A twin-gear juicer such as one of those in the Tribest Greenstar series can extract the most juice from greens like kale, spinach, and wheatgrass, but isn’t good at juicing fruit. The juicers in this series are specialty machines usually used in professional juice bars; they’re also quite expensive. We did not test any twin-gear juicers for this review.
Chef Liana Green told us that a good juicer can “juice green leafy vegetables and produce a high yield from ingredients.” The most efficient juicers will squeeze your fruits and veggies dry. The centrifugal juicers averaged a speedy two minutes per glass of juice, but they also tended to be quite messy, splattering juice everywhere if we placed our own glasses beneath the juice spouts. The cold-press juicers were generally quieter and neater during juicing, leaving us with a much cleaner countertop — but they required about seven minutes to fill one glass.
Another important consideration is where you plan to store your juicer and how easily you’ll want to access it. While horizontal-masticating juicers can churn out high volumes of juice, you may not have space for them. Plus, they tend to weigh more so tend to be difficult to move from closet to counter. The small footprint of vertical juicers is ideal for smaller kitchens with limited counter space and can often tuck under cabinets. Lightweight centrifugal models are perfect if you need to move your juicer from storage space to counter. Just make sure whatever model you pick can handle the volume of juice you plan to make: smaller juicers equal smaller amounts of juice per batch.
