Spring wheat is planted in the spring, while winter wheat is planted in the fall and it lays dormant over the winter and is harvested in the summer. Barley and oats are almost all spring crops and therefore chodosh. Malt comes from barley and is used for several purposes. Malt may be used for flavoring or coloring. In Corn Flakes, Rice Crispies malt is used for flavoring, by most pretzels it is used for coloring.
Beer also contains malt.
Most vinegar-based items such as the common household vinegar, ketchup, mayonnaise, mustard, pickles, etc. is permitted. There are specialty vinegars such as malt vinegar, terragon vinegar and salad vinegar which are made with a high concentration of chodosh malt. The new spring crop of oats is harvested in mid July, the new spring crop of wheat is harvested in early August, and the new spring crop of barley is harvested in the end of August. There is a certain period of time that elapses till the new crop reaches the consumer. The commercial bakers are concerned mainly with the gluten content of the flour.
