Side-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Open a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Alcoholic drinks from Jerez–Sanlúcar–El Puerto triangle, Andalusia, Spain
Sherry — fino and manzanilla (biologically aged under flor)fino
Palomino must is fermented dry, lifted with grape spirit to about 15 % and put into oak butts that are not filled to the top. A film of flor yeast grows on the wine's surface, shields it from air and slowly changes its flavour, while the wine moves down a stack of casks (criaderas and solera) for at least two years on average.
Neutral alcohol of wine origin of at least 96 % vol, or wine or raisin alcohol of 95–96 % vol[pliego2026]

Palomino must is fermented dry, lifted with grape spirit to about 15 % and put into oak butts that are not filled to the top. A film of flor yeast grows on the wine's surface, shields it from air and slowly changes its flavour, while the wine moves down a stack of casks (criaderas and solera) for at least two years on average. Made in 5 steps over 2 years. The longest step, age in criaderas and solera, takes at least 2 years (Junta de Andalucía 2026). Saccharomyces cerevisiae flor strains, once classed as races beticus, cheresiensis, montuliensis and rouxii does most of the fermenting.
Fino ages only under flor, a living film of yeast on the wine. Amontillado starts under flor and finishes in contact with air, while oloroso ages only without flor. The tier system blends young wine into old, so a fino has an average age, not a vintage.
ManzanillaFino-style wine aged under flor in Sanlúcar de Barrameda, under its own DOP; under the Jerez rules, fino may be aged anywhere in the zone except Sanlúcar.
Fino ViejoFino with an average age of at least seven years, showing slight oxidation.
AmontilladoBiological ageing under flor first, then oxidative ageing.
Palo cortadoMainly oxidative ageing after the first flor disappears.
OlorosoOnly oxidative ageing, after the first flor disappears.
VOS and VORSWines of more than 20 and more than 30 years.
Montilla-MorilesThe new wine is kept unfortified in clay or cement jars of 2,000–10,000 L before entering the tiers.
The DOP specification dates wine-growing around Jerez to Phoenician times and cites ordinances of the Jerez wine guild from the 16th century. Local wine was a frequent cargo on ships to the Americas and northern Europe, and fortifying it ("abrigado") to stop it spoiling on long voyages is said to have favoured the flor yeasts through natural selection. The criaderas and solera system goes back to the 18th century, and Spain's first denomination-of-origin regulation was published in January 1935.
