your carbon footprint. Growing your own cucumbers is also eco-friendly.
Cost
Cucumbers are generally inexpensive, typically ranging from $0.50 to $1.50 per pound. Pricing can depend on:
- Variety – Specialty English or mini cucumbers cost a bit more than standard varieties.
- Size – Smaller cucumbers are sometimes priced higher per pound.
- Season – Prices are higher in winter when supply is lower.
