Suitability for cultivation and agronomic production
Macabeu B is a productive, vigorous variety which grows erect and must be short-pruned. It is sensitive to wind damage. Planting in cool and humid areas along with too dry soil, causing the variety to be subject to drying out and early leaf drop,  should be avoided.  
Sensitivity to diseases and pests
Macabeu B is rather sensitive to mites, grey rot and bacterial necrosis. 
Technological potential
The grape clusters are very large and the berries moderate to large size. Depending on growing conditions, Macabeu B can be used to produce sparkling or natural sweet white wine. The dry white and sparkling wine are light, pleasant but oftentimes lack acidity and a bit of finesse. The aromas (sometimes with notes of fennel) are likewise not very intense.
