Processing Tomato Seeds
Eight full-season hybrid varieties for California canners and food processors. Inter, Thick, and Inter/Thick classes. Race 2 and Race 3 resistance packages. All 125 days to maturity.
Processing Classes
Varieties are grouped by juice consistency and intended processing use.
Intermediate juice consistency with thicker pericarp wall. Designed for peel and dice operations where fruit integrity and appearance matter. Higher Brix supports premium quality grades.
Pure intermediate class — the largest fruit in the lineup. Controlled vine type with exceptional Brix and color metrics. Ideal for premium whole-peel canning operations.
Maximum wall thickness and low Bostwick consistency — optimized for paste yield. These varieties convert more fruit weight into usable paste per ton. High lycopene supports color grade premiums.

Quality Metrics Explained
What the numbers mean for processing operations and finished product quality.
Brix
Soluble solids content (sugars, acids, lycopene precursors). Higher Brix = more usable product per ton. California processing tomato average: 4.8–5.2%. Orsetti lineup: 4.54–5.31%.
Wall Thickness (mm)
Pericarp thickness. More wall = less water = higher paste yield per ton. Critical for paste operations. Every 0.1mm difference matters at scale. Lineup range: 5.97–6.37mm.
Juice Bostwick (J.Bost.)
USDA method measuring juice flow rate in cm/30 sec. Lower number = thicker juice = better paste viscosity. A reading below 12 indicates premium paste consistency. Lineup range: 11.36–14.23.
Lycopene (mg/100g)
Red carotenoid pigment. Determines color grade and nutritional value. Higher lycopene supports premium USDA tomato color grades. BOS 6848 leads the lineup at 10.24 mg/100g.
Serum Viscosity
Lab measure of the thick fraction. Complements Bostwick at industrial scale. Higher serum viscosity supports better texture in finished paste.
a/b Color Ratio
USDA Lab color measurement. Higher ratio = more red, less yellow. Critical for premium paste and sauce grades. Lineup range: 1.91–2.02 (where available).

Common questions
What processing tomato varieties does Orsetti Seeds currently offer?
Orsetti Seeds offers eight commercial hybrid processing tomato varieties for the 2025–2026 season: BOS 811, BOS 4565, BOS 7708, BOS 8422, BOS 8423, BOS 7704, BOS 7705, and BOS 6848. Varieties span Inter, Thick, and Inter/Thick processing classes with Race 2 and Race 3 disease resistance packages.
What is the difference between Inter, Thick, and Inter/Thick classes?
Processing class describes juice consistency and intended use. Inter (Intermediate) varieties produce a juice suitable for peel and dice operations. Thick varieties have thicker walls and lower Bostwick readings, optimizing paste yield per ton — the standard for tomato paste and puree production. Inter/Thick varieties balance both characteristics for flexible processing.
What disease resistance do Orsetti processing tomato varieties carry?
Most varieties carry VFFFNSW resistance — Verticillium wilt, Fusarium wilt races 1, 2 and 3, Nematodes, Stemphylium, and crown Wilt. BOS 811 additionally carries tolerance to EFH (early fusarium) and FSSC races 3 and 4, making it the recommended variety for fields with documented crown rot pressure.
