Metté Spiritueux de Poivre (Pepper)

I couldn't find specific serving suggestions for Metté Spiritueux de Poivre 35cl. However here are some general ways to serve or enjoy a peppery spirit:

- Use in cocktails: Add a dash to enhance flavor.
- Serve chilled: Enjoy on its own or mixed.
- Pair with spicy dishes: Complement bold flavors.
- On the rocks: Savor with ice for a smoother taste.
- Use as a digestive: Traditionally enjoyed after meals.

For optimal storage of Eau de Vie (a type of eau de vie like pepper spirit) the practical recommendations are as follows:

- Temperature: Store at a constant cool temperature ideally between 13°C and 16°C (55°F to 60°F) to preserve quality and prevent spoilage or accelerated aging. Avoid temperature fluctuations which can damage the liquid by expanding and contracting the bottle contents and possibly dislodging the seal[citation 2].

- Light exposure: Keep the bottle away from direct sunlight and strong light sources as UV light can degrade the spirit's quality over time. A dark place or a cupboard is preferable[citation 5].

- Sealing: Ensure the bottle is tightly sealed with its original cap or cork to minimize oxygen exposure which causes oxidation and quality loss. For opened bottles it is particularly important to reseal tightly to maintain freshness.

- Bottle position: Unlike wine eaux de vie should be stored upright to avoid prolonged contact between the spirit and the cork which could degrade the cork and allow leakage or contamination[citation 2]. Horizontal storage is generally not recommended for spirits.

- Humidity: Maintain moderate humidity ideally around 55% to 70% to keep corks from drying out or becoming moldy. However spirits are less sensitive than wine to humidity extremes[citation 1].

- Special tips: Store in a stable environment away from kitchen heat vibrations or frequent temperature changes. Avoid sub-zero freezing temperatures which can alter the spirit’s molecular integrity[citation 4].

For opened bottles in addition to keeping them sealed tightly and stored upright try to minimize the time the spirit is exposed to air by limiting how long the bottle remains open.

Unopened bottles can be stored longer under these conditions without significant deterioration while opened bottles should ideally be consumed within a reasonable time frame to enjoy optimal freshness and aroma.
