Choose the carrots you want to grow by the carrot flavor you most enjoy. There are three common carrot flavor descriptors: sugary, pine-parsley, and woody.
Carrot flavor is genetically determined—some carrots will simply be sweeter than others. Growing carrots when days are warm and nights cool and growing carrots in loose, organic soil can enhance a carrot’s natural flavor—but will not make a less sweet carrot sweeter.
Some carrot varieties are more sugary, others are more parsley flavored, and others naturally woody in taste. Commonly sweet-flavored carrots are preferred for eating out of hand. All carrots when cooked will be sweeter flavored than when eaten raw; that’s because cooking weakens a carrot’s cell walls and releases the sugars inside.
All carrots mature into their flavor. They become tastier as they grow. The taste of a carrot is driven by natural chemicals.
How carrots get their flavor. Carrot flavor and aroma are made up of sugars and terpenoids. The natural sugars—sucrose, glucose, fructose, and maltose—give carrots their sweet flavor. The organic chemicals or compounds called terpenoids give carrots their characteristic aroma.
Young carrots develop terpenoids first; these are volatile compounds, meaning they are aromatic. Terpenoids can smell like pine, wood, citrus, and turpentine. A carrot harvested too early can taste bitter and soapy.
As carrots grow, natural sugars develop through photosynthesis and are stored in the root. When days are warm and nights cool, carrots make sugar during the day, but don’t expend that sugar energy at night. In other words, the carrot grows sweeter. (When nights are warm–60°F or greater, carrots respire and burn but sugar energy.)
Carrots are sweetest when they mature at the time of year when the days are warm and the nights are cool. As well, the best time to harvest a carrot is at the end of a warm day as it finishes manufacturing new sugars through photosynthesis.
In the life of a carrot, terpenoids-driven taste come first and, in time, are balanced with sugar flavors. The sweet carroty flavor is the perfect combination of terpenoids and sugars.
Harvest for flavor. You can begin to harvest carrots as soon as they are big enough to eat, but sugars concentrate as carrots mature. When a carrot reaches the peak of maturity it will be the most vibrantly colored. Depending upon the color of the carrot that may mean it will be a vibrant orange, red, yellow, purple, or white. Within two or three days of reaching full color, a carrot’s color will begin to mute and, at the same time, sugars will begin to turn to starches and in time the flavor will wane.
Cooking breaks down the terpenoids in carrots and at the same time releases natural sugars. Cooked carrots will be sweeter than raw carrots.

Quick Carrot Growing Tips:
- Grow carrots in loose soil free of stone and obstacles; this will allow the roots to grow straight and unimpeded. Roots will fork if they hit an obstacle.
- Grow carrots in soil rich in organic matter; feed carrot beds with aged compost. Avoid nitrogen rich fertilizers; too much nitrogen can cause carrot roots to fork. Compost is rich in phosphorus and potassium which help keep roots from becoming hard and woody.
- Thin seedlings early and give roots room to grow; unnaturally short roots can result from overcrowding.
- Keep the soil moisture even; splitting roots is caused by too much water followed by a dry spell.
- Keep root tops covered with soil to avoid green shoulders and bitter flavor.
