A wine app built in Australia

Barello started because I'd spent a decade scanning wine into Vivino and what came back was offers to buy more, not advice on what to open. So the data you put in works the other way. Wine, spirits and cocktails sit in one household inventory, shared with everyone in the house, from a cellar-door dozen to the bottle someone brought to dinner, and every wine carries a drinking window that adjusts for where you keep it, free.

It's built in Melbourne by a two-person studio and priced in Australian dollars.

It's free to use. Here's what joining early gets you.

Add a bottle and its region is placed for you: a hundred-odd regions, zones and sub-regions from the Wine Australia register are in the list, Broke Fordwich to Wrattonbully, so a McLaren Vale Grenache reads as McLaren Vale, South Australia, Australia rather than as an Australian red.

The grapes Australia plants each carry a drinking window, Shiraz, Cabernet, Chardonnay, Grenache, Riesling and Semillon down the list to Tempranillo, Durif, Mataro and Fiano. The window is drawn for the grape and the vintage, then moved for the house it's in, which is the part below.

Every published drinking window quietly assumes a cellar at about 13 degrees, and Australian homes don't keep wine anywhere near it. A Brisbane cupboard stays warm most of the year with little overnight relief. A Melbourne one swings between a cold snap and a scorcher within the same week. Both run a bottle's clock faster than a wine fridge does, just differently.

Barello asks where you live, reads ten years of daily temperatures for your town, once, then asks where in the house the wine sits and whether that room is air conditioned. Melbourne comes out mild, Brisbane warm. Ten good years in a cellar is seven in a Melbourne cupboard and six in a Brisbane one; on a living-room shelf, six and five. Brisbane with the air conditioning on comes out the same as Melbourne without it. How that is worked out goes through the science and the limits on it.

Above about 25 degrees a wine isn't ageing faster, it's spoiling, and a garage or shed is over that line in both cities, so it says not to keep wine there rather than quoting a nearer date. It never stretches a window either: the published dates already assume good storage, so the kitchen fridge doesn't buy extra years.
