Gervin GV1 Universal Wine Yeast – 5g

Gervin GV1 is a reliable, general-purpose wine yeast used across France for making both white and red wines.

It’s ideal for home winemakers looking for something that just works — clean fermentation, low fuss, and versatile enough for most country wine recipes.

It handles sulfites well (up to 100ppm), works at cool temps (15–25°C), and settles out cleanly at the end.

Whether you're fermenting florals like dandelion or fruitier wines like banana, GV1 is a solid choice.

How to Use Gervin GV1 Yeast

Simple Method: Just sprinkle it directly onto the surface of your must. No need to stir it in — it’ll activate and get going on its own.

Optional Yeast Starter: Want to give fermentation a stronger start? Here’s how:

1. Add 1/2 tsp sugar and the sachet to a clean glass.
2. Top with ~50ml of lukewarm water (20°C).
3. Cover the glass and leave it for 15–20 mins.
4. While it activates, stir your must to introduce oxygen.
5. Pour in the starter, fit your airlock, and let it do its thing.

Brewer’s Tip

GV1 is great for cooler brewing spaces — like a UK shed or cupboard — as long as you stay above 15°C.

Don’t rack too early. Let it ferment fully and clear on its own — that’s where you’ll get the best flavour and clarity in the bottle.
